Compost Manufactured Soils in

Landscape construction

Reducing the need for

harmful floodplains and

farmland soil stripping

activities is the first benefit

of selecting compost

manufactured soils.

The true value comes with

the higher quality topsoil

enriched with organic

matter, nutrients and

calcium.

And since manufactured

topsoil is screened during

production various grades

are available such as

sportsfield turf, lawn or

wetland soils.

Added benefits of moisture

retention for drought and

compaction resistance

Benefits to Municipalities

• Water Conservation

(reduced watering)

• Minimize harmful topsoil

mining practices

(floodplains etc)

• Enhanced Wellfield and

Aquifer Protection

(erosion protection and

pesticide absorption)

• Cost Savings (less costly

turf maintenance)

Topdressings

Compost

topdressings in

combination with

core aeration can

be used to repair

and enhance

existing turf or

Organic Fertilizers

• Granular Organic Fertilizers (dehydrated pelletized poultry manure)

• Organic Topdressings (for turf restoration and maintenance)

• Cost-effective and safe

• Usage leads to reduction in pesticides

Composts as Organic Bio-Fertilizers

taking on increased interest from

Agriculture (especially in light of recent

price increases in chemical fertilizers):

• Research on-going at NSAC,

Fredericton Research Station,

Cavendish and McCain’s Field

Research Stations all provide

confirmation of increased crop yields

from organic inputs

• High-Value Crops in Potato,

Blueberry, Cranberry, Orchard and

Vegetable production transitioning to

organic production

Sustainable Organic Bio-

Fertilizers from Compost

Pelletizing Plant contains dryer, grinders, mixers and pellet dye to pasteurize, compress, and produce granular fertilizer from poultry manure.

Produced in two different grain sizes for turf or agricultural applications

End product fertilizer provides organic matter, nutrients, iron, calcium, lime, and microbial matter to soil for overall soil health.

R&D for Innovative Development and Commercialization

of

Dr. Gordon Price, D.H. Lynch, 1Department of Plant and Animal Science (Nova Scotia Agricultural College)

Introduction

Novel Technology (dehydration) to process compost and

manure feedstocks into organic Dehy-Topdressing or

Bio-Fertilizer for turf, greenhouse and

landscape/horticulture usage.

Objectives

Quantifying and characterizing, the physio-

chemical properties and the horticultural

suitability of compost, manures or agri-food

residues within bio-fertilizer blends

Assess turf and plant growth performance

from Dehy-Topdressing and Bio-Fertilizer

amendments added during trials

Methodology

Acknowledgments

1. The physio-chemical properties (pH, EC,

nutrient content and release mechanisms) will

be tested.

2. A series of greenhouse and field studies at

NSAC (each a RCBD with 4 replicates) will be

conducted.

Key Benefits and Characteristics of

Envirem’s

“Dehy-Topdressing (Soil Amendment)”

• Made with 100% “Environmental Sustainable” and “Organic Certified” ingredients.

• Made without reliance on fossil-fuel based resources of Synthetic Chemical fertilizers or non-renewable Peat-based or mineral fertilizer ingredients.

• Lightweight, Odorless formulation.

• Dehy-Topdressing formula containing natural “Composted” sources of organic nutrients and microbial boost for healthy, vibrant lawns.

• Professional quality topdressing that meets or exceeds important landscape/turf performance parameters for organic matter, nutrient release, and pH balance.

• Product should be of appropriate density to ensure bulk fertilizer sacks volume-out and weigh-out within truck transportation to increase economically viable transportation distances and expand market regions.

• Dehy Topdressing product should be of sufficient dryness to suppress seed germination while in storage (important for potential use as a seed-n-feed product).

• Other potential beneficial characteristics that may be important to turf maintenance markets include: – calcium carbonate equivalency (CCE%) which would supplement lime,

– presence of enhanced iron content levels which support dark green foliage colors,

– a dark black color which improve snow/ice melt and may improve early greening,

Key Benefits and Characteristics of

Envirem’s “Bio-Fertilizer”

• Made with 100% “Environmental Sustainable” and “Organic Certified” ingredients.

• Made without reliance on fossil-fuel based resources of Synthetic Chemical fertilizers.

• Made without reliance on mined sources of phosphorous or potassium fertilizers.

• Bio-fertilizer recipe must contain ingredients that would maximum potential end-product concentrations of total soluble and insoluble forms of Plant Macro-Nutrients of Nitrogen, Phosphorous and Potassium.

• Bio-Fertilizer recipe may also benefit through optimum concentrations of Plant Micro-Nutrients such as magnesium, calcium, sulphur, iron, zinc etc.

• Dust-free and Odorless formulation is important for end-users.

• Uniform spherical particle sizes of suitable density and durability for all purpose uses and readily adapted to typical spreader types and settings.

• Important particle density, uniformity, roundness and SGN grain size must meet needs of conventional turf and agriculture spreading equipment, and fulfill spread patterns, consistent distribution and application rates.

• Bio-Fertilizer formula containing natural “Composted” sources of organic nutrients and microbial boost for healthy, vibrant plants.

• A professional quality bio-fertilizer that meets or exceeds important greenhouse performance parameters for nutrient release, solubility and salts contents
