Fall is just around the cornerand it has been a trying seasonfor many in the turf grass
industry. Floods in southern
Ohio to droughts in the north,
most of us are looking forward
to the winter schedule.
The time to plan for next
year is rapidly approaching. Make the OTF Conference
and Show part of your December activities. The show will
be in Columbus again this year Decem ber 3-6.
We have an outstanding program this year with many
notable speakers. Our equipment show is second only to
the G.C.S.A.A. National Show. Some of the major m anu-
facturers choose our show to debut new products. You canget the latest on new chemicals and research projects
from our O.S.U Turfgrass Science Team and their peers
from other universities.
One of the changes this year will be our annual lun-
cheon. While p lanning th is years program it was suggest-
ed that OTF move the awards luncheon to the evening.
The lun cheon is always well attended, h owever most of
the company owners and representatives that support
OTF are on the exposition floor, and are unable to
attend. With this new format our strongest supporters will
have the opportunity to meet the awards and scholarship
winners, and see how their generous support is dispersed
to the turf grass industry. Everyone is invited to attend th eAwards and Scholarship d inner at 7:00 p.m., Wedn esday
December 5.

Sports TurfTips
September is a stressful time for all of us
working in the sports turf industry. Summerdrought and high temperatures may havecaused grass dormancy and even death.Management of the key factors: soil, water,plant nutrition & mowing, are paramount atthis time of year because the fall playing sea-son is just around the corner. Now is the timeto get the field looking and growing at itsbest. We can approach field maintenance intwo ways:
1. Renovation Maintenance
(e.g. soil cultivation, overseeding)2. Presentational Maintenance(e.g. mowing & painting)
Renovation mainten ance is necessary in all spor ts if
you are to return the field to 100% desirable grasscover that will withstand the rigors of play. Renovation
may involve complete field reconstruction or merely
light overseeding, depending on damage, the level of
use, & money available.
An innovative machine from the Koro equipment
company (from H olland) has made field renovation
more accessible to many field managers in Europe and
more recently in the United States. The Field
Topmaker from Koro could be described as a high-pow-
ered flail mower th at has the ability to remove debr is by
mean s of a conveyer in to trailers for disposal. The top
of the grass is removed but the body of the plant
remains intact, thus allowing re-growth. In essence, one
pass with the Koro machine can outweigh the benefits

of continual scarification. The machine is also being used
to remove the entire surface of the field in one swift oper-
ation. O nce the field sur face is removed, it is re-cultivated,
possibly amen ded , and seeded with desirable grasses. This
process has had an enormous impact in Europe, where
the majority of clubs have no financial resources to
undertake reconstruction but h ave succeeded in attaining
a suitable degree of surface drainage.
While some facilities have the time an d th e money tocarry out major renovation prior to the fall playing season,
realistically this does not happen for many field man agers.
The window of opportunity between playing seasons is
very short, and in many cases, non -existent.
Concentrated efforts are needed during these windows
of opportunity for implementation of several key manage-
men t strategies:
Alleviation of soil compaction Adequate, uniform irrigation A fertilizer program suited to the fields needs Mowing
Over-seeding and/ or sodding
For easy reference, Table 1 can be used as a guide to
these management points. Remember that there is a
geographical and agronomic diversity throughout playin
fields that may demand specific maintenance and no
managemen t plan is a panacea.
Most importantly, undertake regular field inspec-
tionstake the time to walk the entire field so that an
effective management program can be put together.
Carry out a visual inspection to check grass color/ desity & health. Identification of certain weeds, e.g.
knotweed, can be a sign of soil compaction
Inspection of the grass may indicate that the mower
blades are dull and have ripped the turf plants leavin
an undesirable surface.
Always be alert for pest or disease damage. For
example, grub season will be upon us soon, so initiat
monitoring techniques to identify these problems.
Perform a soil inspection to check dryness/ depth of
water penetration after irrigation, compaction, and
root length . Send samples away for a routine soil test
at a reputable laboratory.

Do not remove more than 1/3 ofthe grass plant - any more willshock the turf and weaken thegrass plants. Change the direc-tion of mowing each time.Ensure mower blades are sharpand at the correct height. Donot mow too fast.

