It has been proved that vermicompost has more nutrients than compost produced by any other composting methods. It even surpasses commercial compost with added nutrients, however, it requires adjustment for pH and magnesium. On the other hand, it has been revealed that home made vermicompost is inferior to municipal compost in terms of soil microbial activity and microbial biomass. Furthermore, one study has shown that the differences between various composts largely depend on the feeding material that has been used, so composts made from different materials cannot be equally compared and no generalizations can be made. Vermicompost is rich in micro-organisms which convert nutrients in the soil into plant-available forms. Contrary to other types of compost, vermicompost has worm mucus. It retains moisture better than plain soil and prevents nutrients from washing away after the first watering.
