What are the benefits of compost?

Soil / Plant Improvements

  • Improves soil structure
  • Improves nutrient holding capacity
  • Reduces soil compaction and crusting
  • Reduces fertilizer requirements
  • Increases ease of cultivation
  • Improves root growth and yields
  • Improves water infiltration and drought tolerance
  • Protects plants from disease
  • Increases microbial and earthworm populations
Pollution Prevention / Remediation
  • Prevents erosion of embankments, roadsides, and hillsides.
  • Binds heavy metals in contaminated soils.
  • Degrades many pesticides.
  • Absorbs odors and degrades volatile organic compounds.
  • Diverts organics from landfills into compost, reducing waste burden and methane production.
