Using Chemigation Safely and Effectively Graphic

Chemigation is the practice of applying agrichemicals to cropland using an irrigation system to distribute both the water and chemical.

Nebraska Chemigation Act                                  Nebraska Department of Environment and Energy logo

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

The Nebraska Department of Environment Energy developed and implemented the rules and regulations necessary for irrigators to utilize the practice. Under the NDEE rules, Nebraska's Natural Resources Districts were given the responsibility to manage the chemigation permit component that ensures that proper safety equipment is present and functioning properly.

Certification program

The chemigation certification program is responsible for training Nebraska producers about the Nebraska Chemigation Act and the Rules and Regulations as developed by the NDEE. Certification applicants are required to attend a training program and pass an exam. The Act allowed the NDEE to contract with the University of Nebraska to deliver the training program.

Chemigation Training Dates 2020  - On site training 

A chemigation applicator certification card will be issued to successful applicants by the NDEE. The certification expires on January 1, 4 years after it is issued. For example, certifications issued in 2011 will expire on January 1, 2015.

Online certification

The online certification is for recertification, the final test cannot be taken for initial or first time chemigators.  The materials needed to complete the training program online can be accessed from this page or by contacting your local UNL Extension Office for a printed copy of the materials.

Initial or first time chemigators - the online training program covers all of the information presented at the in-person training events and uses the same test. The training program is designed so that you can complete the training (but not the final test) in a series of online sessions if you wish. It consists of a series of modules which contain text, video clips and calculators to provide chemigators with the necessary information to employ chemigation in an effective, efficient and environmentally safe manner while safeguarding farm workers involved in chemigation. Please Note:  The on-line Chemigation Test (final) will need to be taken at a county extension office. 

Below are instructions on how to complete each module of the training program.

In order to complete your training, you need to study each chapter and complete any activity related to that module. Each module/activity is "locked" meaning you will not be able to proceed until completing the previous section.
