Even as no-till was growing during the 1980s, Randy Caviness wasn’t completely convinced about the practice. He worried about weed control, and he hadn’t seen many examples of no-tilled crops working very well in his area.

Caviness hasn’t looked back since. His farm has been 100% no-till since the mid-1980s. Since yields are reaching or exceeding county averages, he plans to keep it that way.

We would get something like a 2-inch rain, the waterways would form in the fields and we would be losing soil.”
Back in the mid-1970s, Buffalo planters were emerging that could plant into sod where conventional planters could not.
