Fertilizer Removal by Crop app

It is a great guide to know exactly what types of fertilizers I should use and the yield I want to get.

Excellent app with lots of reference information for the amount of vital nutrients for the corn crop.

This app lets me enter my own yield and it instantly helps by giving the removal rates. Really helpful. I just wish it doesn't crash as much as it does. Does less harm than good but would want it to be updated much better. Support helps but they can only do so much. This app needs better updates!
