"The 2014 Farm Bill ratchets down CRP’s total acreage cap over five years from its current statutory level of 32 million acres to 24 million acres, though this in and of itself is not a major loss. To a significant degree, this reduction tracks changes in CRP enrollment expected as a result of market forces, though with the declining cap the opportunity for new general sign-ups would be relatively small."

I would analyze this as saying that its going to be very difficult to renew contracts on anything but the most fragile acres, and next to zero on anything that is not currently in CRP.
