Context:

Adopters of HT crops practice conservation tillage more than growers of conventional varieties.
Since the 1980s, the adoption of conservation tillage practices by U.S. farmers has been facilitated
by the availability of post-emergent herbicides that can be applied over a crop during the growing
season. Post-emergent herbicides are especially beneicial in no-till production systems because
these herbicides control weeds without tilling the soil. HT crops have helped spread no-till farming
further since they often allow a more effective system than just using other post-emergent herbicides
