Abstract: Multiple Tray Vermicomposter with Thermal Siphon Airflow is a vermiculture composting device that uses earthworms to create compost where worms eat and digest food to excrete compost. It is a multiple tray system with a base and a lid. New compost trays with freshly loaded food and bedding are stacked on top of older trays containing worms and compost to instigate a continuous upward migration of the worms thereby creating continuous compost production. Compost trays have permeable bottoms to allow worms to pass through. Compost production is accelerated from thermal siphon airflow to provide ample airflow to the worms without the requirement of a power source. Light-tight air-permeable connections between trays, lid, and base, also accelerate compost production by keeping the worms completely dark. If worms fall through the bottom compost tray, there exists a ramp to enable the fallen worms to climb back into the bottom compost tray.

Abstract: The device and method invented provides a unique means to extract and multiply, by the millions, beneficial aerobic microbes found in compost and vermicompost to be applied to soil and plants in liquid form. Compared to many compost tea making devices being sold, the invented device is truly simple and can be dismantled and cleaned in under twenty minutes. Most of the parts are not glued and can be pulled apart. The device and method uses air pumps alone to actually circulate the water and can be used with or without a mesh extractor. This is achieved by the insertion of an air diffuser into the piping used, which infuses the water with oxygen while circulating the water, into either, an extractor containing compost or a body of water containing compost. Concurrently additional diffusers infuse the body of water with oxygen.
