Generation of enormous volume of wastes from mining activities that pollute the surrounding environment is still a global challenge. Pollution emanating from the wastes usually leads to loss of vegetation cover whose re-establishment through phytoremediation requires an assemblage of the physico-chemical data of the soils on which designing of remediation strategies are based. Thus, the physico-chemical characterisation of the tailings and pyrite soils was conducted following standard procedures and their variation across depths, seasons and earmarked zones evaluated. Both copper tailings and pyrite soils were extremely acidic, deficient in total nitrogen and available phosphorous and heavily polluted with Cu, Co and Ni relative to the unpolluted soils. The distribution of available P, total nitrogen and heavy metals was heterogenous varying significantly across zones, depths and not significantly across seasons except available phosphorous. Re-adjustment of the physico-chemical parameters to levels that permit seedling establishment and growth through application of amendment materials is a pre-requisite for any successful phytoremediation. Evenness in their application may be hard to achieve leading to emergence of red spots hence a need for close monitoring during the phytoremediation programme.
