1
Verify product analysis, longevity, and rate for plants in your production system (for assistance, contact your regional ICL Territory Manager or call ICL Customer Service at 800-492-8255)
2
Consult rate tables printed on bag labels and product sheets
3
For incorporation, blend into growing media to ensure uniform distribution of fertilizer
4
Do not over-mix (doing so could damage fertilizer coating)
5
Growing media should be used within two to four weeks after incorporating fertilizer
6
For top-dress applications, spread fertilizer evenly on container surface (avoid piling fertilizer directly against plant stem)
7
Irrigate after application (irrigation frequency and volume should be adjusted during the crop production cycle according to crop type, environmental conditions, and desired soluble salt levels)
8
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)
9
Use caution when applying to plants being over-wintered under cover (if you can't monitor soluble salts and/or adjust irrigation practices, avoid Fall and Winter applications
10
Store in a clean, cool, dry place
