ABSTRACT:
Disclosed is a method for enhancing the concentration of vermicompost comprising the steps of liquefying and agitating a vermicompost feedstock; separating large bodies from the liquefied feedstock and further separating the remaining portion into first and second sub-portions; centrifugally separating the first sub-portion into light and heavy portions; returning the light portion to the liquefying and agitating step; separating biological vermicompost components from the second sub-portion and heavy portion using a biological filter; returning the liquid to the liquefying and agitating step; innoculating the biological vermicompost components with food and/or supplements; further enhancing the concentration of the biological vermicompost components by allowing the biological vermicompost components an effective amount of time to multiply and dry; and packaging the biological vermicompost components.
