Calculating Chemigation Injection Rates
Chemigation is the application of agricultural chemicals (e.g., fertilizers, pesticides, and soil conditioners or amendments) into or through an irrigation system with the applied irrigation water. It is an efficient and cost-effective method of applying chemicals.
This fact sheet describes how to calculate injection rates for chemigation.
