The CRP can ruin your runoff. When 200 acres of farm land here in west Tx was taken out of cotton and put into CRP 20 years ago the 16 acre tank went dry and stayed that way. Land is now out of CRP and the tank is half full and stocked.
This is a big concern. My brother in law, out in KS has all warm season grasses above his pond, and it greatly reduced runoff.
I guess though, that grass cover has better runoff than crops. (From what’s posted above). I’ll see what the Mo Dept of Conservation guys say.
It would definitely help sediment from coming in, but in 7 years, I’m not seeing a whole lot of silting in. Lots of leaves, but that’s another story..
