CHEMIGATION
Chemigation is the process whereby agriculture chemicals, (pesticides and fertilizers) are applied to land or crops in or with water through a CLOSED irritation system. (The term "pesticides" includes herbicides and fungicides as well as insecticides.)

Chemigation DOES NOT include the process whereby chemicals are applied to land or crops in or with water pumped from a stock watering well, a domestic well with a diameter of two inches or less, or from a tail water collection pond.

A CLOSED IRRIGATION SYSTEM includes any device or combination of devices having a hose, pipe, or other conduit, which connects directly to any source of groundwater or surface water, through which water or a mixture of water and chemicals is drawn and applied for agricultural or horticultural purposes.

FERTIGATION
Fertigation has been described as the application of plant nutrients in irrigation water to accomplish fertilization.

Fertigation is becoming widely accepted in the industry due to the fact that a properly designed system will perform accurately, is now, economical, easy to install, saves time, labor and most importantly, will save you money. A proper system will eliminate waste, sludge and residues. It allows one to "fine tune" fertility levels, and will monitor the rates of fertilizer being applied.

To fertigate, you must use fertilizer. The type of fertilizer you select should be a high quality liquid containing low salts, high purity, complete solubility and an acceptable pH. The analysis of fertilizer should be directed toward your specific needs, based upon soil, medium and tissue analysis. The nutrient ratios, including secondary and minor elements are probably endless. However, the fertilizer selected must fit your program's requirements. Your system should allow you to fertilize with ease, increase and/or adjust growth, fine tune your color and monitor the health and the marketability of your production.
