NOVELTY - A fertilizer production method involves pulverizing butchery blood of livestock, and transferring pulverized product into a fermentation tank, followed by stirring. Sodium hydroxide is added to water, and the obtained mixture is added to the fermentation tank, followed by adding proteolytic enzyme bromelain, nitrogen, phosphorus and potassium and agitating mixture. The agitated mixture is fermented, filtered and transferred to a storage tank. Chlorine dioxide is added to the storage tank, followed by fermenting mixture, filtering, cooling and packing to obtain finished product.    USE - Method for producing fertilizer.    ADVANTAGE - The method enables producing fertilizer with high amino acid content and quality in an economical and eco-friendly manner. The fertilizer promotes plant growth and flowering of plants.    DETAILED DESCRIPTION - A fertilizer production method involves supplying butchery blood (1000 L) of livestock into a pulverizing device, pulverizing and transferring pulverized product into a fermentation tank, where the temperature of the fermentation tank is maintained at 50 degrees C. The resultant product is stirred at a temperature of 30 degrees C. The fermentation tank is surrounded by a hot water jacket. Sodium hydroxide (50 g) is added to water (1 L), and the obtained mixture is added to the fermentation tank, followed by adding proteolytic enzyme bromelain, nitrogen, phosphorus and potassium and agitating at 40 degrees C. The agitated mixture is fermented at 53 degrees C for 10 hours, where food preservative is added before 30 minutes to fermentation completion time. The fermented product is filtered to remove impurities and transferred to the storage tank. Chlorine dioxide is supplied to the storage tank in a ratio of 1:1, stirred for 5 hours, followed by fermenting the stirred mixture, filtering, cooling to 20 degrees C and packing cooled product to obtain finished product.
