Drop a pin to your field and fill in some necessary information (e.g., soil type, tillage, and other management). For each of the four fertilizers (four different N-P-K-S-Zn formulas), you will be able to choose a range of values you want to test (e.g., 0-800 lb/ac of every product). Then, the yield of all combinations among all practices will be compared against your typical cropping system choices.
This tool performs economic analysis. Two cropping systems will be generated, one for maximum yield and one for maximum profit.
Make sure you have the following before you start:
1) Fertilizer cost ($ per ton of each product)
2) Applying Nitrogen fertilizer is not free (e.g., extra fuel cost) so we need an estimate of application cost ($/ac)
