Soil Test Interpretation
This program provides fertilizer rates to meet the crop nutrient needs based on soil test results. The program will analyze the gross return based of commodity prices and fertilizer costs for P and K applications. It also calculates the value and application rates of animal manure as a nutrient source for specific field conditions.
It requires Java Web Start to run the program. If this is your first time to use it, please check Overview and Installation before you run the program.
