Spring-planted Cover Crops for Weed Control in Organic Soybean

March 25, 2020

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.

Cover Crops Benefit Nebraska Agroecosystems In Many Ways

January 9, 2019

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.

Figure 1. Cover crop trials were conducted in 2017-2018 at the UNL Havelock Research Farm near Lincoln to discover the impact of several practices on management of winter- and summer-annual weeds.
