Abstract: A liquid fertilizer is produced from off-gassed ammonia resulting from the processing of animal waste materials, particular animal manure. The vaporized ammonia is generated primarily by heating the animal waste materials and capturing the resulting vapors and particulate materials. The ammonia vapors and particles are removed from the gas stream through a scrubbing operation, which creates an ammonium-enriched liquid stream that can be concentrated into an organic fertilizer having a high-nitrogen content.

Abstract: Bioactive fertilizers with improved extended phosphorous availability comprise fractured animal manure waste blended with at least potassium, phosphorus and calcium, in a dried prill form, wherein the calcium is substantially bound up with phosphorus in a mineral complex and that comprises soluble organic carbon in a form that readily dissolves upon application to soil and that can bind soluble calcium in soil. Methods are also provided that fracture chicken waste with a kinetic mixer, the mixer comprising a motor operably connected to a vertical shaft within a column, the vertical shaft having a feedstock entry port at the top surface; generally flat blades extending radially from the shaft with at least one set of an even number of blades spaced apart radially at a defined distance along the vertical axis; and an exit at the shaft bottom to allow fractured feedstock to exit to a mixer; wherein the column comprises one or more walls surrounding the shaft with attached blades.
