Description:
Suståne 8-2-4 natural and organic fertilizer which provides a balanced feed that promotes a rapid and vigorous vegetative establishment with 6 - 12 weeks of nitrogen in the organic slow-release form. Suståne replenishes the soil with a rich supply of humus (stabilized organic matter) and all of the primary, secondary and minor nutrients essential for quality growth. Suståne 8-2-4 provides a combination of dense plant nutrients and organic substances derived from biologically stable compost plus natural sulfate of potash and feather meal.
Suståne 8-2-4 provides a safe, simple, and cost-effective feeding solution for all types of crops. 8-2-4 provides balanced nutrition from seed through harvest. Suståne 8-2-4 is the perfect fertilizer for when you need significant quantities of organic slow-release nitrogen with low burn potential. Great for specialty crop production in high-quality soils or potting mixes.
Suståne 8-2-4 is a complete package fertilizer containing Slow Release Nitrogen, chelated micronutrients, organic phosphorous, and humic substances. Suståne 8-2-4 has been demonstrated time and again to surpass synthetic turf starter fertilizers and other sources of humates and plant biostimulants.
Recommended Use:
For use in the production of certified organic gardens, turfgrass and landscape maintenance, greenhouse bedding plants and annual establishment, erosion control, native reestablishment, and soil reclamation and remediation.

Suståne Integrated Soil Management Program:
Turf Establishment, Seeding, New Lawn Construction, Laying Sod and Sprigging:
Suståne 8-2-4 is a complete package fertilizer containing Slow Release Nitrogen, chelated micronutrients, organic phosphorous and humic substances. Suståne 8-2-4 has been demonstrated time and again to surpass synthetic turf starter fertilizers and other sources of humates and plant biostimulants.
Preplant - Broadcast and Incorporate into the top 4 in. (10 cm) of soil
- 25 lb. per 1,000 ft2 or 2,200 lb. per acre
- 12.5 kg per 100 m2 or 1,250 kg per hectare
Postplant (45-60 days) - Broadcast and water in
- 12.5 lb. per 1,000 ft2 or 1,100 lb. per acre

Turfgrass & Landscape Maintenance:
Professional landscapers have increasingly turned to Suståne 8-2-4 for use on high maintenance turf and landscaped environments. While synthetic fertilizers supply plant growth nutrients, they do not supply the organic matter required to maintain quality growth. Using fully composted natural fertilizers increases the levels of beneficial microbial activity, which in turn converts nutrients into plant-available forms.

- These rates are intended as guidelines. Suståne encourages a trial prior to changing any fertilizer program.
- Do not steam sterilize container mix after fertilizer has been incorporated.
- Do not store container mix more than two weeks after incorporating fertilizer. Plant material can be damaged by salt accumulation.
- Monitor electrical conductivity (EC) of container substrate throughout the production cycle.
- If the mix is stored longer than two weeks, leaching container mix may be required to remove accumulated salts.
- Adjust application rate as needed.
