Soil ReGen Benefits

  • Improves soil structure and aggregation.
  • Helps reduce soil compaction.
  • Aerates soil and improves oxygen availability in soil.
  • Increases infiltration and permeability.
  • Increases water and nutrient holding capacity.
  • Contains all essential elements required for photosynthesis.
  • High Cation Exchange allows plants to more effectively utilize nutrients, while reducing loss by leaching.
  • Aids the colonization of beneficial soil
    microorganisms which supplies humic acid and encourages vigorous root growth.
  • Provides carbohydrates such as alginic acid and mannitol.
  • Contains mycorrhizae for improved nutrient and water uptake, and increased plant stress tolerance.
  • Provides stabilized organic matter (Humus).
Soil ReGen KEY Ingredients

Aerobic Compost from Suståne:
Biologically stable, microbially diverse, rich in plant nutrients, humic substances, and high-quality organic matter. Aerobic compost is the foundation for improving soils. USDA Biobased.

BioChar is made from biomass via pyrolysis and is a stable, carbon-rich material that acts as a scaffold to retain nutrients, bind organic by-products, and support microbial growth for improved nutrient cycling. 

Humates are a naturally-occurring, carbon residues that can enhance root uptake of nutrients and further stimulate soil life.

Mycorrhizal Inoculant:
Mycorrhizae are mutualistic fungi that enhance plant growth and health by improving nutrient and water uptake and protecting against root pathogens. They also improve soil structure for better soil health and plant establishment.
Suståne supplies a specifically selected suite of four endo mycorrhizae species.

Pumice is highly a porous mineral and holds both water and air— critical to well-conditioned, aerated soils. With a naturally lightweight structure, it provides an excellent platform for supporting the root systems of diverse plants on green roofs and other urban settings.

Zeolite has a large surface area and the molecular structure and porosity provide the ability to retain moisture and nutrients in a manner complementary to pumice
