The invention discloses an
organic fertilizer composition taking fermented
sludge as a matrix. The
organic fertilizer composition is prepared from a
sludge matrix, a structural auxiliary material and a functional
biological agent, wherein the weight ratio of each component is as follows: 45-100 parts of the decomposed
sludge, 15-50 parts of the structural auxiliary material and 0.1-2.0 parts of the functional
biological agent; the
water content of the sludge matrix is lower than 30%, the sludge matrix is sludge subjected to harmless
fermentation treatment, and the functional
biological agent comprises
nitrogen fixation,
phosphate solubilizing,
potassium solubilizing and microbial
flora; the structural auxiliary material is a mixture of agricultural organic waste and an inorganic mineral conditioner. Compared with the prior art, the
organic fertilizer composition with the fermented sludge as the matrix and the
processing technology of the organic
fertilizer composition have the advantages that the harmless degree is high, the
physical property is excellent, functional viable
bacteria are rich, and efficient
resource utilization of the sludge is achieved.
