Due to the late wheat harvest throughout western Nebraska, weeds growing in unharvested fields grew much longer than usual. In some fields weeds matured and produced seed. These weed control measures and residue management will be particularly important for the next wheat crop.
This Q&A addresses questions about baling soybean residue, including its nutrient value and comparison with other sources, economic value, and what should be considered when deciding whether to bale soybean residue.
In the inaugural CropWatch podcast Extension Educator Michael Sindelar interviews Marty Schmer and Virginia Jin, USDA ARS researchers, about uses for corn residue, recommended removal practices, and when residue removal is not recommended.
The Crop Residue Exchange is an interactive online tool to help crop and cattle producers connect and develop mutually beneficial agreements to use crop residue for grazing. A new feature allows producers to also list forage cover crops for grazing.
Soil is the single most important resource on which our agriculture depends. Proper soil management is necessary to sustain long-term agricultural productivity. Soil loss through erosion or run-off hurts agricultural production with depletion of organic matter and fertility. It also has environmental implications.
University research looking at CO2 emissions from two types of residue removal (baling and grazing) compared with a control treatment found little day-to-day impact; however, when looking at cumulative data for the whole year, grazing did appear to affect cumulative CO2 emissions in irrigated crop-livestock systems. This data represents the first year of this study.