Irrigation
As a guide, it is advisableto replace water lostthrough evapotranspiration
(ET)
The ET rate can be obtainedthrough the local MET office. Avisual daily inspection of thesoil will also indicate drynessand depth of water penetration
after irrigation (ideally about 6inches)
There are many variables like amount ofplay, soil percolation and infiltration rates,game times, etc. that affect irrigation rates,timing, and frequency. Agronomically, lessfrequent irrigation is best. Wet soils should
be avoided as much as possible prior toanticipated play.

There is no ideal mowing height. Seasonal
changes in mowing height are also influenced by the
type of sport and the surface speed required. The rec-
ommendations in Table 1 are a guide to mowing
heights but the turf may be cut shorter. The lower the
grass is cut, the more importan t it is to follow the basic
rules: mow frequen tly and always observe the 1/ 3 rule.
Closer-cut turf will require more water & fertilizer to
compete with weeds and disease problems.

Turf managers have utilized late seasonnitrogen fertilization, sometimes referred toas fall fert ilization, for years. This type offertility program involves the application ofmuch of the seasons nitrogen during thelate season months of September throughDecember. It is important that late seasonfertilization not be confused with dormantand/or winter fertilization. The latter methodimplies that fertilizer applications are madeafter the turf has lost most or all of its greencolor and is not actively growing. This differsnotably from the late season concept, whichrequires that nitrogen be applied before theturf loses its green color in the late fall.
Late Season Fer t ilizat ion (LSF) for Cool Season Gr assesLate season fertilization is popular becausemany of the agronomic and aesthetic advan-tages attributed to its use supposedly arenot realized when spring and/or summerfertilization are practiced. Purported advan-tages of the late season concept include:
Better fall and winter color
Earlier spring green-up Increased shoot density Improved fall, winter, and spring root
growth Enhanced storage of energy reserves
(carbohydrates) within the turf plant
Figure 9:Essential Nutrients
8/14/2019 119875

TimingThe late-season nitrogen fertilization concept is
designed to apply nitrogen during that period of the
year (late fall) that will favor root growth over shoot
growth, an d favor a positive carbohydrate balance.
Shoot growth of cool season grasses occur most readi-
ly in the temperature range of 50-65F. Root growth ofcool season grasses will continue at soil temperatures
close to freezing. When air temperatures in late fall
consistently drop below 50F shoot growth slows or
ceases but soil temperatures are still in the favorable
range for significant root, rhizome, and stolon growth.
LSF capitalizes on this differen tial in optimum tem-
peratures for growth of roots versus shoots.
The timing of LSF should be made when vertical
shoot growth has stopped, but the turf leaves are still
green. Vertical shoot growth of cool season grasses will
generally slow and stop at air temperatures of 45-50(F.
A properly timed LSF will extend the green ing time
of the turf longer into the late fall and early winterwithout additional top growth. The green leaves
remain photosynth etically active producing carbohy-
drates. This carbohydrate will be more e fficiently used
to support root, rhizome, and stolon growth during
the late fall and winter period. LSF also assists in
building food reserves for the following season. It is
critical that the n itrogen be applied p rior to dorm ancy
for maximum efficiency of applied nitrogen. Poor tim-
ing is a common LSF mistake. On ce the leaf tissue has
turned brown, photosynthesis will no longer occur.
Rememberlate-season fertilization is not dormant
fertilization.
Fer t ilizer Rate & Fer t ilizer TypeIn addition to timing, fertilizer rate and fertilizer
type is critical to successful LSF. Th e most efficient
nitrogen fertilizers for LSF are those independent of
temperature for nitrogen release. Soil temperatures
and microbial activity are low at this time of year,
resulting in less effi-
ciency from strong
WIN methylene ureas,
natural organ ics, poly-
mer-coated urea fertil-
izers and other tem-
perature-dependent
fertilizers.
Urea, more water-
soluble methylene
ureas, IBDU, and SCU
are less dependent on temperature for nitrogen
release and, therefore, make excellent LSF nitrogen
sources. Nitrogen rates should be in the range of 1 -
11/ 2 pounds of actual nitrogen per 1,000 square feet.

