1. Denitrifying Woodchip Bioreactor Performance in the Pacific Northwest Runoff and tile drainage from agricultural activity is known to be a significant contributor of nitrogen pollution to surface waters. Denitrifying woodchip bioreactors, also known as Permeable Reactive Barriers (PBR) have been studied as a possible edge-of-field technology for reducing nitrogen concentrations in agricultural runoff. These units have been studied mostly in the US Midwest and mostly for irrigated crop systems. Little work has been done in alternative climate regimes... E.M. Weisshaar Download paper
2. Effects of Lime and Micronutrient Amendments for Acidic Soils of the Inland Pacific Northwest The soil pH of agricultural land in the inland Pacific Northwest has dropped precipitously from native soil levels of near 7.0 pH. Changes that were becoming evident in the 1980’s have reached critical levels, leaving tens of thousands of acres of previous prairie soil at pH under 5.0 and unable to grow an increasing number of aluminum-sensitive crops. Some farmers in the region are beginning to use lime application to neutralize soil acidity. However, pH changes and liming can also... R. Wieme, L. Carpenter-boggs, P. Carter, S. Van vleet Download paper
3. Reuse and Reclamation of Phosphogypsum Phosphogypsum (PG) is a byproduct of phosphate fertilizer production. It is produced when phosphate rock is treated with sulphuric acid during the manufacture of phosphoric acid, and is composed primarily of gypsum (CaSO4.2H2O). It is estimated that over 3 billion tonnes of PG have been accumulated in stacks worldwide and over 150 million tonnes are produced annually. In North America, PG is stockpiled in stacks that can cover hundreds... C. Nichol Download paper
4. 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.

5. Stacking 4R Nutrient Management: Potato The 4Rs of nutrient management are research-based guidelines with the aim to improve the sustainability of major cropping systems and the environment without compromising crop yield and quality. The term “4R” represents fertilizer applied at the Right rate with the Right source, Right timing, and Right placement. The objective of this project is to evaluate the interactions of individual and combined 4R management practices. In 2020, potato (Solanum tuberosum L.) was grown... S.H. Stapley, C.C. Whitaker, N.C.
