Vermicomposting is a process using worms to convert organic materials like food scraps into a nutrient-rich humus that improves soil structure, aeration, drainage, and water retention. It produces vermicompost which is an excellent organic fertilizer and soil conditioner used in sustainable farming. However, building a vermicompost bin requires patience as it can take worms six months to fully break down materials, and bins require regular maintenance to avoid odors, pests, and pathogens during the processing time.
