1. Belowground Ecological Interactions For Improved Plant Health, Nutrition And Environmental Quality In Agricultural Production Plant roots are in constant interaction with the myriad of organisms that inhabit the soil. Microbe-root associations are important for a plant’s successful establishment in an environment as they directly or indirectly support nutrient cycling, nutrient uptake and defense from abiotic and biotic stressors. Therefore, managing these interactions offers a great opportunity for improving the efficiency and sustainability of agricultural production by improving plant nutrient uptake,... C. Lazcano, E. Boyd
2. Test Driving a New Nrcs Nutrient Budget Calculator for Nutrient Management Planning in California In executing its mission to aid landowners in making conservation improvements, the USDA-Natural Resources Conservation Service (NRCS) assists landowners in identifying their operation’s potential risks to natural resources, if any. For assessing a cropland producer’s nutrient management, determining whether their nutrient applications rates might be considered excessive or has a potential to load up soil levels is key. However, NRCS does not make prescriptive nutrient... B. Gale, Z. Kabir Download paper
3. Applying a Phosphorus Risk Index in a Mixed-use Mountain Watershed Surface waters in the Wallsburg, UT watershed have been identified as a relatively high contributor of phosphorus (P) to nearby Deer Creek Reservoir. Identifying the major contributors of P is critical for developing effective management practices. Phosphorus Risk Indices have been widely developed as a tool to identify areas with high risk of P movement, but these tools have mostly been applied to watersheds dominated by agricultural land use. While agriculture is often a source of nutrient pollution,... A.W. Pearce, J. Johns, D. Robinson, N. Hansen Download paper
4. Economics of Fertilization Under Site-specific Management Zones Site-specific management of crop fields using variable rate application of inputs to manage in-field variability has now been around for over 15 years. However, the degree to which site-specific management strategies increase farm profitability is not well established. The objectives of this study were: to compare uniform and variable-rate Nitrogen (N) management strategies across productivity level site-specific management zones and to identify the most profitable N management strategy. This... R. Khosla, D. Westfall, W. Frasier, B. Koch Download paper
