Preparation of Bio-organic Fertilizer with Solid-fermentation Distiller's Grains by Two-step Fermentation
Bio-organic fertilizer,produced by two step fermentation of solid-fermentation distiller's grains,its pH value,the content of effective phosphorus,organic matter and total nitrogen content,and its performance were measured and analysed.The facts proved that distiller's grains inoculating with functional microbes to produce bio-organic fertilizer through two-step fermentation was feasible in practice.Furthermore,the technology of two-step fermentation for the preparation ofbio-organic fertilizer was designed..
