1. Enhancing Alfalfa Production Through Improved Phosphorus and Potassium ManagementAddition of phosphorus (P) and potassium (K) fertilizer is vital to maintain alfalfa productivity. The objective of this study was to examine how P and K fertilizer application increases alfalfa yield. nutrient use, and plant persistence. Replicate plots of P (0, 50, 100, 150 1bs P205/acre) and K (0. 100, 200, 300, 400 Ibs K20/acre) treatments were arranged in a factorial design. Forage harvests occurred four times annually for 5 years and yield, mass per shoot, shoots per area, and herbage nutrient... |
2. Predicting Relative Yield of Corn in Indiana Using an Active SensorFine-tuning N fertilization is important for impr oving the economic and environmental impact of corn production. This importance is highlighted by ever rising fertilizer prices and increased public scrutiny. Reflectance measurements usi ng an active sensor during the growing season may be useful for determining the need for additio nal N. This is the second year of a multi-year study to evaluate canopy reflectanc e as an N management tool across a variety of Indiana soil types. The objectives of... |
