Unfortunately these are the practices that are destroying our topsoil by trading soil health for short term profit.
Often these are the same farmers that ignore the much needed soil tests that
@WAB mentioned, and simply throw out hundreds of pounds of 20-20-20 per acre; while complaining about fertilizer cost.
We do have problems with improper fertilizer use in the USA and runoff from it is a major factor in why so many of our lakes and streams are choked with vegetation.
Example: Nitrogen in granular form is a volatile element, if you spread hundreds of pounds per acre at one time your probably losing 50% of it to runoff and evaporation and if your soil PH is to low your only getting 50% of the fertilizer value being applied.
I’ve seen soil tests for Bermuda grass & corn requiring 800lbs + per acre of nitrogen alone.
