Kenton, TN | I use Waters Lab for my soil sampling needs. The have software that will allow you to create a table that would show the over/under application of one nutrient when a blend is made from 2 products. In your case it would show how much zinc is over/under applied based on variable rate the phosphorus needs or it would give the opposite if you variable rate the field based on the zinc needs. I have used it a couple of times based on just P & K to decide which way would be best to variable rate a blend of DAP & POTASH. | |
