Red clover can be an excellent green manure that fixes nitrogen, suppresses weeds, and increases corn yields. As a slow-growing cool-season legume, it is suitable to undersowing into winter small grains in early spring.
Across Nebraska, the use of cover crops is increasing. Most commonly, winter cover crops are planted during the fallow period between corn or soybean harvest and the next crop. However, other windows for cover cropping exist in Nebraska.
Overview of two experiments conducted in eastern Nebraska to quantify the productivity and agronomic effects of diverse cover crop mixtures and to determine how several termination methods might alter those effects.
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.
