What does Chemigation refer to?

Chemigation refers specifically to the application of pesticides and fertilizers through irrigation systems. This method allows for the even distribution of these chemicals, taking advantage of the existing irrigation infrastructure to ensure that the application is efficient and effective. By utilizing water as a carrier for pesticides and fertilizers, chemigation can enhance the uptake of these substances by plants, leading to improved agricultural outcomes.

In contrast, the other choices provide definitions that do not align with the established meaning of chemigation. The removal of pesticides from the environment, for example, relates more to environmental management or cleanup efforts rather than the application process. Similarly, agricultural waste management and maintenance of pesticide equipment pertain to different aspects of agricultural practices that are not associated with the act of applying chemicals through irrigation systems.
