1. Foliar Fertilization of Soybeans in MissouriSoybeans may benefit from foliar fertilization during the reproductive phase of growth. Foliar fertilizers consisting of factorial combinations of boron, calcium, magnesium and phosphorus were applied to soybeans every other week for eight weeks beginning at flowering at three locations. The foliar fertilization treatment containing B+Mg (1.0 lb/acre B + 2.0 lb/acre Mg total) and split into four applications at Mt. Vernon and the Delta Center increased yields by 8 and 4 bulacre, respectively. The... |
2. Phosphorus Fertilization Improves the Quality of Stockpiled Tall FescueStockpiling tall fescue is a recommended practice for increasing profitability of beef cattle production. However, little information is available on the mineral element composition of tall fescue pastures stored for winter grazing. In fact. analysis of the few studies reported indicates that both phosphorus and nlagnesium levels may be low in stockpiled tall fescue by late winter. The objective of this study was to determine the impact of phosphorus fertilization on improving the nutrient quality... |
3. Active and Passive Spectral Sensing for Predicting the Optimum Nitrogen Rate and Timing in CornThere are many in-season plant diagnostic tools available for predicting the rate and timing of in-season nitrogen fertilizer in corn (Zea mays L.). However, soils in Southern Minnesota are generally high in organic matter and can carry over nitrate- nitrogen from one season to the next. Subsequently, there is oftentimes sufficient soil nitrogen early in the growing season to supply much of the crop requirement, limiting the use of sensor-based N management tools. Past work... T.
