Additional Funds Leveraged
Partial funding to support this project has been obtained from the WSU Biofuels Project in FY 2008, 2009, and 2010.
Impacts
To date we have found no benefits to wheat following winter canola. Winter canola uses more soil water than winter wheat, so the subsequent yield of wheat after winter canola tends to be significantly less than after winter wheat. The yield reduction is directly proportional to the amount of soil water (we have developed a model to predict wheat grain yield based on soil water and April, May, and June rainfall).
