Fertigation is the application of fertilizers, soil amendments, or other water soluble products through an irrigation system. Chemigation, a related and sometimes interchangeable term, is the application of chemicals through an irrigation system. Chemigation is considered to be a more restrictive and controlled process due to the potential nature of the products being delivered (pesticides, herbicides, fungicides, etc.) to cause harm to humans, animals or the environment. Therefore chemigation is generally more regulated than fertigation.
