Concentrated Compost for Amending & Rebuilding Depleted Soils*

Suståne Concentrated Compost is intended as a general soil builder for broadcast application and improving soil organic matter levels, cation exchange capacity and enhancing and diversifying soil biological activity levels as shown in the microbial diversity index analysis. Final fertilizer recommendations should be based on laboratory soil tests and a crop's nutritional needs. 

Soil Preparation for Gardens, Landscapes and Agricultural Crops
  • Light, High Sandy Soil: 14 lb. per 100 ft2 of bed (70 kg per 100 m2)
  • Medium, Clay Loam Soil 10 lb. per 100 ft2 of bed (50 kg per 100 m2)
  • Heavy, Silty, Clay Loam 7 lb. per 100 ft2 of bed (35 kg per 100 m2)

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%).

 Broadcast Application

Incorporate into the top 2 - 4 in. (5-10 cm) of soil
Low Rate: apply 1,200 lb. per acre
Medium Rate: apply 2,000 lb. per acre
High Rate: apply 2,800 lb. per acre


For bio-remediation, forest re-establishment and extreme situations where topsoil has been removed or badly damanged, incorporate 136 lb. per 1,000 ft2 (65 kg per 100 m2) into the damaged soil.

Re-apply 60 to 90 days later at  a rate of 68 lb. per 1,000 ft2 (33 kg per 100 m2)

 *NOTE: Adjust fertilizer program for local conditions and requirements.
