Weed population dynamics in ridge-tilled soybeans with and without herbicides

Abstract

<p>Iowans are growing increasingly concerned about potential water pollution in Iowa due to heavy fertilization and extensive use of herbicides. The long-term productivity of soils has also come under scrutiny as the cumulative effects of erosion become more apparent. As a result, researchers are emphasizing the importance of developing new farming practices. One such practice already in use is ridge tillage.</p>
