Fertigation and Chemigation Injectors


Chemigation Systems International

A subsidiary of Chemindustrial Systems Inc., Chemigation Systems International has been building American-made fertilizer and chemical injectors for agriculture and turf for over 40 years.
  • For FERTIGATION:  fertilizer injectors
    Reliably apply fertilizer through an irrigation system. CSI offers very high fertilizer injection rates per dollar and extreme durability.
  • For CHEMIGATION:  chemical injectors
    Precision, long-lasting, high capacity chemical injection systems.
  • pH control
    Economically correct acidic or basic pH values in irrigation pipelines by using aggressive chemicals that would quickly kill ordinary metering pumps.
  • Proportional injectors
    In these models, the rate of injection changes in response to changes in the irrigation water flow rate.
  • Multi-stream injectors
    Control injection of up to four different fertilizers and/or chemicals into an irrigation system simultaneously or sequentially, in any combination. These systems minimize the moving parts in your system while maximizing flexibility and reliability.
