1. Induced Manganese Deficiency in GM SoybeansGlyphosate resistance in soybean and corn reduced manganese uptake and physiological efficiency. Applicatior~ of glyphosate immobilized manganese applied before, concurrent with, or within 6-8 days after the glyphosatc event. Inorganic sources of manganese (Cl, CO,, SO,) tank-mixed with gly-phosate were antagonistic and reduced herbicidal efficacy: ho~vever, antagonism was significantly influenced by glypllosate fonnulation. Glyphosate root exudates and plant deconlposition products can alter the... |
2. Using Reflectance Sensors to Predict Nitrogen Needs of CottonObjectives 1) Develop on-the-go N recommendations based on analysis of the reflectance sensor readings. 2) Determine the sensor model, height, and wa velength that give the best prediction for sidedress N. 3) Determine the best growth stag e for sensor-based sidedressing Relevance There is great spatial variability of N in the soil. Cotton fields that receive a blanket rate of nitrogen, ignoring the vari ability, will have areas of excessi ve growth. This unnecessary growth raises production cost... |

4. Nitrogen Timing Fertilization Strategies for Winter Wheat in WisconsinEconomically optimum winter wheat (Triticum aestivum L.) production relies on effective N application rate and timing. Previous research in Wisconsin indicates a need to better understand winter wheat response to N rate and application timing for growing conditions specific to the state. This study evaluated the effect of N application timing on yield, economic optimum N rate (EONR), agronomic N use efficiency (NUE), and profitability. A three-year study was conducted at three locations... J.D. Jones, C.A. Laboski, T.W. Andraski |
