I would think you'd have to pretty well versed in the farming business and the local business conditions, not just someone new to it all. Having a background in that would help immensely. Is that your situation?
I would also be very hesitant to count on appreciation, just as I am with tenant rental properties. I require positive cash flow first (at 100% financing, with provisions for vacancy and maint), price appreciation is a bonus.
Are there actually any land parcels where the rents provide a decent Cap rate? My understanding is that most such parcels are held by speculators, not investors, and that rental income is just used to offset some of the cost. They hold many properties for diversity, and 1 in 10 might take off in price and give them a decent overall return.
I do have some small background in this, with a family hobby farm. My understanding is that a bush property is generally a better investment. You can select log the valuable hardwoods to sell to artisans and fine manufacturers, and do more general logging for firewood. A family member does this currently, cuts, bags, and sells wood to sell to stores that serve campers in summer.
