1. Utilizing Food Processing By-products As a Soil Amendment: Soil Nutrient AvailabilityWe studied the impact of food processing by-products which contain high moisture content, low pH, high total dissolved salts, and trace elements. The primary goal of this project was to develop best management practices for sustainable reuse of food processing by-products as a soil amendment on California farmlands. Quantifying soil nutrient availability from these by-products is critical to growers to carefully establish fertilizer replacement value to improve their crop nutrient use efficiency... S.

2. Evaluating Potential Impacts of Land-applied Food Processing By-products on Soil Quality and Plant NutrientsFood processing canneries, especially those using raw fruit, nut, and vegetable- base materials, generate various types of by-products or non-hazardous wastes. The constituents of these wastes are dependent on the source of raw material and the substances associated with the canning processes. The use of land-applied non-hazardous wastes as an agricultural soil amendment is projected to rise because of public concerns regarding environmental impact and economic restraints of their disposal to...

3. Response of Soil N Cycling, Nitrifying Organisms, and Winter Wheat Yield and Quality to Nitrification Inhibitors in High Rainfall Zones of Northern IdahoLeaching of fertilizer nitrogen contributes to environmental pollution and is an economic loss for agricultural producers. Leaching of inorganic nitrogen fertilizers is intensified when applied to areas of high rainfall zones in excess of crop requirements. Reduction of this nitrogen loss may be achieved through the application of nitrification inhibitors at the time of planting to prevent the transformation of ammonia to more leachable nitrate by nitrifying organisms. Much research on nitrification... S. Philpott, H. Tao, K. Schroeder |
4. Lime Incubation for Southern Idaho SoilsSoil 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 WheatSoil 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 |
