Collection: Fertilize Through Your Irrigation System
What is Fertigation?
Fertilizing through an irrigation system is referred to as "fertigation." Foliar fertilizers can be applied through irrigation lines, but you must increase the foliar rates by at least five times. If the fertilizer is water soluble and can be used as a foliar fertilizer, you can also use it for fertigation. Check out our Fertilizer Solutions Chart for more information. Some dry micronized fertilizers are injectable, but please note which of these products must be premixed with water before being injected. Irrigation lines should always be cleaned after fertigation by flushing with clean water before and/or after fertilizing. Use Therm X70 when flushing irrigation lines.
