What does soil incorporation involve?

Soil incorporation refers to the process of integrating a pesticide into the soil, enhancing its effectiveness by ensuring that the chemical interacts with the soil and the pests it aims to control. This is typically achieved through mechanical means, like tillage, or by utilizing irrigation to move the pesticide deeper into the soil profile. By incorporating the pesticide into the soil, it can reach the targeted pest population more effectively and minimize the potential for drift or degradation on the surface.

Incorporation is crucial for specific types of pesticides that require soil application for maximum efficacy. It ensures uniform distribution and reduces the likelihood of exposure to non-target organisms or surface runoff. The other options describe different practices unrelated to the core concept of soil incorporation, such as harvesting or applying pesticides only on the surface, which do not achieve the intended depth of placement for effective pest management.
