While both vermicompost and regular compost have their own merits and limitations, it is a general belief that vermicompost is better than regular compost. Some of these merits and limitations are listed below:

  • The enzymatic response is greater in vermicompost compared to regular compost.
  • Vermicomposting has a higher rate of microbial activity compared to regular compost.
  • Size of vermicompost is less than 20 microns.
  • Compared to regular compost, vermicompost contains more nutrients. It is concentrated with high levels of phosphorous and nitrogen.
  • Compost Tea is formed when the liquid beneath vermicompost bin is diluted with water. This provides a nutrient rich drink for established plants. Regular composting does not form any such liquid.

Other differences between vermicompost and regular composts are listed as follows:
