Implementation of Cover Crops in Corn and Soybean Systems in Nebraska
November 29, 2016
A short review of cover crop research conducted at four University of Nebraska research fields (two irrigated, two dryland) to study the feasibility and impact of winter cover cropping on soil quality, soil water, and crop yields in corn-soybean systems. Objectives were to quantify cover crop emergence, fall and spring biomass production, soil water changes, soil chemical and physical property changes, and crop yields.
