Increases moisture infiltration and permeability of heavy soils -- improving   drainage and reducing erosion runoff

      Improves moisture holding capacity of light soils-- reducing water loss and nutrient leaching

      Improves and stablizes soil pH

      Improves cation rxchange capacity (CEC) of soils -- improving their ability to hold nutrients for plant use

      Supplies a variety of macro and micro nutrients

      Supplies significant quantities of organic matter

      Supplies benfical micro-organisms to the soil -- improving nutrient uptake and suppressing certain soil-borne diseases
