Improves soil structure and porosity - creating a better plant root environment

Increases moisture infiltration and permeability, and reduces the bulk density of heavy soils - improving moisture infiltration rates and reducing erosion and runoff

Improves the moisture holding capacity of light soils - reducing water loss and nutrient leaching, and improving moisture retention

Improves cation exchange capacity (CEC) of soils

Supplies organic matter

Aids proliferation of soil microbes

Supplies beneficial microorganisms to soils and growing media

Encourages vigorous root growth

Allows plants to more effectively utilize nutrients, while reducing nutrient loss by leaching

Enables soils to retain nutrients longer

Contains humus which helps in soil aggregation and makes nutrients more available for plant uptake

Buffers soil PH

Supplies macro and micro nutrients

May suppress soil borne disease

Can bind and degrade certain pollutants
