Directions for use
  • Verify your product analysis, longevity and rate for your plants in your production system. For further guidance contact your local ICL-SF Territory Manager or call ICL-SF Customer Service @ 800-492-8255.
  • Rate tables are printed on bag labels and can be found on product information sheets as well as on www.icl-sf.com.
  • For incorporation, blend into growing media to ensure uniform distribution of fertilizer prills. Do not over-mix to avoid damaging fertilizer coating.  Growing media should be used within two to four weeks after incorporating fertilizer.
  • For top-dress applications, refer to suggested rate tables on bag labels and product sheets. Uniformly spread fertilizer on container surface; avoid piling fertilizer dose 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 cannot monitor soluble salts and/or adjust irrigation practices, avoid Fall and Winter application.
  • Product storage: Store in a clean, cool, dry place.  Re-seal opened bags by folding top down and securing.
