There are literally dozens of rotations that might work well on a particular farm. The specific selection depends on the climate and soils, the expertise of the farmer, whether there are livestock on the farm or nearby, equipment and labor availability, family quality-of-life considerations, and financial reality (potential price minus the cost of production). (However, vegetable farmers will sometimes include low-return crops in their rotations because customers expect to find them in the mix at a farm stand or farmers’ market.) From an ecological view, longer and more complex rotations are preferred over shorter ones. It also makes a lot of sense, once equipment is in place, to stay flexible instead of having a rotation set in stone. If you’re ready to adjust to rapid market changes, changes in labor availability, crop pest outbreaks, or unusual weather patterns, you’ll be in a stronger position economically, while still maintaining a complex rotation.
