ABSTRACT:
The invention relates to a nutrient rich humus material produced by a process wherein solids in an aqueous slurry of animal excrement are settled or precipitated in a solids ecoreactor, the slurry may be treated before and/or after settlement in the ecoreactor by passing to a bioreactor wherein soluble phosphorus may be precipitated with metallic salts, the slurry is aerobically and anaerobically treated to form an active biomass that actively bioconverts remaining soluble phosphorus, nitrogen and organics, and the aqueous slurry containing bioconverted phosphorus is recycled to said solids ecoreactor and/or discharged, and at least a portion of slurry is bioconverted and recovered as a beneficial humus material.
