1. Corn Yield Response to Sub-Surface Banded Starter Fertilizer in the U.S.Sub-surface fertilizer application at planting (i.e., starter fertilization) is a common practice in U.S. corn (Zea Mays L.) production to improve early-season nutrient uptake, nutrient use efficiency, and plant growth, especially under cool and moist spring soil conditions. However, yield increases from starter applications can vary across production systems and environments. Here, we use a meta-analysis approach to quantify and generalize corn yield responses to sub-surface starter... D. Quinn, C. Lee, H. Poffenbarger |
2. Adjusting Soybean Seeding Rate and Nutrient Strategies to Promote Nutrient Uptake in Irrigated and Non-Irrigated SystemsIncreases in total dry matter accumulation (TDM) can impact soybean (Glycine max L. Merr.) grain yield. However, the relationship between nutrient uptake and dry matter (DM) across seeding rates and influences on grain yield under irrigated and non-irrigated conditions remains uncertain. Two multi-year trials were established near Lansing, MI to investigate soybean dry matter accumulation, partitioning and remobilization; nutrient accumulation, partitioning, and remobilization; grain...

3. Nitrogen source and application timing for corn to mitigate leaching and gaseous N lossesNitrogen (N) is an important nutrient for corn, but N fertilizers are associated with contamination of surface waters through leaching and gas emissions through denitrification and volatilization. A comprehensive N loss study was conducted at the University of Minnesota Southwest Research and Outreach Center (SWROC) in Lamberton, MN from 2014 to 2020. The objectives were to quantify the effects of traditional (pre-plant urea) and advanced N management practices (split-N applications and... |
4. Banding Nitrogen Increases Nutrient Uptake and Yield of CornInadequate nitrogen (N) availability during the start of the corn (Zea mays L.) growing season can reduce the yield potential of the crop. However, the greatest amount of N is required during the period of rapid growth (from 10-leaf stage to tasseling [VT]). Banding N at or near the time of panting increases availability of N to the corn plant and could allow for the reduction in early-season N rates without reducing yield potential. Across the state of Illinois in 2019, urea ammonium nitrate... E.T. Winans, F.E. Below |
