Compost is...    

Compost is the organic-rich, thermally-treated, biologically-stable, degradation product of an aerobic degradation process. *

However, there are as many types of compost as there are feedstocks and different uses.  Compost may possess a wide variety of parameters such as carbon to nitrogen ratio, microbial diversity, moisture content, grain size, stability, and nutrient content. These parameters are determined by both process and feedstock composition and can be controlled to produce a product to fit a particular purpose.  Compost may also be the aerobically treated residual of an anaerobic digestion process.  This material is a specific sub-category of the typical aerobically digested organic residual, which also strongly depends upon feedstock and process for its characteristics.

A compost prepared for use as a mulch will require a higher C:N ratio and larger particle size than one intended for a vegetable garden amendment.  A roadside stabilization compost will require a larger particle size than one intended to top dress a golf course turf.  The use of compost adds organic matter and nutrients, increases the water holding capacity, and increases the microbial diversity of soil systems where human activities such as logging, plowing, or pollution, may have sterilized the ecosystem.



Terre-SourceLLC can help you with the many uses and benefits of compost:  

             Compost can be used to restore denuded industrial sites and provide a growth media for revegetation of such sites    
             Compost can be used to immobilize certain inorganic contaminants in soils both chemically and physically by providing growth media for vegetation    
             Compost can be used to prevent erosion by intercepting water and slowing its impact on bare soils as well as improving infiltration at the expense of overland flow    
             Compost can be used to reduce plant pathogen presence and impact on certain crops    
             Compost can be used to provide slow-release nutrients to crops reducing reliance upon synthetic and potentially leaching fertilizers    
             Compost provides a carbon sink over incineration and promotes carbon sequestration in plant material by promoting plant growth thus reducing greenhouse gas emission
