1. Economic Perspective on Variable Rate FertilizationSoils form a continuum across every farmer's field, constantly changing in both physical and chemical characteristics. Sometimes these changes are visible; sometimes they are completely masked to the eye. Variables such as organic matter, water-holding capacity, pH, and soil nutrient levels differ, and combined, they affect crop yield goals. In either case, these differences should result in different management practices, including fertilizer applications, being recommended for different soils within... |
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. Exploring the Impact of Temporal Variability in Emergence on Corn Grain Yield and Development PatternsConcerns have raised among farmers in the Midwest regarding the impacts of uneven emergence of corn (Zea mays L.) seedlings. Research has showed that even a minor delay in emergence of a few hours could have a substantial influence on plant performance and ear weight; and one of the contributing factors to uneven seedling emergence in corn is the application of starter fertilizer. Placing fertilizers in the seed furrow increases the salt concentration surrounding the seed and as a result, delays... L. Dorissant, P. Kovács, J. Clark |
