Physicochemical Analysis and Status of NPK in Three Different Forms of Vermicompost Prepared from Water Hyacinth Near Tapi Region in Surat

Abstract

Vermicomposting is a sustainable and environmentally friendly way to handle organic waste that improves soil fertility by enriching it with nutrients. In this research, three distinct types of vermicompost made from water hyacinth (Eichhornia crassipes) gathered close to the Tapi area in Surat will be examined for their physicochemical characteristics and the levels of nitrogen (N), phosphorous (P), and potassium (K). Eisenia fetida was used in the vermicomposting process, and three different formulations were used, each of which included water hyacinth and other organic ingredients to maximise decomposition. Compost maturity and quality were evaluated using physicochemical criteria, such as pH, electrical conductivity, organic carbon, moisture content, and C/N ratio. To ascertain each compost type's capacity for nitrogen augmentation, the NPK content was examined using accepted analytical techniques. Significant differences in nutritional content were shown by the data, with the vermicompost enhanced with cow dung showing the highest NPK levels. The research emphasises how vermicomposting may effectively transform invasive aquatic weeds into organic fertilisers that are high in nutrients, hence encouraging sustainable farming methods in the Tapi area.