Higher rates typically provide a better LSF response in
the late fall and a better carryover response into late
winter/ early spring. For cool season grasses, nitrogen
is the key nutrient for the LSF response with standard
maintenance fertilizer ratios being acceptable.
Proper rate and nitrogen source will result in sig-nificant carryover of nitrogen for early spring green-
up the following season. The standard spring fertiliza-
tion rate can typically be reduced to one half or less,
or eliminated, thus avoiding a spring fertilization
flush. Don t couple LSF with traditional spring nitro-
gen fertilization rates. This defeats the purpose of the
LSF strategy.
Coring and late season fertilization
A key attribute of late season fertilization is
enhanced root growth. A key attribute of coring is also
enh anced root growth in open core h oles. Coring and
late season fertilization in th e late fall are two of thebest management strategies a sports turf field manag-
er can implement. Coring the field in several direc-
tions (e.g. 6-8) can be extremely beneficial. Dont miss
out on this combo maintenance opportunity
In summary, LSF lengthen s the fall/ winter green
period and enhances the rate of spring green-up with-
out stimulating excessive shoot growth, thus allowing
the turf plant to maintain higher levels of carbohy-
drates than when spring/ summer fertilization is used.
Nitrogen applied during early spring increases shoot
growth rates and decreases the levels of available car-
bohydrates in the plant, resulting in depressed root
growth rates. LSF has no similar negative effects on
root growth. No winter damage or snow mold injury
occurred as a result of LSF. The turf manager must
maintain a good carbohydrate reserve/ balance and
maximum root mass. Proper timing and rate of appli-
cation are important in successful long-term pro-
grams. Always remember: greener is not always better.
A happy medium must be reached between agronom-
ics and aesthetics.It is important toremember that the
nitrogen source usedfor the late fall
applications beof the type that
is not dependent onmicrobial activity to
affect nitrogen release.

When many people think of the green industry,what first comes to mind is often the construction and
maintenan ce of golf courses, ath letic playing fields,
city parks and landscapes. However, when you speak
with OTF member Fred Wehr, general manager of
Woodside Cemetery and Arboretum, in Middleton,
Oh io, you come to realize that maintaining the
groun ds and landscapes of a cemeter y is a specialty
that offers its own set of challenges and rewards.Wehrs introduction to the cemetery specialty
came via his father, who was also an OTF member.
My father was with Greenwood Cemetery in Monroe,
Ohio for 38 years, he says. Although I was prepared
for a career in Forestry, he introduced me to the
important role that landscaping and proper mainte-
nan ce play to the comfort level of people who visit
cemeteries.
Wehr went on from a two-year horticulture pro-
gram at Miami University to receive his four-year
degree in Business Administration from The
University of Cincinnati. Both programs have served
to help me meet daily challenges, he says.
Some of those challenges include the u pkeep of
the landscape at Woodside Cemeter y, which recently
celebrated its 110th anniversary in June, 2001. We
have 100 acres of grass that we must regularly mow
without disturbing any markers. In addition, we
recently identified 2000 trees on our 135 acres and
tagged one of each species, for a total of 200 tags. We
must maintain the health of all these treesone of
which is a Post Oak, a member of the White Oak fami-
ly. Our Post Oak is over 110 years old.

Fred WehrGeneral Manager
Woodside Cemetery and ArboretumMiddleton, Ohio
When they tagged the trees, staff plotted the trees
on a Geographical Information System to create a
road map of the cemetery. This was a beneficial
project, says Wehr, because we know where all the
varieties of each tree are. For example, if we note that
a Nor way Spruce is diseased, we can treat it, then look
to the map to see where all the Norway Spruces are
and check out their status.
In add ition to all our trees, which earned us theadditional name Arboretum, we plant a lot of flowers:
200 flats each spring, as well as 200 flats of pansies
each fall, says Wehr. We wanted to concentrate on
bulbs, particularly tulips. However, the squirrels
appetite for the bulbs became a problemuntil we
discovered that they do not seem to like daffodil
bulbs. Now Woodside Cemetery has over 75,000 daf-
fodils planted at the cemetery. They are n aturalized in
beds or in the grass. We plant an additional 3,000-
5,000 bulbs each year. With a steel auger, we can plant
up to 2,000-3,000 bulbs in a day. We also spray a
growth inhibitor for the weeds and the grass, which
does not hu rt th e flowers, he says.We are faced with challenges like these each day,
Says Wehr. If students in various landscaping, horti-
cultural and turf management programs are thinking
about various specialty areas, I would encourage them
to consider cemetery grounds keeping and general
man agement. You have the ability to be of service to
the community, to promote a sense of well-being in
what was once thought of a dreary place, and you are
able to see the results of your hard work every day
over the long term.

