  • Method of producing compost tea and apparatus therefor
    Patent number: 6767381
    Abstract: Method of producing compost tea by passing an aqueous solution over and through a basket containing compost. This flow leaches and washes microorganisms and nutrients from 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 provide circulation instead of mechanical pumps, which can injure the organisms as they pass through.
