What is soil injection?

Soil injection refers to the placement of a pesticide below the surface of the soil. This method involves using specialized equipment to deliver the pesticide deep into the soil profile, allowing for effective targeting of soil-dwelling pests and reducing the risk of surface runoff. By placing the pesticide underground, the active ingredients can more effectively reach their intended targets, such as plant roots and soil organisms that might be harmful to crops or plants.

This approach is valuable because it can minimize exposure to non-target organisms, including beneficial insects and the surrounding environment. Additionally, by injecting the pesticide directly into the soil, it often requires less quantity compared to surface applications, leading to reduced chemical use and potential environmental impact.

In contrast, the other methods provided in the question involve different forms of application or input that do not effectively describe the soil injection technique. For instance, applying pesticides at the soil's surface or along plant rows lacks the targeted depth and precision that soil injection provides. Similarly, adding fertilizers into the soil pertains to nutrient management rather than pest control.
