1. A Comparison of Producer Adoption of Precision Agricultural Practices in Denmark, The United Kingdom, and Nebraska in the United StatesWhile a lot of research and commercial development has taken place in precision agriculture in recent years there is little information available about the experience and opinions of the producers who are trying to make it pay its way in the field. Information about producer experiences in precision agriculture would be useful in guiding hture research and development in both the public and private sectors. Important questions could include: - what types of precision agriculture practices are producers... |
2. Early Season Nutrient Uptake from Combinations of N itrogen, Phosphorus, and Potassium Applies in Starter Fertilizer in Two Corn HybridsConventional small plot field trials were establ ished to study the effect nitrogen (N), phosphorus (P), and potassium (K) applied as starter ferti lizer on early season growth and nutrient uptake of two corn hybrids with a nd without the Bt-rootworm gene. Ei ght locations were studied over two years comparing a non-starter check, N only, K only, NP, NPK, and NK starter fertilizer combinations on early season growth and nutrient uptake. Sites tested High initially in both P and K. One or more starter... |
3. Soil N2O emissions in continuous corn as affected by 4R and cover cropsCover crops and 4R nitrogen (N) management are promoted as key practices for reducing nitrate leaching losses, but their impacts on nitrous oxide (N2O) emissions remain less certain. This study evaluated soil N2O emissions and grain yield under different timing of N application and cover crops for two years in a tile-drained continuous corn system. Treatments were 224 kg N ha-1 split-applied in fall + pre-plant (Conventional), pre-plant + side-dress (4R), 4R +... G. Preza fontes, L.E. Christianson, C.M. Pittelkow |
