1. Enhanced Efficiency Phosphorus Fertilizers Phosphorus (P) is essential for plants. However, first-year phosphorus fertilizer uptake by plants is low, resulting in economic and environmental impacts. Developments with P Enhanced Efficiency Fertilizer (EEF) sources show improved uptake efficiency and increased yield and/or crop quality, while reducing environmental risk. Research with EEFs (including organic acids, maleic itaconic copolymer, and struvite) all show these improvements, especially when: 1) soil test P concentrations are low,... B. Hopkins, S.J.

2. Static Range Nitrogen Management in Northwest U.S. Sugarbeet Production Nitrogen (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. Bjorneberg, D. Tarkalson, D. Olsen
3. Nitrogen Budgeting for Tree Crops In recent years, nitrogen (N) budgets and the 4 R’s approach (right rate, right time, right placement and right source) to N fertilizer management has been gaining more acceptance. In the N budget and 4 R’s approach, fertilizers are applied in proportion to demand and timed with periods of N uptake. As a result, demand is satisfied in a timely fashion avoiding the application in excess of uptake capacity. While N is required for all plant processes, it is the specific growth and development...

4. Lime Incubation for Southern Idaho Soils Soil acidity is a growing concern for agricultural productivity in Idaho, particularly in the eastern and northern regions where soils are trending acidic. Soil acidity below a pH 5.5 adversely affects the root development and nutrient uptake of crops like alfalfa, barley, and wheat. This study aims to determine the lime requirements for acidic soils in Idaho to optimize crop growth, specifically targeting pH levels of 5.5, 6.0, 6.5, and 7.0. Soil samples were collected from various grower fields... K. Young, J. Spackman, T. Jacobsen, J. Sagers, J. Hatch, R. Ritchie, J. Williams, K. Schroeder, A. Adjesiwor
5. Liming for Improved Nutrient Utilization and Weed Management in Wheat Soil acidification is an increasing concern for agricultural productivity in Eastern Idaho, where low soil pH threatens the yield and quality of key crops such as barley and spring wheat. Acidification occurs from the long-term application of ammonium-based fertilizers and other management practices, leading to aluminum toxicity and nutrient imbalances that inhibit root development and reduce yields. Farmers in the region are exploring strategies to address this challenge, including the use of... T. Jacobsen, J. Spackman, A. Adjesiwor, J. Sagers, K. Schroeder, J. Bevan, K. Mookodi, J. Gibbons
