Suståne Concentrated Compost provides the benefits of nutrient-rich compost in a concentrated dry form. Suståne Concentrated Compost is easy to apply and replenishes the soil with a rich supply of stabilized organic matter and essential nutrients required for quality growth. Suståne Concentrated Compost provides a combination of plant nutrients and organic substances derived from biologically stable aerobic compost.

Recommended Use:

For use as a general soil builder, erosion control, reclamation, bio-remediation, revegetation, and building or disturbed or depleted soils. Native establishment and soil reclamation and remediation and in the production of certified organic crops.

Benefits of Suståne Concentrated Compost

  • Provides the benefits of compost in a dry, concentrated form which minimizes transportation and application costs.
  • Contains all primary, secondary and tertiary nutrients for plant growth eliminating the need to apply additional fertilizer.
  • Adds approximately 10% humates by weight.
  • Low Salt Index (6) requires no delay in planting following application.
  • Supplies soil with 60% Organic Matter in the form of stabilized humus.
  • Carbon: Nitrogen Ratio (9:1) ensures no N immobilization in soil.
  • Increases the nutrient and water holding capacity of the soil.
  • Enhances the soil’s ability to suppress plant pathogens.
  • Improves and sustains soil health.
  • Improves buffering against changes in soil pH.
  • Increases the soil’s C.E.C (cation exchange capacity).
  • Improves soil structure, porosity, and stability leading to greater root development, infiltration, and soil micropores.

Always Safe for Plants, People, and the Environment

  • Manufactured by Suståne in the USA at an EPA-permitted facility.
  • Pathogen and weed/seed-free, no blood, bone, or meat products.
  • The only organic allowed for export to over 50 countries worldwide.
  • USDA NOP, COR, EU, and JAS organic compliant.
  • Aerobic composting eliminates animal and rodent attraction to the application site.
  • Suståne will not attract flies or other insects. 
  • Suståne is fully composted - not sterilized; enhancing the soil environment for beneficial microbial populations.
