“Only three things can bring soils back to their natural organic matter level: permanent forestland, permanent pasture or continuous no-tilling...” — Carlos Crovetto, Conception, Chile
CHALLENGE THE EXPERTS. Conference speakers often tackle even more specific questions from attendees after scheduled presentations.
Dan Towery called on growers to shoot for higher profitability by transitioning to continuous no-till. The former staffer at the Conservation Tillage Information Center estimated only 10-15% of U.S. cropland has been continuously no-tilled for over 5 years.
Towery says any yield drag with continuous no-till is due to poor management decisions during the transition.
Jim Kinsella, a widely known no-tiller, advocated the use of strip-tilling to take full advantage of the warm, dry seedbed of conventional tilling while also reaping the environmental benefits of no-tilling.
The Lexington, Ill., grower suggests fall strip-tilling ahead of corn provides low-cost insurance against the slow growth in a cold and wet spring.
