Vermicompost are the waste generated by the earthworms that are rich in NPK & other essential minerals required for the growth of plants. This in fact rejuvenate the soil
Vermicomposting is the process of turning organic waste into worm castings. The worm castings are very important to the fertility of the soil. The castings contain high amounts of nitrogen, potassium, phosphorus, calcium, and magnesium. Castings contain: 5 times the available nitrogen, 7 times the available potash, and 1 ½ times more calcium than found in good topsoil. Several researchers have demonstrated that earthworm castings have excellent aeration, porosity, structure, drainage, and moisture-holding capacity. The content of the earthworm castings, along with the natural tillage by the worms burrowing action, enhances the permeability of water in the soil. Worm castings can hold close to nine times their weight in water. “Vermiconversion,” or using earthworms to convert waste into soil additives, has been done on a relatively small scale for some time. A recommended rate of vermicompost application is 15-20 percent.
Advantages of vermicompost
- increase soil dynamics
- decrease nutrient leaching
- improve soil water retention ability
- improve plant germination
- promote early root and leaf development
- accelerate growth
- increase yield
- offer disease suppressive qualities.
