1. Variable Rate N and P Management for High-value Vegetable Cropping Systems The Lower Colorado River Region (LCRR) of Arizona and California and their environs produce more than 90% of the nation’s cool season vegetables during the fall-winter-spring period. Large amounts of N and P fertilizers are currently utilized for maximum yield and quality. Phosphorus fertilizers are applied pre-plant based on a soil test of a composite field sample. Nitrogen is applied by side-dress based on a plant midrib or petiole N analysis, or soil nitrate-N test, from a... C.A. Sanchez, P. Andrade Download paper
2. Soil Property Effect on Nitrogen Mineralization of Dairy Manure in the Pacific Northwest Growers often use total nitrogen (N) concentration of dairy to manure to estimate plant available N for crop production. This estimate, however, ignores the role that soil properties may have on N mineralization (Nmin) rates. This study aims to determine how soil physiochemical properties impact Nmin rates of dairy manure and composted dairy manure by aerobic incubation. Sixteen soils, sampled from 0-12 inch depths (0-30.5 cm) were collected from dairy production regions in Oregon, Washington,... R. Auld, A. Moore, J. Moore, Y. Zhang, C. Rogers
