Success with no-tillage — a radical change in farming from conventional methods — came thanks to the vision, courage and dogged determination shared by many — and from every corner imaginable.

Ingenuity and an “against the grain” perseverance are omnipresent in the “no-till story.” From the testing and perfecting of new chemical formulations … to the researchers and extension agents who ignored their bosses and tirelessly studied the practice … to the salesmen who quelled their doubts upon hearing one “no” after another … to those who created the forums, associations, workshops and field days.

But most important are the farmers themselves, who constructed their own farm-shop innovations, subjected themselves to ridicule for their “ugly, lazy ways of farming,” faithfully stuck with an unproven practice and worked the problems out. Farmers’ willingness to share successes and failures were priceless in transferring know-how to the next curious farmer. Competition, ego and embarrassment were set aside for the greater good.

  • Blacksmith John Deere fashions a broken steel saw blade to a highly-polished moldboard from which sticky prairie soils easily slide off while turning under the furrow. He and Leonard Andrus start manufacturing steel plows in Grand Detour, Ill., before separating into different plow companies 10 years later.

“Imagine how different things would have been for agriculture had John Deere been a chemist instead of a blacksmith? And instead of inventing a self-scouring steel plow, he’d invented Roundup …” — Randall Reeder, Retired Extension Agricultural Engineer, Ohio State Univ.

The $39,000 “soybean suit” that Ford proudly donned in 1941 was only one-quarter soy fiber, though (the rest was wool). Soy fabrics proved impractical, and most of the other non-food soy uses envisioned by Ford and others in the 1930s and 1940s never panned out.

  • Plowman’s Folly, authored by Edward H. Faulkner (an ag agent in Ohio), is released. “No one has ever advanced a scientific reason for plowing,” the book asserts. “The hottest farming argument since the tractor first challenged the horse was started by Faulkner's attack on the moldboard plow,” reports Time Magazine in its coverage of Faulkner vs. Walter T. Jack debate, an Iowa farmer, plow proponent and author of The Furrow and Us. Faulkner’s idea that seeds can be planted directly into residues from the previous crop motivates a soil conservation movement in the U.S. that would eventually take the form of no-till.

  • The No-Till Tillage Practices Survey (released in 1969) reports that Ky. led all states in 1967 with 150,000 no-till acres. That figure is 4 times as large as the next nearest states of Tenn. (35,000 acres) and N.C. (30,000 acres). 

“I was determined that we didn’t need to plow and could do things in one pass. We tried the Western lister in the late 1950s and ’60s, before the coulter came along. In those early days, I was just trying to buy the parts we needed. We went to the John Deere factory, and they snubbed us, but International Harvester and Ralph Baumheckel of IH’s Product Planning Group opened the doors for us. Ralph let me roam around the IH planter factory and pick out whatever we wanted. I’d say it was a breakthrough because Ralph followed up on what we were doing. He believed the discontinued IH Poyner Till Planter was a real innovation and that no-till concept would work.” – Early Ohio no-tiller Bill Richards.

  • At the request of Monsanto's Dr. Phil Hamm who was excited about two compounds studied in water softeners, recently transferred chemist John E. Franz studies herbicidal use and discovers the weed-killing properties of glyphosate, an application that had not been recognized by Stauffer Chemicals a decade earlier when it was patented as a metal chelator. The third compound Franz synthesized (glyphosate) would become the active ingredient in the original Roundup formulation that would change the face of farming.

"I tell farmers they can save soil, toil and oil," says Richard Foell, who promotes herbicides for the Ortho Agricultural Chemical Division of the Chevron Corp. "We’re looking for a 15-25% annual growth rate in no-till acreage. It has an excellent hold in the Northeast. It’s growing the fastest in the Southeast. Ohio, Indiana, Illinois and Michigan are coming along. But in the farm belt west of there, farmers are scraping, ripping, tearing and raping the bosom of Mother Earth."

  • No-till receives high-level support from Mo. farmer Peter Myers, who serves as Soil Conservation Service chief in President Reagan’s Administration (1982-1989).
