Which is a common result of improper soil incorporation?

Improper soil incorporation of herbicides can lead to decreased herbicide effectiveness for several reasons. When herbicides are not adequately mixed into the soil, they may not reach the targeted weed roots or may be exposed to degradation from environmental factors such as sunlight and microbial activity. This inadequate incorporation limits the herbicide's ability to control weed populations effectively. As a result, the intended impact on weed management can be significantly reduced, leading to poor control and potentially requiring additional applications or alternative management practices.

Other possible outcomes, such as enhanced growth of weeds, environmental pollution, or faster breakdown of the herbicide, may occur as a consequence of poor incorporation practices but are not the primary consequence of this issue. The primary focus here is how improper incorporation directly hinders the herbicide’s performance in managing weeds effectively.
