I am looking at a farm to purchase and had a few questions for the farmers out there. 78 acres, 53 in CRP for one more year (one more $5300 payment coming this fall), asking $2740 an acre in eastern Iowa. Its been in CRP for 20 years and I was told by the assessors office it has an average CSR of 44. I was suprised by the CSR number because the county average is 81. Can this number change because its been in CRP for so long or is it strictly based on soil type? To those who have experience with this kind of thing do you think the numbers add up? Dont know if I would rent it or share crop it yet.
