ince the 1980s, Yuma, Colorado–based Agri-Inject has been advancing the use of mobile irrigation systems to apply fertilizer and chemicals in liquid form. This method of application, known as chemigation or fertigation, allows for the quick, low-volume, and continuous application of fertilizers and chemicals, thus spoon-feeding crops no more than they can absorb and preventing leaching and nitrate pollution. In this interview, Agri‑Inject CEO Erik Tribelhorn tells Irrigation Leader about the company’s role in developing chemigation from its beginnings and what the company is doing today.
Erik Tribelhorn: We manufacture chemigation and fertigation equipment that is designed to inject any liquid fertilizer, chemical, or water treatment product into irrigation pipelines. Fertigation refers to the injection of fertilizers, and chemigation

refers to the injection of chemicals. That makes up 90 percent or more of our business. The systems we manufacture are available in a range of sizes and configurations that is unrivaled in the industry, featuring pump sizes from less than 1 to over 300 gallons per hour; tank sizes from 10 to 600 gallons; a wide range of voltage options, material compatibility options, and plumbing configuration options; and more. We want to make sure that any fluid injection application in the world can be successfully accommodated using our equipment and engineering expertise. In many industries, including agriculture, golf, and sports parks, our customers are using their irrigation systems to deliver fertilizers, chemicals, or pest-control products through their water in a way that is palatable to plants, sustainable for the environment, safe, and usually less costly than alternatives. We’ve been involved in those markets all around the United States and in a significant part of the developed irrigated world.
