How is organic liquid fertilizer made? Detailed method and step-by-step explanation

1. Clean a large plastic barrel or water vat (100 kg) with diluted bleach solution, then rinse off the bleach with clean water. 2. After filling halfway with water, pour in molasses equal to 5% to 10% of the total water volume (5 to 10 kg), and stir vigorously so the molasses dissolves completely in the water. 3. Add 300 g to 1 kg of Lan Shijie "Mandian No. 18" liquid, equal to 1/300 of the total water volume. 4. Add organic materials and stir evenly to dissolve them. If insoluble organic matter is used, the amount added should be based on maintaining flowability; too much will create anaerobic conditions and cause failure. 5. Use a goldfish air pump to send air into the bottom of the barrel (a large screw nut can be used as a "sinker" to make the air tube sink to the bottom), and add an air stone to make the bubbles finer. If using a large water barrel of over 200 kg, use a three-pressure machine to supply air, and it is best to additionally install a time-controlled solenoid valve for intermittent aeration. 6. When using insoluble organic raw fertilizer or a barrel of over 1000 kg, an electric spiral stirrer must be used to stir intermittently. 7. Cover and tie tightly with clean cloth to prevent insects from entering. 8. After about one week of fermentation, a large amount of bubbles will be produced. Wait until foaming stops (after about three weeks) and it is ready to use. At this time it should have a fragrant, mellow, cleanly sour sauce-like smell, and it can continue to be used for one or two months.
