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 crops, landscape, greenhouse soil mixes, and bedding plants for establishment.

Incorporating into Potting Soil Mixes and other Container Substrates:
Sustane 8-2-4 provides a constant release of nutrients when used with container substrates with an average temperature of 70oF / 21oC. When determining application rates consider all cultural practices including irrigation, container substrate physical characteristics, and growing environment.
Container Mix Application Rates:
| Container Mix Rates by Volume | |||||
|---|---|---|---|---|---|
| lb. per cubic yard | kg per cubic meter | ||||
| Low | Med | High | Low | Med | High |
| 5.5 | 10 | 15 | 3.3 | 5.9 | 8.9 |
Low Rate: Recommended for use on salt-sensitive species; when concurrent with liquid feed; with production systems utilizing low leaching fractions (less than 10%); and when applied to heavy potting substrates (total porosity less than 65%).
Medium Rate: Recommended for use on medium feeding species; on most nursery stock and foliage plants; and when liquid feed is not performed concurrently.
High Rate: Recommended for use on heavy feeding species; with production systems utilizing high leaching fractions (greater than 20%); and when applied to light, porous substrates (total porosity greater than 80%).

- 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.
