There is a strong connection between chemigation, fertigation and irrigation, the goal being for each plant to receive a uniform quantity of water and additive. Uniformity of application is indeed the essential factor in successful fertigation and chemigation.
Uniformity depends on several factors such as the homogeneity of water application, adjustment and use of injection equipment, compatibility between additives and application conditions, especially where wind conditions are concerned.
Pivots and linear move systems are the best sprinkler application systems, given their high potential uniformity of water distribution over large areas. Small amounts can be applied, even during rainy periods or at night under windy conditions.
Chemigation is the application of an approved chemical (fertilizer, herbicide, insecticide, fungicide or nematicide) with the irrigation water applied by the center pivot.
