1. Alfalfa Contributes More Nitrogen to Following Crop Than Previously Thought Alfalfa in high-yielding environments fixes significant amounts of atmospheric N2, a portion of which benefits succeeding non-legume crops and reduces fertilizer N requirement by an amount sometimes called the “legume N credit”. Field research-based estimates of the legume N credit in California and other irrigated, semi-arid or arid environments are sparse in the literature. We conducted replicated plot experiments at three field station sites in California using wheat as an indicator... S. Pettygrove, E. Lin, D. Putnam, M. Lundy, S. Orloff, S. Wright Download paper
2. Demonstration of Veris Nir Soil Carbon Mapping Technology The new VERIS Technologies Near Infra Red (NIR) Spectrophotometer compares soil spectral measurements with soil carbon (C) and other properties. These data can be utilized to generate maps of soil characteristics across the landscape. This potentially useful system may simplify the measurement of important soil properties, provide a new tool for evaluation of residue conservation management practices, and guide farmers in soil management decisions based on data heretofore unavailable. While growers... P. Carter, S. Van vleet, E. Perry, S. Young, F. Pierce
3. Nitrogen Cycling and Partitioning Under Alternative Organic Orchard Floor Management Strategies Organic orchard systems are a significant and growing component of Washington State agriculture, yet sustainable methods of nitrogen (N) fertility and weed management remain a challenge. Nutrient supply is dependent on decomposition and mineralization of organic matter, yet intensive cultivation commonly used to control weeds can disrupt biological processes and cause loss of organic matter. To address the often-competing goals of organic fertility and weed control, a number of alternative orchard... L. Carpenter-boggs, D. Granatstein, J. Reganold, L. Hoagland, M. Mazzola, F. Peryea, J.
