HARTINGTON — The Nebraska Chemigation Act was passed in 1987 to help ensure that the backflow of chemicals would not contaminate the ground and surface waters of the state from irrigation water application systems used to apply crop nutrients and pesticides (chemigation).

Certification is valid for four years, and training is provided through UNL Extension.
