Looking out over my fields today, it’s hard to imagine them as the rundown acres I originally purchased with my wife back in 1958.

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.

It's somewhat ironic that trying to farm right out of college during a period of bad flooding in northeastern Saskatchewan led me several years later to cropping systems research in a semi-arid area where I could really use some of that excess water! Along the way, I did graduate studies in forage genetics at the University of Guelph in Ontario and at the University of Minnesota.

Anyone who heard me talk about my operation at the 2006 National No-Tillage Conference in St. Louis knows that I'm as close to paranoid about soil loss as a person can get.

When I first gave no-till a serious look in 1972, we were lucky to harvest 60 bushels of corn per acre in southwestern Nebraska. I couldn’t have dreamed then that we would be setting ambitious but realistic yield goals of 250-bushel corn and near 100-bushel soybeans and wheat for 2006.

Our shift to no-tillage started after we attended a Top Farmer Crop Workshop at Purdue University in 1989. We were told about the big gains that some of the early no-till innovators were getting by seeding soybeans with a no-till drill rather than in 30-inch rows. It seemed like a good system to consider.

We started no-tilling almost by accident in the late 1970s in southern Idaho. One of our spring barley fields was set back by frost and didn’t grow very tall.
