This guide is a systematic reference on agricultural finance. Part 1 covers security interests in crops, livestock, equipment, and program payments, and the statutory liens that compete with them. Part 2 covers the farm products rule and the two notice mechanisms that defeat it. Part 3 covers federal crop insurance — coverage structures, production history, and claims. Part 4 covers disaster programs and their interaction with insurance. Part 5 covers family farmer bankruptcy from eligibility through discharge. A final part collects the annual calendar and the failure modes that recur.
