These surveys have provided valuable information about the use of cover crops and their impact on crop production and soil health including information that helped frame policy with the USDA agencies NRCS and FSA.
Weed control in organic soybean usually includes frequent pre-plant tillage operations but spring rains often make it difficult to get into the fields for timely tillage. As a result, weed pressure can be high. Cover crops can help suppress weeds, but after corn harvest it is often too late to establish cover crops. Spring-planting cover crops may be an alternative to fall-planting.
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.
Each year, the On-Farm Research Network plans a series of update meetings and invites producers to attend in order to gain valuable crop production related information from the research projects conducted by Nebraska farmers.