Consider ing Using a Compost
Topdr essing Applicat ion OnYour Fair w ays This Fall?
New Growth and Technology
By Mike Boehm and Joe RimelspachThe Ohio State University
Department of Plant Pathology
Overview of the Composting Process
Although there are several different types of com-
posting processes, most of the compost used by the turf-
grass industry is produced via a process in which fresh
organic matter such as yardwastes, dewatered sewage
sludge or poultry manure is either piled, stacked or oth-erwise arranged to facilitate it decomposition by
microorgan isms such as bacteria, actinomycetes (a
unique type of bacteria) and fungi. As these microbes
degrade th e organic material, they generate a great deal
of heat which inactivates or kills weed seeds, plant, ani-
mal and human pathogens and many beneficial
microbes such as nitrogen fixing bacteria and biological
control organisms. As these microbes use the freely avail-
able carbon and nitrogen sources, their metabolism and
subsequently, the composting process slows resulting in a
cooling of the pile. As the compost cools, other microor-
ganisms, some wind- and yet others rain-borne, are intro-
duced into and colonize the pile. This final phase of thecomposting process is referred to as the curing stage. It
is during the curing stage that microbes capable of sup-
pressing plant pathogens such as those that cause
Pythium root rot, proliferate. The type of composting
system used (i.e. windrow versus static pile versus in ves-
sel) and the characteristics of the parent organic materi-
al being composted are two major factors which influ-
ence both the rate of the composting process and the
quality and consistency of the finished product. For
example, grass clippings degrade much more rapidly
than tree bark or wood chips. Once adequately cured, the
compost is typically screened to 1/ 4 to 1/ 2 inch and used as
a topd ressing material. Although numerous methods of
assessing whether a composted material has been adequate-
ly cured or is mature enough for use in plant production,
no single method provides all the answers and quite often
one must rely upon a collection of such assays stressing the
need for the development of practical standards and guide-
lines and future work in this area.
Step 1: Goal Setting
Deciding to use compost topdressings on your fairways is
no different than implementing other turf health or pest
management practices. Although the reasons for using
compost topdressings are man y, often times the decision
revolves around one of the following: 1) compost topdress-
ings are perceived to be an environmentally sound practice;
2) composts may serve as an excellent source of plant-avail-
able nutrients; 3) composts have been shown to provide val-ued sources of organic matter and may improve soil fertility;
and, 4) some composts have been repor ted as being able to
suppress turf diseases such as dollar spot and Pythium root
rot. Knowing ones rationale for implementing compost
topdressings is critically important because it will not only
allow you to make informed decisions as to product selec-
tion and application and timing strategies, but may ulti-
mately allow you to determine how best to m odify your
existing management practices to maximize overall turf
quality and vigor.
Consider ing Using a Compost
Topdr essing Applicat ion OnYour Fair w ays This Fall?
The use of composts to improve turfgrass health or soil tilth is not a new concept. Indeed, onemight consider it a lost art as compost applications were common until the advent of the agro-chemical revolution of the 1940s and 50s. After nearly 60 years of heavy reliance on chemicalinputs, we find ourselves in the midst of a resurgence in the use of organic matter amendmentsand topdressings. The specific aims of this article are to present an overview of the compostingprocess and to provide a four step approach for implementing the use of compost topdressingsbased on our experiences and the experiences of those superintendents with whom we have worked.

