Chemigation: The practice of applying agrichemicals to cropland through an irrigation system.

Nebraska Chemigation Act
The goal of the Nebraska Chemigation Act is to protect the groundwater and surface waters of Nebraska from contamination by fertilizers and pesticides. To accomplish this goal, the Act establishes legal requirements for the use of chemigation as a method of nutrient or pesticide application.

The Nebraska Department of Environment and Energy administers the rules and regulations that chemigators must follow to utilize the practice. Under NDEE rules, Nebraska’s Natural Resources Districts (NRDs) are responsible for issuing permits for chemical injection locations, which ensures that necessary safety equipment is present and functioning correctly.
