Our place is so flat, I don't think we lose any soil during wet periods, at least not from the field. The only place I see any kind of silting is in the slough on the north side of our property, but there's plenty of current in there as its an offshoot from the main channel of the Lemonweir River. When our field floods, its just due to the main channels and offshoots overflowing their banks and entering into old oxbows, potholes, marshes, etc and then those back up into our field eventually.
We aren't enrolled in anything, but the 40 that the field is part of is zoned Ag so taxes are minimal. The 40 to the east of us, which is purely recreational is taxed double basically.
Someday I'd like to take the SW quadrant of our field and make a kidney bean shaped pond or wetland scrape, surrounded by willows/poplars, and a block of nwsg in the very SW corner. This would leave an L shaped field of about 3-4 acres and it would be more insulated from the road. My poplar screens have helped with that somewhat but it's not a complete screen.