Step 2: Product Selection
Once you have figured out your goals for imple-
menting a compost topdressing program, the next
step is selecting the right compost for the job. Thismight be a case of easier said than done as one of
the major historical reasons for a reduced reliance on
the use of composts early in the 20th century in part
revolved around the reality that not all composts are
created equal. In other words, composts can and typi-
cally do vary tremendously in their chemical, physical
and microbiological characteristics. Such variation typ-
ically exists even though our knowledge and under-
standing of the complex nature of the composting
process and the parameters which influence this
process are perhaps better understood and controlled
now than ever before. As a potential user of composts,
it is impor tant to realize that some composts varymore than others and that variability in the parent
organic material being composted typically corre-
sponds to inconsistencies in the final product. As men-
tioned p reviously and underscored here, the compost-
ing process used and the consistency and chemical
characteristics of the organic material being compost-
ed are two key factors that greatly influence the consis-
tency and quality of the final composted product.
Additional factors such as the type of bulking agent
(materials such as wood chips, sawdust or crumb rub-
ber that are added to some types of compost to
increase and maintain adequate air-filled pore space
during the composting process) used, the frequency
of turning or mixing, and th e moisture conten t of the
compost all significantly impact the consistency of the
final product. Other factors such as seasonal variations
in the waste stream flow and the weather also have the
potential to adversely effect the quality of the finished
product. Consider for example the differences that
exist in th e yardwaste stream between Spring and Fall
in which grass clippings predominate in the Spring
and leaves dominate in the Fall. The experience level
of those managing th e composting facility also may
significantly influence the quality and consistency of
the final product.Even with the potential for such variations, howev-
er, there are numerous clues that might be useful in
determining which compost is right for your course.
Just as in selecting the right wine for that special occa-
sion, so too can selecting the right compost be rather
subjective. For example, often times you will read or
hear that a good compost is said to be dark in color
with a crumbly texture, a moisture content of around
40-45% and an earthy aroma similar to that of a fer-
tile soil. Such descriptions are extremely subjective.
Yet, there is great value in this type of sensory-based
assessmen t as many working in the green indu stry have
an intuitive sense for what a rich fertile soil feels, smells,
and looks like. Luckily, however, for those short in theintuition department or eager to base the ir decisions on
more quantifiable characteristics, there are numerous
physical and chemical qualities to consider.
In terms of ph ysical properties, particle size and tex-
ture are perhaps two of the most impor tant factors one
can use to assess a composts physical characteristics.
These properties are important to consider because
repeated applications of composts with excessive
amoun ts of bulking agent or oth er foreign materials
might lead to an undesired accumulation of unwanted
materials in the thatch or soil. A quick glance and a
handful of the candidate compost should provide a
rapid assessment as to whether a particular compoststexture is suitable for u se on your fairways. In regards to
particle size, we typically use and recommen d th at com-
posts used on fairway turf be screened to 1/ 8 to 1/ 4
inch to remove excessive bu lking agen t. Even then, h ow-
ever, it is often difficult to completely remove unwanted
or excessive bulking agent as thin slivers or splinters typi-
cally have the ability to pass through the screen ing
process.
In add ition to the physical nature of the compost,
there also are numerous key chemical properties and
processing information that may provide important clues
about the suitability of a par ticular compost. In all cases,
the compost producer should be willing to provide youwith the following information for each batch of com-
post prior to or at the time of delivery. Hesitation on the
part of the producer to divulge this information may
speak volumes about whether or not you should be con-
sidering their product and brings to light the impor-
tance of developing a good working relationship with
local compost producers and distributors. Ideally a sup-
plier should provide the following information: Compost
type and age; The composting process used (i.e. static
pile, windrow, forced-air static pile or in -vessel); A com-
plete elemen tal analysis including heavy metals (especial-
ly if working with a biosolids or municipal solid wastecompost); Total, ammonium and nitrate N concentra-
tions, respectively; pH; CEC, organic matter and ash con-
tent; Soluble salts (especially for animal manure com-
posts); and , the C/ N ratio. Additional information
regarding nutrient release characteristics and bulk densi-
ty of the compost might be also valuable pieces of infor-
mation and will facilitate your ability to determine n utr i-
ent loading an d mineralization rates of the compost.
Both of the latter will be extremely valuable in your
attempts to determine the magnitude and duration of
the compost. Just exactly what all this data mean s and

