Soil performs vital functions in our ecosystems.
The soil stores reserves of water for plants, controls water seepage into streams and groundwater and reduces rapid runoff that could cause erosion and floods.
The soil stores carbon, (storing about four times more than plants), so it helps minimise the release of carbon dioxide into the air.
Soil microbes absorb nitrogen from the air and make it available as plant food. Nutrients are released as underlying rock fragments decay. Soil filters water and helps absorb and break down toxins.
So how does the application of compost help?
