1. Nitrogen Management and Budgets for Irrigated Cotton in the Western USAWe present research on new and improved and updated N fertilizer management recommendations for 4-bale/acre cotton based on a 36-inch NO3-N soil test for irrigated cotton from a 2-year study on surface/furrow irrigation study and a 1-year study under sprinkler irrigation. We also compared UAN with UAN plus the N loss inhibitor Agrotain Plus. Additionally, we compared reflectance- based N fertilizer management with soil test-based management. Nitrogen balances indicated that residual soil NO3 was... K. Bronson, J. Mon, E. Bautista, D. Hunsaker |
2. Soil Property Effect on Nitrogen Mineralization of Dairy Manure in the Pacific NorthwestGrowers 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 |
