First of all, buy a harvester, seeder, trailer, seeds, fertilizer, one small tractor, one SUPER tractor... since you definetly wink wink need it and a plow. Then you buy land and harvest the crops if there are any, if not you plant wheat or oat depending on the month and do that a couple of times until you can start with greenhouses etc and keep on expanding until you have a food monopoly in riverbend springs.
