Effects Of Optical Sensing And Variable Rate Technology On Nitrogen Fertilizer Use, Lint Yields, And Profitability In Cotton Production, Melissa Reynolds Stefanini
Effects Of Optical Sensing And Variable Rate Technology On Nitrogen Fertilizer Use, Lint Yields, And Profitability In Cotton Production, Melissa Reynolds Stefanini
Masters Theses
Nitrogen (N) fertilizer is expensive and can be harmful to the environment. Precision agriculture (PA) has the capability to reduce the amount of excess N from crop production released into the environment, increase net returns to the grower, and reduce the risk of profit loss due to spatial and temporal variability. The objectives of this study were to evaluate the profitability, risk management potential, and N use efficiency of using real-time optical sensing with variable-rate technologies (VRT) to manage spatial variability in cotton production. Data collected from 29 field trials in Tennessee, Louisiana, Mississippi, and Missouri from 2011 to 2014 …

Soil Test Information In Cotton Production: Adoption, Use, And Value In Potassium Management, David Caldwell Harper
Masters Theses
Soil sampling can help producers gain more accurate knowledge about soil nutrient properties and field-level characteristics. This information aids in the placement and timing of fertilizer application. Optimal input application may lower variable costs, increase economic returns, and moderate off-site environmental impacts of farming. Yet producer decisions to incorporate soil information into management practices and perceptions about the value of soil test information over time depends on a wide range of economic, social, and producer characteristics. Studies examining the value of soil information for optimal nutrient management may help inform producers considering adopting these technologies about the potential benefits of …