how it should be evaluated is the topic of several add i-
tional articles. In a nutshell, however, you can develop a
fairly rapid assessment of a composts fertilizer potential
by concentrating your attention on the: 1) pH; 2) h eavy
metal and N and P concentrations, respectively; and, 3)C:N ratio. In general, and taking into account the wide
variety of composted materials available, the pH should
range ideally between 5.7 to 7.5. In regards to heavy
metals, concentrations should be below standards
allowed by the US Environmen tal Protection Agency
Rule 503. The N, P, and K analyses in tandem with the
bulk density of the compost should help provide insights
regarding the amount of potentially plant available
nutrients supplied by the compost topdressing applica-
tion. In general, the greater the concentration of plant
available N (ammonium an d n itrate), the greater the
color enhancing and growth stimulatory effects that may
be anticipated assuming the compost topdressings are
applied during a period of active turf growth. In gener-
al, high C:N ratios (above 20:1) m ay be an indication
that the compost is not fully composted and is not ready
for use as a topdressing material. Immature composts
pose the threat of causing a phenomenon called n itro-
gen immobilization that is brought about when com-
posts with excessive C an d limited N are applied. When
this occurs, the compost microbes attempt to further
breakdown the excessive C and because th ey, like all
organisms, require a balanced diet of C and N, they
essentially out compete or steal N from the turf. The
result is that the turf goes off color and will require theaddition of additional N fertilizer to bring the system
back into balance. In general, a good target range for
the C:N ratio would be somewhere around 15:1.
Biological or microbiological ind icators of compost
maturity and turf enhancing properties also exist, how-
ever, they are expen sive and labor intensive to measure.
Besides, these drawbacks, interp retation of the results
from such tests are often difficult and ambiguous as our
understanding of the microbiology and microbial ecolo-
gy of composts and turfgrass soils is still in its infancy.
Bottom line, put most of your decision-making eggs in
the physical and chemical property baskets, respectively.
Step 3: Timing and Application Strategies
Once a compost has been selected, the app lication
of the mater ial should proceed fairly easily. The most
frequently used application method of topdressing fair-
ways with compost is in conjunction with the normal
fairway core cultivation process (hollow tines are recom-
mended) that takes place in th e Spring and Fall during
periods of maximum turf growth and recuperative abili-
ty. These are also times when average daytime tem pera-
tures do not exceed 65-70F thereby reducing the possi-
bility of either burn ing the turf through the use of hot
compost (compost containing excessive amounts of
ammonia or which are warm or h ot to the touch) or
otherwise suffocating the turf with a blanket of compost
topdressing and cores on a h ot summer day. Whetheryou decide to core first and topdress second or topdress
first and core second is ultimately up to you. One advan-
tage to coring first and then subsequently applying your
topd ressing is that you significantly minimize th e time
the compost sits on the turf. Any device that has the abil-
ity to d istribute the compost over d istances without com-
pacting the soil can be used. The rate used will depend
on numerous factors such as time of year, members
expectations, particle size, turf species and height of cut,
the n utrient loading rate of the compost being applied
and on the ability of the turf to assimilate the provided
nutrients. Members may be more demand ing of impec-
cable turfgrass earlier in the season, than towards the
end, allowing for a m ore aggressive topdressing program
in the Fall. Similarly, a product that has been screened
to a smaller diameter will moved off of the turf and into
the soil profile quicker th an poorly screened product.
Once the compost has been applied, the fairways should
be dragged to blend the compost with the pulled soil
cores. The remaining tufts of turf and th atch can then
be blown into the roughs where they can be picked up
with rotary mower fitted with a bagging attachment. The
final step in the application process is to irrigate the fair-
ways as soon as possible to reduce turf stress and the
potential for any ammon ia or thermal burn or heatinduced stress.
Step 4: Record Keeping
As with any practice, solid documentation is critical
for future reference and decision making processes. In
the case of compost topdressings, the following records
may be useful to maintain: 1) Product records such as
any physical, chemical or biological properties you may
have considered and important contact information; 2)
Economic records such that you can ultimately run a
cost-benefit analysis comparing your standard and com-
post topdressing enhanced programs, respectively; 3)
Application records such as timing, steps carried out inthe actual application process, weather data, soil temper-
atures and moisture levels, etc.; 4) Follow-up observa-
tions such as any effects observed and the magnitude
and duration of these effects; and, 5) Membership com-
ments and concerns that might be useful in later years
regarding this practice. The better your record keeping,
the greater the possibility that you will be able to assess
the pros and cons of this practice in relation to your
standard managemen t practices.

