-
Direct seeding winter canola into heavy irrigated winter wheat
stubble instead of burning and disking at Jeff Schibel farm near
Odessa.
-
Safflower at Ritzville in 2015
-
New 3-year winter canola rotation added in 2015 at long-term
cropping systems trial at Ritzville. Winter canola spring wheat
undercut tillage fallow.

Soil water content at the beginning (after harvest), early
spring, and the end of fallow (just before planting of winter
wheat) and associated gain or loss of water and precipitation
storage efficiency (PSE = gain in soil water/precipitation that
occurred during the fallow period) in the 6-foot soil profile in
summer fallow in a 2-year winter wheat-fallow rotation versus a
3-year winter wheat-camelina-fallow rotation. Data are a 6-year
average.

SOIL MICROBIAL COMMUNITY CHANGES WITH INCLUSION OF
OILSEED CROPS INTO CEREAL GRAIN ROTATIONS

PhD Dissertation Research
-
Soil and rhizosphere microbial communities in agroecosystems may
be affected by soil type, climate, plant species, and
management.
The plant species (oilseed crops) and management (rotation)
factors will be investigated with four field scale experiments.
Overall Objective
-
Canola (Davenport, WA) Camelina (Lind, WA) Safflower (Ritzville,
WA) Rhizosphere (Ritzville and Mansfield, WA)
