What method involves placing herbicide beneath the soil surface with minimal disturbance?

The method that involves placing herbicide beneath the soil surface with minimal disturbance is soil injection. This technique allows for precise placement of the herbicide directly into the soil where it is needed, minimizing disruption to the surrounding environment and helping to prevent surface runoff.

Soil injection can be particularly effective for controlling weeds while reducing the risk of harming desirable plants or other organisms in the vicinity, as it limits exposure to the herbicide. Furthermore, by placing the herbicide below the surface, it can be more effective in targeting root systems of weeds, leading to better control and a longer-lasting effect compared to surface applications. This method leverages the ability of certain herbicides to be taken up through roots, allowing for thorough weed management with minimal collateral damage.
