NOVELTY - A manure is prepared by processing substance such as wastes of livestock, residue of animals and plants by adding aerobic and anaerobic microorganisms and intermittently supplying air. The mixture is stirred during supply of air.    USE - For manufacturing manure suitable for growth of agricultural products by fermenting livestock waste and residue of animals and plants.    ADVANTAGE - The method enables to produce manure by fermenting waste products of livestock and residue of human and animals. The manure is suitable for growth of agricultural products and modify soil contaminated with agrochemicals. The microorganisms floating in the atmosphere is effectively utilized for accelerating fermentation. The proliferation of aerobic bacteria is accelerated without generating any bad smell. The growth of anaerobic microorganism in the mixture is accelerated intermittently by reducing the oxygen concentration of the supplied air. The resistance of aerobic bacteria is improved. The aerobic bacteria effectively deodorizes the bad smell generated by fermentation. The remaining number of survival of anaerobic and aerobic bacteria are adjusted easily by intermittently supplying air, thereby large quantity of fertilizer with high quality is obtained. The mixture is continuously stirred, thereby sets almost completely with uniform fermentation conditions. The fermentation is accelerated effectively by proliferation of useful microorganism and harmful microorganisms are killed by maintaining the temperature of mixture at 60 degrees C or more. The magnetizing water containing minerals and various microorganisms, accelerated the proliferation of bacteria.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for fermentation type forming manure system which comprises a fermentation tank, in which the livestock waste and residue of animal and plant and aerobic and anaerobic microorganism are mixed, an injection unit, an outlet for removing the fermented mixture from the fermentation tank and an air supply apparatus which returns the gas to the mixture intermittently. The apparatus is equipped with a stirrer for stirring the mixture supplied with air.    DESCRIPTION OF DRAWING(S) - The figure shows manufacturing process of fertilizer by fermentation.
