I am a farmer and yes I have some CRP ground. Usually it is the waterways or the edge of the ditch where they want a buffer or filter strip to keep fertilizer and herbicides from getting into the surface water.
For the record, I was never paid by the government to refrain from making software in order to keep the software supply artificially low so that my fellow hard working family programmers could stay in business.
The government sure doesn’t mind dumping thousands of gallons of liquid manure into the surface/ ground water and contaminating it.
