1. Static Range Nitrogen Management in Northwest U.S. Sugarbeet ProductionNitrogen (N) management is important in sugarbeet production. This paper presents data to support a shift from a yield-based N management approach to a static range N management approach in the Northwest U.S. Production data and research show that yield-based N management can result in over application of N. Past research has been critical to improving and understanding sugarbeet N nutrition. However continued research is needed so cumulative data can be evaluated to improve management practices.... D.

2. Approaches to Nutrient RecommendationsScientific based crop nitrogen (N) fertilizer recommendations are vital to guide N management within the agricultural sector. Accurate recommendations can maximize producer economic returns and minimize losses to the environment. Obtaining accurate recommendations is a dynamic process that requires constant research to update recommendations (within current scientific knowledge) and to better understand soil N cycle processes (develop new scientific knowledge) that can further improve...

3. Irrigated Small Grain Residue Management Effects on Soil Properties and Nutrient CyclingThe effects of straw removal from irrigated wheat and barley fields on soil properties and nutrient cycling is a concern due to its potential impact on the sustainability of agricultural production. The demand for animal bedding and the potential development of cellulosic ethanol production will likely increase straw demand in the future. Previous reviews addressing changes in soil properties when crop residues are removed focused primarily on rain-fed systems. This paper reviews published research... D. Tarkalson, B. Brown, D.
