1. Test Driving a New Nrcs Nutrient Budget Calculator for Nutrient Management Planning in CaliforniaIn 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 |
2. Effects of Commercial Organic and Cyanobacterial Fertilizers on Instantaneous Water Use Efficiency in Drip Irrigated Organic Sweet CornWater and fertilizers are applied to maintain crop growth, yield, and quality. Nitrogen (N) fertilizer plays a crucial role in crop growth and yield development of sweet corn (Zea mays). Organic growers often use commercial organic animal- based fertilizers which vary in nutrient composition, forms of available N (NH4+- N and NO3--N), and have high transportation costs. Alternatively, cyanobacteria can be grown on-site as a source of N. Cyanobacteria haves unique dual properties because they... J. G. davis, A. Sukor, C. Ramsey |
