We made our initial commitment to continuous no-tilling during the early years of Roundup Ready soybean development. We had gained experience with no-tilling double-cropped soybeans into wheat stubble, but we weren’t totally impressed. We found that heavy residue from the wheat crop tied up nitrogen and was costing us fertilizer dollars. We were also experimenting with no-tilling soybeans into corn stubble, which was getting easier with new narrow-row equipment.

It’s hard to remember when we didn’t do some type of no-tilling or reduced-tillage on our southeastern Illinois farm. We really got into high gear around the mid-1980s. Some of our first results were with corn planted into wheat stubble or a red clover cover crop. We took advantage of the PIK (Payment in Kind) federal farm program during those years to make a serious commitment to long-term no-tilling.

OUR farm in southwestern Iowa has been a leader in soil conservation since the “dirty” 1930s. My father was one of the first individuals to install field terraces on our highly erodible land to slow water runoff and save the topsoil. We’ve kept a copy of the Des Moines Sunday Register from October 1968 that describes how Dad (Edgar Wahling) and I constructed the first push-up grassed-backslope terrace in the United States.

The first time i heard about no-tilling was at Kansas State University in 1973. We talked about studies being done in Virginia, Ohio, Kentucky, Missouri and other places where no-till first took hold. I came home from those discussions and thought about putting no-till to work on our farm, but we faced a tough challenge. Based on KSU’s no-till handbook, our clay soils (shallow topsoil, super-tight subsoil) are classified as “needing special management” for no-till.

No-tillers could gain income for their crop residue as the United States seeks energy independence and relief from soaring oil prices.
