METHOD FOR PRODUCING LIQUID FERTILIZER ON BASIS OF LIQUID FERTILIZER QUALITY CERTIFICATION (LFQC) OF LIVESTOCK MANURE, HIGH-QUALITY LIQUID FERTILIZER PRODUCED THEREBY, AND METHOD FOR PRODUCING CHLORELLA MICROBIAL FERTILIZER
METHOD FOR PRODUCING LIQUID FERTILIZER ON BASIS OF LIQUID FERTILIZER QUALITY CERTIFICATION (LFQC) OF LIVESTOCK MANURE, HIGH-QUALITY LIQUID FERTILIZER PRODUCED THEREBY, AND METHOD FOR PRODUCING CHLORELLA MICROBIAL FERTILIZER
The present invention relates to a method for producing liquid fertilizer on the basis of the liquid fertilizer quality certification (LFQC) of livestock manure, high-quality liquid fertilizer produced thereby, and a method for producing chlorella microbial fertilizer by using the high-quality liquid fertilizer. The present invention is characterized in that discharged liquid fertilizer of livestock manure is treated with high temperature aerobic liquid fermentation; the liquid treated with high temperature aerobic liquid fermentation is after-fermented to produce fermented liquid fertilizer that meets the criteria for the LFQC of livestock manure; the produced fermented liquid fertilizer is treated with a separator to produce high-quality liquid fertilizer with reduced solid particles; ammonia gas generated during the high temperature aerobic liquid fermentation treatment is brought into contact with phosphoric acid-administered water in an ammonia collection tank to collect ammonia; and the high-quality liquid fertilizer and the ammonia-collected solution are properly mixed so as to be used as a fermentation medium for culturing chlorella in replacement of an expensive BG11 medium. Therefore, the present invention can produce high-quality liquid fertilizer that meets the criteria for the LFQC of livestock manure, and utilize the liquid fertilizer to produce chlorella microbial fertilizer, thereby providing the effect of reducing the production costs of agricultural products.
