Abstract:
PCT No. PCT/BE93/00025 Sec. 371 Date Jan. 4, 1995 Sec. 102(e) Date Jan. 4, 1995 PCT Filed May 12, 1993 PCT Pub. No. WO93/23349 PCT Pub. Date Nov. 25, 1993A method for processing a liquid nitrogen-rich organic waste product, in particular a manure product, to an aqueous fertilizer solution utilizes a biological conversion process so as to obtain a biologically stable fertilizer solution. This conversion process includes at least a nitrification step wherein nitrifiable ammonium nitrogen is converted in nitrate nitrogen and, only if the fraction to be nitrified has a too high content of nitrifiable nitrogen, a denitrification step. The fertilizer solution is separated off after the nitrification step so that it contains nitrate and only up to 150 mg NH4+-N/l at most. The fertilizer solution can be used as leaf nutrition or in a hydroponic system.