Summary and Conclusions
The use of compost topdressings can be a useful
tool for managing fairway turf. As with any initial
attempt at implementing a new management practice,
use common sense and take a somewhat conservative
approach when just getting started. In other words,
make certain to try your hand on a small scale and
evaluate the effects of compost topdressings before
attempting to tackle every fairway. The following keys
to success might be useful when attempting to maxi-
mize the implementation of compost topdressings
while minimizing any potential detr imental effects
associated with this practice.
Determine your goals for implementing a compost
topdressing program. Are you interested in com-
posts as organic fertilizers, soil conditioners or to
introduce a form of disease suppression?Determine what your goals and expectations early
in the process.
Get to know your local compost producers, distrib-
utors, other superintenden ts that h ave tried using
composts, university staff working in the area, and
state and local solid waste authority personnel and
regulations.
Remember that not all composts are created equal.
Some positively-, oth ers n egatively-, and some have
no impact on turf health and that the more you
know about the compost you are considering, the
greater the chances of a successful outcome.
Pay close attention to the consistency or variability of
products quality. The amount of bulking agent pre-
sent, the degree of maturity and the particle size and
texture of the compost are four important things for
which to look.
Make it your business to know WHAT you are apply-
ing (elemental analysis, pH, CEC, parent material of
compost, process by which it was generated , nu trient
release characteristics, organic matter and ash con-
tent, soluble, ammonia, organic acids, etc).
Combine compost topdressing applications with
Spring and Fall core cultivation events via blend ingwith cores and dragging. Avoid applying compost
topd ressings to fairways when air temperatures
are greater than or equal to 65-70F.
Modify your application rates to meet your target fer-
tility goals. Maximize the potential benefits of the
compost topdressings by making applications when
the turf is actively growing.
Develop an effective application strategy that can be
completed in a relatively short period of time from
the time the compost is applied to the time irrigation
is applied to the turf
Always include an appropriate set of internal control
plots so that you can truly gage the effects of a newly
implemented management practice. Specifically in
the case of evaluating the effects of a compost top-
dressing program for your fairways, you might con-
sider including both a non -treated area (no coring
or compost) and a cored but not topdressed area to
assess the effects of your coring and topdressing pro-
grams. Without such internal control areas, it is
impossible to accurately assess any practice.
Consider modifying your standard fertility program
to account for the additional nutrients being applied
or incorporated. Keep good records of what worked and did not work
for you and remember there are no silver bullet.
Walk before you run! As with any new practice, take
it slow at first until you get the hang of it.

Broadleaf
Weed Control
New Growth and Technology

Broadleaf
Weed Control
Whether you are a professional lawn care
operator or a golf course superinten dent it
is a usually a necessary evil to perform
some postemergence broadleaf weed control in th e
spring. Unfortunately, this has fostered the misconcep-
tion that spring is the ideal time to control broadleaf
weeds. Many of our most common and hardest to con-
trol broadleaf weeds are perennials. There are severalreasons why it makes more agronomic sense to apply
postemergence mater ials, such as 2,4-D and triclopyr,
in the fall, especially for the control of perennial
weeds:
Herbicide translocationIn the spring, perennialbroadleaf weeds such as dandelion are translocating
materials stored over winter from the taproot to the
newly emerging leaves. In the fall, the opposite occurs
as the weed translocates carbohydrates into the tap-
root for winter. Fall applied broadleaf herbicides are
much more effective because they are readily translo-
cated into the root system, resulting in death of theroot system as well as the leaf tissue.
Control in spring results in bare patchesfilled in by crabgrassSpring-time h erbicideapplications have unfortunately become a necessary
evil, either because a n ew client was secured over th e
winter or because tolerance for broadleaf weeds is low
in areas such as fairways or office park entrances.
However, application of 2,4-D and other mater ials in
the spring will result not only in possible incomplete
kill of the root system, but also a bare patch that is
quickly filled in by crabgrass and o ther an nual weeds.
Control in the fall is not on ly more effective, but also
gives the turf time to fill in the bare spot without com-
petition from most annual weeds. While postemer-
gence broadleaf herbicides will not control crabgrass,often the best control of annual grasses is a dense
stand of turf.
Less risk of damage to ornamentalsMostornamentals in the landscape and garden are very
sensitive to the effects of broadleaf herbicides, so that
even the slightest contact will cause damage. Newly
emerging leaves are especially sensitive. Damage
resulting from con tact with herbicide vapors can
occur if the herbicide volatilizes. Volatilization is more
likely as the temperature increases or when using cer-
tain herb icide formulations (m ore on this later).
However, in the fall, most annual ornamental plantsand vegetables have reached matur ity and leaves of
trees and shrubs are beginning to turn color and fall
off the plant.
Winter annualssuch as henbit and commonchickweed, are beginning to germinate in mid-to-late-
fall and can be effectively control if herbicide applica-
tion is done after they germinate.
It makes more agronomic sense to apply postemergence materials,
such as 2,4-D, MCPP, t r iclopyr, and clopyr alid in the fall for contr ol ofperennial broadleaf weeds such as dandelion and white clover.

