Abstract

Crop yields were measured using no-compost check strips in large-scale production fields to determine the impact of a one-time compost application. Adding compost to irrigated corn, irrigated soybeans and dryland corn acres significantly increased yields. Altering the application rate from 0 to 20 to 40 ton per acre did not significantly increase grain yield. However, all yields made biological improvements under irrigated conditions when compost was added.
