Compost Carryover Effects on Soil Quality and Productivity in Organic Dryland Wheat

Organic Agriculture November 16, 2015 Print Friendly and PDF

This webinar was presented by Jennifer Reeve and Earl Creech of Utah State University on November 10, 2015.

About the Webinar

Dryland organic wheat production in the arid West encompasses a large percentage of the organic wheat acreage in the United States. However, declining wheat yields and poor quality caused by lack of soil fertility and growing weed pressure threaten the economic and environmental sustainability of these farms. Composts have a strong carryover effect with potential to improve soil fertility and productivity of dryland organic wheat systems but the long-term benefits have not been thoroughly evaluated.

A new multi-state long-term project was initiated in the fall of 2014 involving a collaboration between scientists at Utah State University, Washington State University and the University of Wyoming. The long-term goal is to develop long-term on-farm research sites devoted to testing and showcasing organic dryland wheat management strategies for increased water use efficiency, weed management, soil quality, wheat yield and quality, and economic viability for dryland organic wheat growers. This webinar will present data from the original compost carryover research project in Utah as well as introduce the goals and objectives of the new multi-state long-term project.
