Comparative analysis of macro and micro nutrients of bio waste, compost and vermicompost (using indigenous Lumbricus terrestris) of solanum melongena (fruit) waste. Journal of Scientific and Engineering Research, 4 (3), 102-1042394-2630https://repository.futo.edu.ng/handle/20.500.14562/2807This work was done in collaboration with a FUTO staffThere is global demand for organic food due to perceived effects of foods produced with synthetic fertilizers and chemical pesticides. Owing to this, a comparative analysis of macro and micro nutrients in bio waste, compost and vermicompost of Solanum melongena waste were done to ascertain their efficiencies in organic farming. The vermicompost was done with indigenous Lumbricus terrestris (earth worm) in an earthen pot with mixture of Solanum melongena and cow dung in the ratio of 5:1. The biowaste was done in a similar way with exception of cow dung and Lumbricus terrestris. The compost was done similarly with the exception of Lumbricus terrestris. Results showed that macro nutrients (N, P, K, Ca and Mg) and micro nutrients (Fe, Cu, Zn, and Mn) followed this trend; Vermicompost ˃ compost ˃ bio waste, with exception of zinc. Vermicompost and compost of Solanum melongena can be utilized as organic fertilizer in the production of organic foods.enAttribution-NonCommercial-ShareAlike 4.0 InternationalVermicompostingsolanum melongenabiowasteorganic foodDepartment of ChemistryArticle
