1. Soil Acidification: Identification, Prevention, Adaptation and RestorationLow soil pH is becoming far more common in Montana soils, with at least 23 counties having at least one field with pH less than 5.5. Soil pH levels in the top 6 inches as low as 3.8 have been measured, resulting in complete crop failure insome locations, yet the problem is highly variable across fields and within soil profiles. Nitrogen fertilizer rates applied above crop nitrogen needs are the largest cause of the acidification. Low soil pH should be verified before managementpractices... C. Jones, R. Engel, S. Ewing, P.

2. Effect of Cover Crops and Compost on Soil Water Availability in Organic Dryland WheatIn low input semi-arid regions, water is the major limiting factor in crop production. Cover crop biomass and compost are good source of organic matter, that improve biological activity and water holding capacity of soils. However, dryland organic wheat growers rarely apply soil amendments due to cost and cover crops can lead to the depletion of soil water which decreases the yield of subsequent winter wheat. This study investigates the potential for a synergy between compost addition and cover... K. Adeleke, J. Reeve, E. Creech, I. Atoloye |
3. Phosphorus and Zinc Interactions in PotatoPotato production requires high soil phosphorus (P) application with potential negative environmental and nutrient uptake effects. Impacts of high available P on species in potato cropping rotations are not adequately understood, nor have the causes of reduced yield and quality from excess P been fully explored. Antagonistic interactions with cationic micronutrients such as zinc (Zn) are plausible explanations. Two hydroponic experiments were conducted with Burbank potato to elucidate P and Zn... B. Webb, B.

4. Micronutrient Management to Optimize Yellow, Brown and Oriental Mustard Production in Southern IdahoOilseed crops hold a significant position in global agriculture, serving as vital sources of essential oils and as raw materials for numerous industries. Among these, yellow, brown, and oriental mustard are prominent for their multifaceted uses, particularly in the culinary and industrial sectors. However, these mustard varieties face challenges in achieving their maximum yield potential, largely due to suboptimal nutrient management practices. Fertilizer programs, though essential for productivity,... H. Ali, J. Spackman, J. Pandey |
