A method for producing a natural liquid fertilizer is provided to allow agricultural crops to absorb nutrients more easily, and to realize herbicidal, sterilizing and insecticidal effects in addition to a fertilizing effect. A method for producing a natural liquid fertilizer comprises the steps of: (a) introducing 1-5 wt% of rice bran and 5-20 wt% of syrup into 75-94 wt% of water, and carrying out fermentation at 30-60 deg.C under an aerobic condition for 10-40 days; (b) introducing 5-20 wt% of the fermented product of step (a), 5-20 wt% of spirit and 5-20 wt% of syrup into 40-70 wt% of water, and carrying out additional fermentation at 30-60 deg.C for 5-20 days; and (c) introducing 15-30 parts by weight of the fermented product of step (a), 20-40 parts by weight of the fermented product of step (b), 20-40 parts by weight of bamboo vinegar, 0.8-2 parts by weight of syrup and 1-5 parts by weight of rice bran into 100 parts by weight of water, and carrying out final fermentation at 30-60 deg.C for 5-20 days. Further, the last pH of fermented product performed through the step(c) is 3.5 to 4.5. |
