Searching For More Effective Corn Starters In Conservation-Till |
| Studies Show Urease Inhibitor Boosts Yields INDUSTRY AT WORK University and agribusiness studies affirm the beneficial effects inhibitors have in raising crop yields. (PDF, 2 pages, 43 KB) |
| Which Will It Be? Dr. Terry A. Tindall Drought and the talk of drought means we in agriculture must work to increase water-use efficiency through a better understanding of crop water use. (PDF, 3 pages, 21 KB) |
| Improving Nutrient Management Via Evolving Strategies and New Technologies Drs. J.S. Schepers, S. Payton, D.D. Francis, and J. Shanahan Nebraska studies focus especially on nitrogen and its impact on the environment. (PDF, 4 pages, 29 KB) |
| LATE SPRING |
| Using Starters to Reduce Broadcast Applications of P in Sugar Beets Drs. Albert L. Sims and Larry J. Smith Studies show P starters produced yields equal to or exceeding those produced by larger rates of P applied through broadcasting. (PDF, 2 pages, 20 KB) |
| Sensor-Based N Management Strategy Industry at Work New optical sensing variable rate application system improves nitrogen use efficiency and increases producer returns. (PDF, 2 pages, 28 KB) |

| Sulfur Applications Boost Alfalfa Yields Dr. Richard Koenig, kevin Heaton, and James Barnhill In sites marginal or deficient in sulfur, tests indicate that consistent responses to sulfur fertilization can be achieved. (PDF, 2 pages, 20 KB) |
| K In NP Starters Helps Bump Corn Yields Dr. Barney Gordon Three-year study shows that adding potassium can supply extra punch to push yields higher, even though soils already test high in P and K. (PDF, 2 pages, 19 KB) |
| FALL |
| Alternatives To Fall N Applications Via Fluids Dr. Gyles Randall and Jeffrey Vetsch Study looks at different application timing under two distinctly different corn tillage systems. (PDF, 2 pages, 21 KB) |
