How to Use
Consult rate tables printed on bag labels.
Verify product analysis and rate for plants in your production system (for assistance, contact your regional ICL Territory Manager or for testing call the ICL Lab at 877-467-8522).
Irrigation frequency and volume should be adjusted during the crop production cycle according to crop type, environmental conditions, and desired soluble salt levels.
A product trial is recommended before adopting a new fertilizer program or making full-scale changes to standard cultural practices (test several rates on representative plant types).
Store in a clean, cool, dry place.
