Conventional measures (grams) 5 16 71 94 141 283 How to Use 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) Consult rate tables printed on bag labels and product sheets For incorporation, blend into growing media to ensure uniform distribution of fertilizer Do not over-mix (doing so could damage fertilizer coating) Growing media should be used within two to four weeks after incorporating fertilizer For top-dress applications, spread fertilizer evenly on container surface (avoid piling fertilizer directly against plant stem) 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) 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) 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) Store in a clean, cool, dry place
