If you want a rational basis for agriculture then minimum inputs is the

The farmer who owned the farm where I had a holiday in April, said only an idiot
uses more than the bare minimum of pesticides and fertilisers because they cost
so much.

There are enough idiots and illiterates around that cannot read the
instructions that it does happen. Some of the fruit sold domestically in
third world countries is the stuff that has failed pesticide residue
tests for export.
