1. Nitrogen Balances in Dairy Production Systems in Southern Idaho Nitrogen (N) is essential for agricultural production, but excess quantities can be detrimental to both water and air quality. The increase in dairy cattle populations in the Magic Valley of southern Idaho has lead to concerns over the impact of N losses to the environment and the impact on both water and air in the region. This work examines the N flows and balances at the production facility, whole farm and regional scale. At the production facility, approximately 60% of N imported was lost... A. Leytem Download paper
2. Reducing Nutrient Losses in Runoff from Furrow Irrigation Few studies have comprehensively examined nutrient losses in runoff from furrow-irrigated fields, but the rising cost of fertilizer and finite nature of the resource encourages further research. A 2-yr experiment measured runoff losses of sediment, particulate P and N, and dissolved NO3-N, NH4-N, K, and reactive P (DRP) from fertilized, manured, or non-amended fields. Average nutrient losses were substantial, including 15.6 lbs ac-1 yr-1 dissolved N, P, and K and 73.6 lbs ac- 1 yr-1 particulate... R. Lentz, D. Westermann, G. Lehrsch Download paper
