Tenant farming. Tenant farming is a good option if you have access to the equipment necessary to plant, maintain the crops as they grow with fertilizers, herbicides and the necessary pesticides, and harvest. Depending on the size of the fields, you may need to have a sizable cash reserve or access to credit before you plant. Again, do your homework so you can be sure that you can settle your debts and actually reap some profit. In some tenant farming situations, your landlord may provide some supplies in exchange for a percentage of the crop.
