1. Impact of Nitrogen Fertilizer Source and Application Date on the Yield and the Quality of Winter WheatNitrogen (N) is one of the most important and critical nutrient elements in agricultural systems, and its effect directly affects crop productivity and nutrient content. Our field studies were related to the wheat Crop. They were conducted in four locations to evaluate the effect of various Nitrogen sources (SuperU, Urea, UAN and UAN+Anvol) applied at three different times (pre, greenup and jointing). The experimental design of the four locations was randomized complete with... H. Moulay, B. Arnall |
2. Comparative Analysis of Different On-the-Go Soil Sensor SystemsThis study is part of the field of precision agriculture. This management mode is one of the great revolutions in the agriculture field, and it means better management of farm inputs such as fertilizers, herbicides, and seeds by applying the right amount at the right place and at the right time. Precision agriculture aims to divide the farm into management plots where each receives customized management input based on soil fertility status, landscape position, and management. also provides...

3. Managing High-pH Soils: Restoring Nutrient Function with Polysulphate and Acidic Phosphate FertilizersHigh soil pH often reflects the active consumption of hydrogen ions (H⁺) by carbonates and bicarbonates, which suppresses calcium solubility and reduces the availability of phosphorus, potassium, and key micronutrients. These limitations are driven by soil chemistry rather than true nutrient deficiency, restricting nutrient mobility and root access. This presentation will examine Polysulphate® as a functional calcium and sulfate source that improves system efficiency. In addition, ICL... A. Foster, J. Hagele, T. Donoho, D. Tollefson |
