Organic Farming :: Composting Techniques - Vermi-composting
  • Vermicomposting {Asked JRF Agronomy & BHU GA }
    • is a process of degradation of organic wastes by earthworms.
  • The species like Eisenia foetida and Eudrilus eugeniae are effective in converting the agricultural wastes into compost. {Asked JRF Plant sc 2017 }
  • Selection of suitable earthworm  used for vermicompost production
    • African earthworm : Eudrillus engenial 
    • Red worms : Eisenia foetida
    • Asia worm : Peronyx excavatus {Source: https://www.agricoachingdelhi.in/}



  •  Most common available nutrients in vermicompost is as follows 
    • Organic carbon = 9.5 – 17.98%
    • Nitrogen = 0.5 – 1.50% {Asked in JRF Agronomy 2016 & & BHU GA }
    • Phosphorous = 0.1 – 0.30%
    • Potassium = 0.15 – 0.56%

  •  Advantages of vermicompost
  • 1. Vermicompost is rich in all essential plant nutrients.
  • 2. Vermicompost is free from pathogens, toxic elements, weed seeds etc.
  • 3. Vermicompost minimizes the incidence of pest and diseases.
  • 4. Vermicompost is free flowing, easy to apply, handle and store and does not have bad odour.
  • 5. It improves soil structure, texture, aeration, and waterholding capacity and prevents soil erosion.
  • 6. Vermicompost is rich in beneficial micro flora such as a fixers, P- solubilizers, cellulose decomposing micro-flora etc in addition to improve soil environment. {Asked in JRF Agronomy& IBPS AFO }
  • 7. Vermicompost contains earthworm cocoons and increases the population and activity of earthworm in the soil.
  • 8. It neutralizes the soil protection.
  • 9. It prevents nutrient losses and increases the use efficiency of chemical fertilizers.
  • 10. Provides excellent effect on overall plant growth, encourages the growth of new shoots / leaves and improves the quality and shelf life of the produce.
