  • Highly complex assemblage of:
    • geological materials,
    • dead organic matter,
    • living roots,

Only about 1% of the microorganisms found in soil have been identified so far
95% of food production relies on the soil
Soils store more carbon than the atmosphere, and all of the world’s plants and forests combined.
Earthworms are a real hero of healthy soils – Earthworms do amazing work in soils! Their activity offers many benefits, from increased nutrient availability and better drainage, to creating a more stable soil structure.
