Vermicompost Preparation Method
Vermicompost is important to improve soil and crop growth. The main function of the earthworm is to thoroughly mix the organic substances, humus, and soil, and to spread the mixture into different layers of the soil. As a result, the water retention capacity of the soil increases. The earthworm excreta contains nitrogen, phosphorous, potash, calcium, and micronutrients. It helps to maintain the correct pH level of the soil.
Selection of Earthworms:
Earthworms in the group of phytophagous, epigeic or humus formers successfully produce vermicompost. On the other hand, endogetic, geophagous earthworms that live deep in the soil are not useful for making vermicompost.
Preparation of Vermicompost:
• Dung, leftover cattle feed, twigs, and crop cuttings should be half decomposed. Make a bed-like structure on the ground surface; do not make a pit.
• Put a 2-3 inches thick layer of slowly decomposing organic substances (sheath, dried leaves, crop cuttings, and others). Add earthworms to it. Then cover this bed with a gunny cloth.
• Control bed temperature from 25 to 28 degrees Celsius. The pH should be kept up to 6.5 to 7.5. Moisture should be between 45% and 50%.
• The bed should be under the shelter to prepare vermicompost.
• Lumps of soil in the bed should be crushed by hand, and the material in the bed should be moved upside down once a week.
• A tea powder like compost will be ready within a month or a little more. Separate the compost.
• Water should not be given in the worm bed for eight days before drawing the ready compost. Keep small compost hips prepared so that earthworms move to the bottom of the bed.
• Separate the vermicompost and the uncomposed parts should be returned to the worms. Pickax, excavator, and shovel may not be used when separating the vermicompost. This will not hurt the earthworms.
