1. Evaluating the Trade-offs of Cover Crops in Dryland Wheat Systems of the Colorado Plateau On 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 Download paper
2. Rate and Depth of Liquid P Fertilizer Placement Affects Root Architecture and Arbuscular Mycorrhizal Fungal Associations in Grain Corn A two-site, two-year study was conducted on corn root response to liquid phosphorus (P) fertilizer applications as a function of rate and depth of placement. Corn planted into no-till at two locations (Thrall & Snook, TX) was fertilized with banded liquid P applied 15 cm off seed row at different rates and depths. The upper portion of the root systems were excavated along with all top plant matter at the V10 - V12 growth stage. Digital images of washed roots were analyzed for spatial density... J.
