Original Abstract Submitted
A method for preparing an adjustable organic fertilizer is provided. The method includes providing a ratio of nitrogen, phosphorus, and potassium required for a target crop and collecting a plurality of wastes. The method includes categorizing the fertilizer concentrations of the same type of feeding substrates within the wastes separately, and adjusting the composition of the categorized wastes to form a composite feeding substrate according to the ratio of nitrogen, phosphorus, and potassium required for the target crop. The method includes subjecting the composite feeding substrate to an anaerobic fermentation process. The anaerobic fermentation process includes introducing the composite feeding substrate into an acidification tank to obtain a first mixture and introducing the first mixture into a methanogenesis tank to obtain a second mixture. The method further includes separating the second mixture to obtain liquid digestate and solid digestate, wherein the solid digestate serves as an organic fertilizer.
