Abstract: Method of producing compost tea is disclosed the steps of: Introducing a flow of aqueous solution over and through a basket. This flow is used to leach and wash microorganisms and nutrients from organic compost and other organisms and nutrient-rich materials from the basket into the culture tank. The culture tank collects and cultures microorganisms and nutrients, creating compost tea. Compressed air is used to power this circulation instead of mechanical pumps which injure the organisms as they pass through.