Table 1.Perennial broadleaf weeds are most effectively controlled in the fall. Annualbroadleaf weeds can also be controlled, but are at the end of their life cycle.More effective control of annual broadleaf weeds is with preemergence herbi-cides applied in spring.

It is important to correctly identify the most problemat-ic weeds on a site, and then consider whether they are
predominately annuals or perennials. Correct identifica-
tion is usually pretty easy. However, a few of the weeds
can be confused, like the clovers (see Table 1 and the fig-
ures). Iden tification of the weed and knowledge of its life
cycle is necessary in order to best determine what control
strategies to use. For example, white clover is a peren nial
and control is most effective if herbicides are applied in
the fall. Black medic and yellow woodsorrel are ann uals.
Both are best controlled with postemergence materials
early in their life cycles. Some preemergence herbicides
are labeled for control of yellow woodsorrel. However,
this weed germinates very late and may not be effec-
tively controlled unless herb icides are also applied late
(after crabgrass has germinated) or as a split applica-
tion. Other annual weeds that are considered difficult
to control preemergently are knotweed ( germinates
very early) and spurge ( germinates very late).
Inciden tally, these two weeds are often con fused.
Spurge, however, has milky sap while knotweed does
not (See Figure 4). Properly discerning between these
two weeds may be importan t in determining the prop-
er time to apply preemergence herbicides if this con-
trol strategy fits into your management program.

Figure 1. Common chickweed (top) is a win-ter annual and often confused with mouse-earchickweed (bottom), which is a perennial. Bothcan be effect ively controlled by applying MCPP
or dicamba after common chickweed has ger-minated.
Table 1 lists the most common perennialbroad leaf weeds. Though certainly not inclusive,
the species listed easily account for 90% of the
perennial broadleaf weed p roblems in O hio tur f-
grass. Fall applied postemergence herbicides
shou ld be the first choice to contro l perennial
broad leaf weeds.
While fall applications of broadleaf herbicides
will also con trol annual broad leaf weeds, many of
these may be effectively controlled using preemer-
gence herbicide materials applied in the spring.
Table 2 lists some of the most common annualbroadleaf weeds, along with options for control
with preemergence herbicides. Since these weeds
are ann uals, they are near th e end of their life
cycle now and control with a postemergence mate-
rial may not be warranted . If there is heavy cover of
these weeds it may be advantageous to control
them n ow in order to allow the grass time to fill in
the bare spots during the fall. Remember, though,
that more effective control of these weeds in future
seasons is either with preemergence herbicides, or,
if necessary, postemergence materials applied early
in the weeds life cycle.
It is very important to select the right herbicideand the most appropriate formulation in order to
get the best possible control. Consult the label to
determine whether the addition of a sur factant is
warran ted. Ester formulations are more effective
than amine formulations, especially as tempera-
tures decline. Esters, however, are more volatile
and more care around ornamentals must be exer-
cised with these materials when temperatures are
above 60 degrees. Remember also that postemer-
gence herbicides are most effective if applied dur-
ing sunny weather with no rainfall within 24 hours
of application.
How late these materials can be applied
depen ds on weather conditions. In general, if the
plant tissue is losing quality due to frost or cold
temperatures, it is probably too late to get enough
herbicide into the root system for effective control.
Finally, herbicides applied in the very late fall have
been observed to have what appears to be little
effect. But, when the same areas are revisited in the
spring, control can, in fact, approach 100%.
