Growers that switched to planting green, say it was much easier to plant compared with planting into the decomposing-dying cover. In spite of these observations, planting green is not for everyone and one needs to assess the risk of doing so.
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.
Managing weed escapes mid-season and late-emerging weeds can have a substantial impact on the spread of herbicide-resistant weed populations the following year. View the table of preemergence herbicides that can be applied postemergence.
In some years it may be difficult to well establish a cover crop after corn harvest. This article surveys current research on interseeding into an established crop, further considerations, and how to test this practice on your farm.
Welcome to the 3rd annual Nebraska Crop Management Conference. It is my sincere hope that the unbiased, research-based information you have come to expect will again this year help improve the success of your farm or business.
Cover crop research trials were conducted in 2017-2018 at the UNL Havelock Research Farm near Lincoln to discover the impact of soybean maturity group, planting date, termination date, and herbicide use on on management of winter- and summer-annual weeds.
