Soils polluted with heavy metals have become common across the globe especially in the heavy industrial areas. A number of anthropogenic activities lead to maximizing the soil contents of the heavy metals above their natural background levels. The elevated concentrations of heavy metals are detrimental to plant growth and may cause hazardous risks to animals and human. Therefore, this research work was conducted aiming at throwing some lights on chemical remediation (stabilization) of lead (Pb) as one of the wide spread contaminate of agricultural soils. To fulfill the objective of this work an incubation experiment was conducted on soils polluted, to different extents, with Pb owing to different anthropogenic sources. In this experiment the Pb-polluted soils were treated with either zeolite (at rates of 0,2,4 and 6%) and CaCO3 ( at rates of o and 5%),in this concern to fraction sizes of CaCO3 were investigated i.e. fine (0.02 -0.002mm) and coarse (2 -0.02mm). Regardless of soils contents of Pb and their variations in some properties, results revealed generally, the following: Zeolite reduce soil content of AB-DTPA extractable Pb and its effect seemed more obvious by increasing rate of the applied zeolite. Moreover, increasing period of incubation of zeolite was associated with progressive reduction in soils contents of Pb, however, the depressing effect of zeolite on soils content of AB-DTPA extractable Pb continued up to the 28th day of incubation beyond which contents of AB-DTPA extractable Pb increased
 Likewise, application of CaCO3 reduced extractable P
