Super Compost

Organic Compost & Soil Conditioners

Soil-like material rich in stabilized carbon

produced from the breakdown of organic

materials. Considered a "soil amendment"

rather than a fertilizer because it usually

contains smaller amounts of nitrogen,

phosphorus and potassium than

mineral-based commercial fertilizer products.


Benefits of applying compost include:

•restoring or enhancing the ability of sandy soil to hold

moisture and clay soils to drain;

•repairing or preventing damage caused by erosion; and

•aiding plant growth – e.g., in residential gardens, public landscapes or after construction and mining projects are completed.
