When the owners of Cronin Farms near Gettysburg, S.D., compared input costs to net profits in 1989, it was clear there was room for improvement in their farming process. Together with their farm manager of 41 years, Dan Forgey, and the rest of the farm’s employees, they began investigating the benefits of no-till.

When people ask me for a quick answer to justify shifting to no-tillage, the best one I can come up with is this: Yield is not measured in bushels or tons per acre. Yield is measured in net dollars per acre. No-tilling equals more dollars in the bank.
