1. Cover Crops in Semi-arid Dryland Winter Wheat (Triticum Aestivum, L.) Fallow Rotation, a Farmer Collaboration StudyWinter wheat (Triticum aestivum, L.) (WW) is a primary dryland crop in semi-arid southeastern Wyoming. Incorporating cover crops (CC) to a WW-fallow rotation can help improve soil health. Local producers have been exploring the possibilities of using CC, but little is known about the CC impacts on soil moisture, plant available nitrogen (N) and competition with weeds in this region. A collaborative study with two dryland organic WW producers was launched in 2020. FARM 1 was planted to a CC mi... E. Moore, U. Norton |
2. Soil Properties and Winter Wheat Nutrient Uptake As Affected by Long-term Tillage and Nitrogen FertilizationKnowledge gained on the long-term effects of crop management practices on soil fertility is critical in developing nutrient management strategies to optimize crop yields and environmental sustainability in semi-arid cropping systems. This study examined the long-term effects of nitrogen (N) fertilizer management and tillage intensity [conventional tillage (CT), and no-tillage (NT)] on soil properties and nutrient uptake in a dryland wheat-sorghum-fallow cropping system. Results showed winter ... A. Obour, J. Holman, L. Simon, Y.M. Assefa |
3. The Paradoxical Pursuit of Sustainable Nitrogen Management in Irrigated High-Elevation Hay MeadowsIrrigated hay meadows are an integral, but often under-performing component of livestock operations in the Mountain West. Saturating irrigation and cool temperatures result in buildup of organic matter in form of an O-horizon, hindering forage production and nitrogen (N) cycling. For these reasons, many ranchers choose to fertilize with N regardless of large stores of N already in the soil. To improve long-term forage production in meadow systems, it is therefore critical to understand t... D. Adamson, J. Norton, U. Norton, L.T. Van diepen, M. Singh |
