Vermicompst is a rich source of vitamins and growth hormones and contains most nutrients in plant available form. Ten adult earthworms (Eudrilus eugeniae) were cultured for three (3) months and three (3) weeks in sack made from old window mosquito net. The resultant product at harvest – vermicompost made of mostly worm casts was used to incubate sandy and clay soils respectively at the ratio of 50g: 300g for two (2) months and replicated five (5) times. The results of  the study shows that the produced vermicompost enriched the two types of soil with favourable pH level, high content of P, Ca, Mg and OM. Available P, pH level, Ca, Mg and OM were significantly (P < 0.05 ) increased and varied among the treatments. Exch. K and microbial biomass (MB) result showed higher value in clay while sand recorded higher value in N, Na and exchangeable acidity (EA). The findings of this study are of evidence that vermicompost improved the fertility of the soils by releasing mineral elements in the forms that are available for uptake of crops.
