An improved system (100) for processing a liquid manure and producing organic fertilizer includes equipment (101) for separating various components of the liquid manure having different nitrogen to phosphorous ratios and equipment (120) for mixing these components so as to produce an organic fertilizer with a predetermined nitrogen to phosphorus ratio. The system (100) includes equipment (106) for separating a first manure component A that contains about 15 percent soluble phosphorus and about 20 percent soluble nitrogen, equipment (107) for adding a flocculant material to the liquid manure aqueous solution, equipment (108) for separating a second manure component B that contains about 40 percent partially soluble phosphorus and about 30 percent partially soluble nitrogen, equipment (110) for performing direct current electrocoagulation cleaning of the liquid manure aqueous solution and separating a third manure component C that contains about 45 non- soluble phosphorus and about 10 percent non-soluble nitrogen and equipment (112) for performing clarifying cleaning of the liquid manure aqueous solution and separating a fourth manure component D that contains about 40 percent non- soluble nitrogen and no phosphorous.
