I was hoping you'd get more response. Me participate? No. But I do see a lot of activity and where it sometimes goes bad. I guess you have already determined you are qualified to apply? A lot of the benefits and practices are designed to improve conservation on cropland in production. There is a wildlife component that makes this attractive to non-farming landowners.
It is a two-party deal. After you and your local conservationist agree on practices and programs you have an obligation to implement and maintain them under the contract terms. It's a five year contract. Then, you own it.
Funds are limited and you may be placed on a waiting list that never ends.
A lot of people think they are going to get money and do whatever they want. You may never be spot checked, but be prepared for it. Some states and localities are more involved than others. Most all NRCS folks I know are very considerate of your 'property rights,' but you do agree that NRCS can enter your property at anytime with or without your knowledge and consent. Like I said, you'll probably never see anyone.
Having said all of that, most everyone I know in the program is extremely happy.
