<p>PROBLEM TO BE SOLVED: To provide a mineral enriched fertilizer which is free from environmental pollution, such as odors, in the composting process of organic waste, such as livestock waste, is alkaline, contains the minerals required by plants with good balance and has good quality. SOLUTION: This mineral enriched fertilizer is prepared by adding and mixing fossil seashells which are resulted from the embedment and deposition of various kinds of nekton, plankton, algae, seaweed, etc., consisting of calcareous materials, silicic acids, etc., and are the crystalline bodies having corrosive and soluble properties, to and with the organic waste, subjecting this mixture to adsorption of odors, etc., together with moisture control and subjecting the mixture to aerobic fermentation. As a result, the fertilizer which is free from the odors, etc., is weakly alkaline, contains the minerals with good balance and is adaptable to a recycling system of organic resources may be obtained. The fertilizer lends itself to the production structure of a resource circulating type and to the production of agricultural products keeping up with the standpoint of consumers, helping to provide the social structure of the next generation-oriented ideal area circulation type.</p> |
