Chop or blend the kitchen waste and crush the charcoal into small pieces. Mix all wet ingredients together and mix the dry ingredients separately, then combine both, mixing thoroughly. Add water until the mixture is moist but not soggy, seal it tightly in an airtight container or thick plastic bag, and let it ferment for two weeks in a cool, shaded place. After fermentation, mix it with garden soil at a ratio of 1:1 to 1:10, water well, add earthworms, and keep the soil moist during the first season. This improves soil fertility naturally and boosts microbial life and worm activity. Micro organisms like beneficial bacteria, fungi, microbes and worms need a moist environment to survive. This supports stronger plant growth and higher yields.
