Since we recently wrapped up our 22nd National No-Tillage Conference in mid-January, it’s a good time to reflect on a few items — both serious and not so serious — that have occurred at this annual event over the years.

John Baker maintains the consequences of plowing today are serious enough that tillage tools should come with warning labels that are similar to cigarettes.

In recent years, we’re produced a number of No-Till Farmer articles on the benefits of utilizing gypsum to improve plant nutrition and soil structure. Now, new research from Ohio State University indicates gypsum may play a key role in controlling the harmful algal blooms that are a growing concern in Lake Erie, the Chesapeake Bay, the Mississippi River and the Gulf of Mexico.

From 1991 until 1996, our publishing company produced a newsletter called Ridge-Till Hotline that was similar to what we were doing with No-Till Farmer. While the response to this paid newsletter was favorable, by the mid 1990s we didn't feel the ridge-till acres were going to continue to grow. So we halted publication, much to the regret of many die-hard ridge-tillers.

There’s no doubt that much of the rapid increase in no-tilled acres over the past 20 years is due to the extensive use of glyphosate-resistant corn and soybeans. Yet, extensive reliance on this single herbicide mode of action may be holding back the future growth of no-till. Even more worrisome is the impact it could have on simply maintaining the no-till acres we already have.
