I understand that the landowner can put whatever stipulations he feels in the contract (ie. fertilize, irrigation, maintenance etc.). When it crosses the line into essentially taking a share of the crop through bonus payments then FSA will look more closely at who is drawing the money and how the crops are divided to make sure they match. This probably won't present a problem but it would be worth checking out before making a mistake that could have dire consequences. I know it would be a reach but this could be construed as a way to get around payment limits or the 3 entity rule if the landowner draws payments from several different farms. I've probably got a little different perspective on this because I deal with a couple different owners who are nearing the payment cap and are looking for legal ways around it.
