1. Nitrogen Management in Small Grains After Alfalfa Small grains are commonly grown following alfalfa in Utah and the Intermountain West, especially during drought years as small grains require less irrigation than corn. Several studies across the country have shown that corn following alfalfa rarely needs N fertilizer, yet relatively few have evaluated the N needs of small grains. Furthermore, research on the N needs of small grains grown as forage vs. grain are even more sparse. The objectives of this research are to quantify the... C. Pound, M. Yost, E. Creech, G. Cardon, K.

2. Effect of Management on Nitrogen Budgets and Implications for Air, Soil, and Water Quality Nitrogen is a key nutrient for both national and global food security, and nitrogen inputs from organic and/or inorganic sources are essential to maintain sustainable and economically viable agricultural systems. The challenge with nitrogen is that it is very dynamic and mobile, and some forms are subject to biogeochemical transformations that contribute to atmospheric, surface and leaching losses. Although nitrogen provides important rural, national and global economic benefits, nitrogen losses... J. Delgado Download paper
3. Cover Crops for Nitrogen Management in Irrigated Cropping System In perennial fruit cropping systems, the inter-row offers on opportunity to grow a cover crop that then can be used to supply nitrogen (N) to the fruit crop. We conducted research in both Concord grape and Gala apple to evaluate the potential of cover crops to supply N to the crop. Based on continuous monitoring of plant available NO3-N by using PRSTM ion exchange resin probes, we found that in Concord grape, while both hairy vetch and yellow sweet clover did not release quite as much N as...

4. Comparison of Three Buffer Methods to Determine Lime Requirement in Columbia Basin Region of Washington State Weakly buffered soils of Washington State that have seen considerable pH change over the years due to use of ammonia based fertilizer products. Because these soils are weakly buffered and lime (CaCO3) requirement (LR) tests commonly report no lime is needed, a test that is sensitive enough for these conditions is preferred. Also, reagents used in some lime buffer methods are carcinogenic and/or toxic. A new buffer (Sikora) has been developed to work similarly to the commonly used SMP, but without... K. Bair
