This paper describes the study on the microbial organic fertilizer production process using vegetable waste and wood sawdust discarded from mushroom production. This process benefits many farmers and solves the environmental odor pollution from garbage leakage in the wholesale market The results showed that the second formula CT2 (treatment 2: mixing ratio C/N = 30-35 and initial moisture content 67-77 percent) was suitable for compo sting organic fertilizers (compost fertilizer with ratio C/N: 14.19). When composting with three biological products, compost fertilizers were obtained after 21 days and the best biological product was NOLASUB (ratio C/N=12.23). For pilot-scale (weight = 200 kg), after 21 days, formula with aerated system was better than non-aerated one, the obtained microbial organic fertilizers met the standard stipulated in the Circular No.36/2010/TT-BNNPTNT on June 24, 2010 promulgated by the Ministry of Agriculture and Rural Development. Survey on Brassica integrifolia found that productivities of the formulas with compost fertilizers were 2-3 times higher than the control one.
