1. Estimating Nitrogen Credits from Organic Matter Sources in OrchardsOrchard crops like almonds can effectively utilize different nitrogen (N) sources to meet the high annual N demand for fruit and tree growth. Different fertilizer formulations like urea ammonium nitrate, calcium ammonium nitrate, ammonium sulfate and potassium nitrate are widely and effectively used, and readily available for uptake. Yet, addressing N availability from organic matter sources in orchards, and in turn estimating appropriate N credits... S.S. Khalsa, P.H. Brown |
2. Integrating Cover Crops and Livestock into Irrigated Cropping SystemsIntensive annual cropping consisting of barley-sugar beet rotations in irrigated systems could benefit from integration of cover crops and livestock. This research is being conducted on the University of Wyoming Research Station in Powell, WY, and on six farms in the surrounding area. This area has a short growing season and integrating cover crops into the cropping system is difficult. This study examines the implementation of cover crops after mid-summer barley harvest and... T.

3. Creating Prescription Variable Rate Irrigation and Fertilization Zones: Water and Nutrient Management InteractionsVariable rate irrigation (VRI) and variable rate fertilization (VRF) technologies allow irrigation and fertilization rates to be spatially customized. VRF is widely adopted, but VRI is an emerging technology with minimal adoption. As water is often the driving force in nutrient cycling, our overall objectives are to evaluate VRI influences on VRF and vice versa; and to combine these technologies to significantly increase crop yield and quality, conserve water, and minimize environmental impacts...

4. Development of Leaf Sampling and Interpretation Methods for Almond and Development of a Nutrient Budget Approach to Fertilizer Management in AlmondA five year research project on the use of N in orchards crops has been conducted to 1) to develop early season sampling protocols, and 2) to determine the response of Almond to various rates and sources of nitrogen (N) and potassium (K) fertilizers, 3) to develop nutrient demand curves and 4) to conduct a long term assessment of nutrient use efficiency with the goal of improving fertilizer management. Leaf and nut samples were taken at 5 stages of development throughout five seasons to determine... P.H. Brown, S. Saa, S. Muhammad, B. Sanden |
5. How Variable is Variable for Production Fields in Southern Idaho?Idaho ranks in the top 10 in the US for dairy, potato, barley, hay, sugar beet, corn silage, and dry bean production. The highest producing areas in the state for these commodities are in Southern Idaho. Agricultural producers in this region, just like many other regions, are tasked with managing irrigation water and soil fertility on large fields with spatial heterogeneity in a way that results in homogeneous crop production. Management... L. Schott, C. Robison, E. Brooks, D. Bjorneberg, K. Nouwakpo |
6. What is a Plant Nutrient? Changing Definitions to Advance Science and Innovation in Plant NutritionWe propose a new, more comprehensive definition of mineral plant nutrients that extends beyond the current narrow criteria. This expanded definition encompasses not only essential elements but also those that are beneficial for plant growth, development, or quality attributes across various species and environments. The proposed definition recognizes elements with clear metabolic functions and those that enhance plant productivity, crop quality, resource use efficiency, stress tolerance, or pest... P.H. Brown |
