1. Long-term Crop Rotation Impact on Soil Properties and Crop ResponseCrop rotations can be part of sustainable agriculture production by their effectiveness depends on understanding how crop rotations affect above- and below-ground crop characteristics. Objectives were to investigate crop rotation effects on shoot dry weight and root characteristics of cereal and grain legume crops at anthesis as well as on grain yield. Rotations were corn (Zea mays L.)-soybean [Glycine max (L.) Merr.], (CS); corn-soybean-spring wheat (Triticum aestivum L.)-field... S. Osborne, R. Lehman, W. Riedell, B. Chim |
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 |
