Vermiwash: A Low-Cost and Eco-Friendly Liquid Fertilizer

The excessive use of chemical fertilizers in Nepalese agriculture threatens crop production and environmental health, adversely impacting soil, water quality, and human health. In this context, vermiwash emerges as an effective, cost-efficient, and organic alternative. Derived from the interaction of water with earthworms and organic waste, vermiwash serves as a nutrient-rich liquid fertilizer that enhances soil health, promotes plant growth, and boosts crop yields. The process of making vermiwash involves a double filtration system, where organic materials, cattle dung, and earthworms are used to produce a liquid rich in essential nutrients and beneficial microorganisms. The nutrient composition of vermiwash is beneficial for various crops, including cauliflower, tomatoes, and leafy greens.
