An Overview: Organic Waste Management by Earthworm

Abstract

Vermicomposting is a biotechnological process, in which organic materials converted as valuable product by earthworms. The nutrient profi le of vermicompost is higher than traditional compost. The vermicompost alters the soil fertility in different ways, such as better aeration, porosity, bulk density, water holding capacity, pH, electrical conductivity, nitrogen, phosphorous and potassium content. The application of the vermicompost is enriches the soil microorganism, plant growth (size of leaf, height, width and weight) and nutrient content of the yield. The high concentrations of vermicompost may delay plant growth due to the concentration of soluble salts. As a result, vermicomposts should be applied at required quantity to produced higher yield. In this overview describe about the organic waste management, vermicompost, earthworms species and economical importance of the vermicompost.

Improvement of dragonhead (Dracocephalum moldavica L.) yield quality through a coupled intercropping system and vermicompost application along with maintenance of soil microbial activity

“…The higher content of macroand micro-elements compared with other organic composts is another benefit for the usage of vermicompost (Timsina, 2018). In addition, vermicompost application in agricultural systems enhances the activity of hormones such as auxin and cytokinin and provides optimal conditions for root growth (Rakkini, Vincent, Kumar, & Baskar, 2018;Zaremanesh, Nasiri, & Amiri, 2017). The organic fertilizer application in intercropping systems is expected to ensure the viability of the systems and to increase the quantitative and qualitative yield of the companion plants, improving the uptake of nutrients and reducing the use of chemical fertilizers.…”
