1. Nitrogen Response of 2-Row Barley in North Dakota In about 2019, the major malting barley buyers moved from 6-row barley cultivars to 2-row barley cultivars. The N response of 6-row barley was well-established, however, little local data regarding 2-row cultivar N response was available. A 2-year study was conducted in North Dakota on two sites, using two cultivars at each site. Rates of N from 0 to 160 pounds N per acre were imposed on each cultivar. One site was in a long-term (30+ years) no-till system, while the other site was in a transitional... A. Wick, D. Franzen, B. Goettl Download paper
2. Snapshot of Crop Nutrient Balance with Use of a Rye Cover Crop in a Corn-soybean Rotation Under Tile Drainage in Eastern South Dakota The purpose of this study was to evaluate the effect of using a winter rye cover crop within a corn/soybean rotation (rye seeded every fall and burned down each spring) on drainage water quality, crop nutrient status, and grain yield. Use of a winter rye cover crop to take up available N from the soil profile is a management tool that may help to lessen nutrient movement out of the soil profile while at the same time contributing to improved soil health. Winter rye is very winter hardy... P. Sexton, S. Kumar, S. Osborne, B. Brockmueller, A. Bly, B. Rops, A. Bawa, S. Bauder, J. Mcmaine Download paper
3. Winter Wheat Response to Enchanced Efficiency Fertilizers in the Canadian Prairies Optimal nitrogen (N) management can improve agronomic efficiency, and increase winter wheat (Triticum aestivum L.) grain yield and protein content. Two experiments were conducted to measure the responses of winter wheat to enhanced efficiency N fertilizers and timing/placements across the Canadian Prairies. Experiment 1 consisted of uncoated urea, urea+nitrification inhibitor (urea+eNtrench®), urea+urease and nitrification inhibitors (SuperU®), and polymer-coated urea (Environmentally... Z. Wang, J.

4. Managing High-pH Soils: Restoring Nutrient Function with Polysulphate and Acidic Phosphate Fertilizers High 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
