Penn Valley Liquid Humus is based on the Aeromaster Compost Tea extraction process which extracts the humus and valuable microbial and non-microbial contents from high quality humus compost and places it into a water suspension.
An activator and microbial food source is added to the extracted tea just prior to field application which stimulates the microbial population and starts rapid microbial reproduction in the field. With the extraction process, the rapid microbial reproduction takes place on the leaves of the plant and in the soil.
These natural environments allow all of the extracted microbe species to rapidly reproduce, supported by humus. When extracted compost tea is used, most growers are amazed by the actual results that they experience.
