1. Soil Quality and Nitrogen Availability After Eight Years of a Mixed Cover Crop - Wheat RotationDespite a large interest in cover crops in the northern Great Plains, little is known about their effect on both the following wheat crop and soil quality. In 2012, a cover crop study was started in Montana to compare wheat production and soil quality after growing cover crop mixes containing 2-, 6-, or 8-species, with both summer fallow and a sole pea cover crop control, in a 2-yr rotation with wheat. The 2-species mixes represented functional groups (legumes, brassicas, tap rooted, or fibrous... C. Jones, P. Miller, C. Zabinski, K. D'agati |
2. Snapshot of Crop Nutrient Balance with Use of a Rye Cover Crop in a Corn-soybean Rotation Under Tile Drainage in Eastern South DakotaThe purpose of this study was to evaluate the effect of using a winter rye cover crop within a corn/soybean rotation (rye seeded every fall and burned down each spring) on drainage water quality, crop nutrient status, and grain yield. Use of a winter rye cover crop to take up available N from the soil profile is a management tool that may help to lessen nutrient movement out of the soil profile while at the same time contributing to improved soil health. Winter rye is very winter hardy... P. Sexton, S. Kumar, S. Osborne, B. Brockmueller, A. Bly, B. Rops, A. Bawa, S. Bauder, J. Mcmaine |
