A fortifier for growth and flowering in horticulture, trees and ornamental plants, aromatic plants and fruit trees, from wastewater from brewer's yeast with a very low protein concentration. The method including the step of: filtered by 80 m; magnetic treatment of the liquid; addition of 0.1 to 20 g/l phosphate and 10 to 20 g/l glycose. Fermentation is carried out keeping the free amino acid content greater than 0.1%, the content of Mg.sup.+2 greater than 0.1%, total nitrogen, phosphate, and potassium below 3.0%, the content of protein from 0.5% to 1.0% and EDTA from 0.02% to 0.2%, all by dry matter weight; addition of microbes from the environment; at temperatures of 15 C. to 40 C. with gentle agitation, for 24 hours to 30 days; subsequent filtering and pH adjustment. It has been found to be effective in various crops.

A self-regulating compost bin is formed from a temperature-resistant plastic, and is configured to regulate its internal temperature and inform the user when harmful pathogens within the compost are eradicated. The main body of the compost bin is hollow with a lid having a window through which sunlight may enter to heat the compost. The compost bin may also have a controller in communication with a fan. The controller is configured to control an operation of the fan. The controller is also in communication with a transceiver. The controller alerts a user when the interior of the main body remains at a predetermined temperature for a predetermined length of time to ensure the compost is safe for use.

The present application provides a reactor with an inclined bottom gas-inlet for aerobic fermentation. A fermenter is provided with a circular inner tank, end covers and a jacket. An airtight fermentation space is formed in the fermenter by the inner tank, an upper end cover and a lower end cover. A feed opening and an exhaust outlet are arranged at an upper part of the fermenter, and a discharge opening is arranged at a lower part of the lower end cover of the fermenter. An energy-saving stirrer is mounted in the fermenter. A plurality of air chambers are arranged at an external wall at the bottom of the inner tank of the fermenter and are within the jacket. A plurality of aeration nozzles are defined on an inner side of each air chamber, and the aeration nozzles are disposed next to the inner tank.

A method of determining the volume of organic material in a composting device includes rotating a mixing paddle in a composting bin that stores the organic material; monitoring the torque from a motor that rotates the mixing paddle as the mixing paddle rotates; and determining the height of the organic material in the composting bin based on the motor torque and the angular displacement of the mixing paddle. The resulting height can be used to determine the volume of the organic material.

A composting chamber for commercial on-site (for example, grocery store) processing of organic matter comprises a simple chamber, with an intake for shredded matter and an auger for movement of matter in situ, said auger operating on a feedback loop based upon fill level of chamber.

A controller for a compost system comprises a plurality of control outputs in communication with a plurality of compost devices. The control outputs are configured to identify an error condition of at least one of the plurality of compost devices. The controller is configured to control a first compost device configured to control a first environmental condition and control a second compost device configured to control a second environmental condition of a compost chamber. The controller is further configured to deactivate the first compost device in response to an error condition during a compost cycle. The controller controls the second compost device in response to the first compost device being deactivated preserving the compost cycle by compensating for the error condition in the first compost device.
