When the Christensen family moved to a new farming location in southwestern Wisconsin 5 years ago, they took a hard look at the many benefits of no-tilling.

For as little as 20 cents per acre, no-tillers can significantly increase the effectiveness of their post-emergent herbicide applications. The addition of inexpensive ammonium sulfate (AMS) to the tank mix can boost no-till weed control by as much as 41 percent in some cases, according to Bryan Young, a weed scientist at Southern Illinois University.
