1. Soil Acidification of Cultivated Fields in Semiarid Montana: Adaptation and Challenges to RemediationHistorically, soil acidification was not a problem in Montana because the parent material of most cultivated soils exhibited a neutral to an alkaline reaction. However, fertilizer ammonium‐N use (including urea) by farmers has grown tremendously in recent decades contributing to leading to a downward trend in soil pH and with incidences of soil acidity/Al toxicity now beginning to appear. Here we summarize the results from on-farm sugar beet lime trials to remediate soil acidity; seed-placed... R. Engel, C. Jones |
2. Evaluation of E-Grow Effects on Soil Plant Systems Gas ExchangeE-Grow is a novel fertilizer which effect on the soil- plant system is critical for understanding it’s impact on the crop productivity and environmental sustainability in agricultural operations that will be crucial for updating nutrient application recommendations, to understand this we conducted an experiment with the main objective of this study is to determine the effect of E-Grow on CO2 and H2O fluxes in agricultural soil and soil- cotton plant systems (seedling stage). This experiment... V. Sabbineni, E. Enninful, S. Jacobo, O. Gecgel, G.G. Botte, H. Laza, C. Simpson, L. Slaughter, Y. Emendack |
