We all know the earthworms found in our soils. The worm converts crop residues and organic materials from fallen trees into small pellets that serve as natural manure for plants. Earthworms are also useful for producing a better harvest without the help of a tractor. The worm helps to maintain the long-term durability of the physical, chemical and biological properties of the soil, as well as the soil fertility capacity. The earthworm uses decomposable organic waste as food. 5-10% of the food consumed is absorbed by the body cells of the worm and the remainder of this food is excreted in the form of pellets called Vermicompost. The breeding of the worm is known as vermiculture and, in the controlled state, the process of producing fertilizer by raising the worm is known as vermicompost.
Advantages and benefits of Vermicompost
Below is a list of the benefits of using vermicompost in your growing soils.
- The vermicompost is rich in all the essential nutrients for the plant. It allows excellent growth of plants, encourages the growth of new leaves and improves the quality and shelf life of the products.
- Improves the growth and quality of the plant.
- It is easy to manipulate the vermicompost and apply it, without bad odor.
- It promotes the fertility power of the soil as well as its structure.
- It improves the drainage power (water retention capacity) of the soil.
- The vermicompost is filled with earthworm cocoons, which helps to increase the activity of worms in the soil and also increases the population of worms in the soil.
- Vermicompost is completely free of weed seeds, toxic elements, pathogens and similar factors.
- Vermicompost is rich in enzymes, essential vitamins and hormones such as auxins, Gibberellins, etc.
- The use of vermicompost is useful to prevent soil erosion.
- The nutrient content of vermicompost is higher than that of traditional compost.
- Vermicompost hosts some microbial populations that contribute to nitrogen fixation in soil and to the « P » dissolving.
- The percentage of N: P: K in Vermicompost is greater than that of bacterial compost.
Chemical Composition of the Vermicompost
The chemical composition depends mainly on the waste naturedes, moisture, the source of the raw materials. In Vermicompost, the NPK ratio is more important than in ordinary compost. It contains all the nutrients necessary for the good growth of a plant. It contains 5 times more nitrogen than farm manure, 8 times more phosphorus, 11 times more potash and 3 times magnesium. Thus, its use is preferable to farm manure.
Nutrient content of Vermicompost
The nutrients it contains are entirely dependent on the degradable waste used to prepare the compost. The better the quality of the components, the better the quality of the compost. Heterogeneous waste is preferable to homogeneous waste as it provides a wide range of nutrients.
