1. Integrating Cover Crops and Livestock into Irrigated Cropping SystemsIntensive annual cropping consisting of barley-sugar beet rotations in irrigated systems could benefit from integration of cover crops and livestock. This research is being conducted on the University of Wyoming Research Station in Powell, WY, and on six farms in the surrounding area. This area has a short growing season and integrating cover crops into the cropping system is difficult. This study examines the implementation of cover crops after mid-summer barley harvest and... T.

2. Spoon-fed Nitrogen and Phosphorus Management for Subsurface Drip Irrigated Cotton (Gossypium hirsutum)Subsurface drip irrigation (SDI) is becoming a popular option for maximizing the water use efficiency of cotton (Gossypium hirsutum), especially in semi-arid environments of the Midsouth and Western United States. Applying fertilizers through SDI provides an opportunity to prescriptively apply nutrients at peak nutrient demand which could minimize loss and increase uptake, but the application timing is poorly understood. The objective of this study was to develop nitrogen (N) and... J.A. Burke, K.L. Lewis |
3. Nitrogen Management to Increase Cotton Production in Conservation Cropping SystemsThe use of conservation management practices, like cover crops and no-tillage, is common in semi-arid cropping systems to reduce wind erosion. However, the use of these practices can also reduce cotton lint yield. The purpose of this study was to determine the impact of nitrogen (N) management in conservation cropping systems to increase cotton lint yield. Two experiments were conducted at the Agricultural Complex for Advanced Research and Extension Systems in Lamesa, TX, USA. The first experiment... J.A. Burke, K.L. Lewis, J.L. Foster-malone |
4. Effect of 4R Nitrogen Management on Residual Soil Nitrate and Soil HealthNitrogen is one of the most important and expensive inputs for forage, grain, vegetable, and fruit crops. Excessive fertilizer reduces profit for farmers and can cause environmental harm. Nitrate leaching is the main factor contributing to rising nitrate levels in groundwater, leading to water quality degradation. The 4R nutrient stewardship framework aims to optimize fertilizer management. The Right rate matches the amount of fertilizer to the crop needs, the Right source matches fertilizer type... K.
