It does surprise me this topic hasn’t come up before. From where I’m sitting, the income is similar to a rental unit (and the taxes, lower), without all the headaches, cost and maintenance those things bring. It may not be quite as lucrative, but it’s entirely passive. CRP is a bit more work; for what I'm looking at it would be an occasional burn.
I've been renting out for corn/soybeans for a number of years with no complaints, albeit at lower rental prices than the avg since my soil is so-so. However, a neighbor recently turned me onto the CP-42 program which is native grasses/wildflowers (a quick google will bring up the brochure). 10-year commitment, $150/acre signing bonus, competitive cash rent pricing and 50% cost share for establishment and maintenance. I checked with the FSA last week on only doing a few acres, but after a quote and further investigation, might just do the entire thing. A local quote to have it planted (takes a special drill) was $50/acre + seed. Seems like a no-brainer right now.
