1. Evaluating the Trade-offs of Cover Crops in Dryland Wheat Systems of the Colorado PlateauOn the semi-arid Colorado Plateau, dryland farmers are challenged by severely degraded soils and low and increasingly unreliable precipitation. Cover crops have been shown to improve soil fertility and mitigate soil erosion in many regions, but are also associated with use of limited soil moisture, a cost that could mean decreased cash crop productivity for farmers. Most literature on cover crops comes from relatively humid climates, where crop yield penalties due to cover crops may be less pronounced.... L. Eash, A. Berrada, K. Russell, S. Fonte |
2. Dramatic Soil Health Changes After 18 Years of Different Nitrogen Rates and Cropping Systems in the Northern Great PlainsRelatively few long-term cropping and nitrogen rates studies have been conducted in the semi-arid northern Great Plains that assess soil health changes. A cropping system study was initiated in 2002 in Bozeman, Montana (~400 mm annual precipitation) with wheat grown in even years, and either tilled fallow or one of the following no-till systems in odd years: fallow, wheat, pea grain, pea hay, pea green manure, and an alfalfa-grass (until 2012) followed by pea grain. N was applied at either 50%... C. Jones, P. Miller, C. Zabinski, W. Fouts |
