Movement Of Triazine Herbicides In Conventional, Reduced Tillage, And No-Tillage Corn Production, William W. Witt, K. W. Sander
Soil Science News and Views
Herbicides are applied to over 90 percent of the corn acreage in Kentucky and triazine herbicides are used the most. Conservation tillage methods are often used to prevent soil erosion and to conserve soil water. However, as tillage is decreased the dependence on herbicides for weed control often increases. Minimizing herbicide movement from the application sites to non-target areas, such as ground and surface waters, is necessary to maintain optimum water quality.

Production Of No-Tillage Burley Tobacco, Jack M. Zeleznik, R. E. Phillips
Soil Science News and Views
In the early 1970's, researchers at the University of Kentucky produced burley tobacco by using no-tillage methods. These studies were abandoned a few years later due to poor growth, poor plant survival, and the lack of adequate weed control as the contributing factors. In 1984, the experimental production of no-tillage burley tobacco was reinitiated with the hopes that the newer herbicides would perform more effectively for no-tillage tobacco production. Burley producers could realize several potential advantages to no-tillage tobacco production if the yields produced by no-tillage were equal to or near those of conventional tillage. These potential advantages would include: …
