Developing countries with inadequate waste disposal systemunit or regulatory process is at risk of metal land. The aim of thestudy is to access the suitability of soils around old Nekede roadin Owerri West L.G.A of Imo State in Nigeria. After the removalof the overlying waste soil samples were collected from five (5)different control points of open waste landfills (deposit point,North point, south point, east point and west point), 100m awayfrom each other and at a depth of three different depths (0-15cm, 15-30 cm and 30-45 m) on an open waste landfill using aDutch soil auger. The physicochemical parameters of the soilwere determined using standard laboratory methods, while, thediethylene triamine penta-acetic acid (DTPA) extraction methodwas used for Fe and Zn. The results were evaluated by ANOVA.Iron and zinc concentrations in deposit point with the depth of0-15 cm,15-30 cm, 30-45 cm, ranged from 202.85 mg kg-1, 164.47mg kg-1, and 131.33 mg kg-1. Hence, it falls within thepermissible range from 2760.1 to 2833.07 mg 100g-1; while, Zincranged from 147.5 mg kg-1, 67.22 mg kg-1, 26.13 mg kg-1, and fallswithin the permissible limits of 300 mg kg-1. The concentrationof heavy metals on under review was moderate and falls underthe permissible standard during the time of this study. It will besuggested that the land can adequately produce with or withoutadditional treatment. Crops such as cassava, plantain andbanana can be encouraged in such areas.
