A recent study in the savanna suggested that the surface soils might be contaminated with Ti, V, U and Th because of increasing phosphate fertilizer applications. In this study, we determined the dynamics of Ga, V, U, Nb, Y, La, Ce and Nd in a savanna soil that has received NPK fertilizers, farmyard manure (FYM) and FYM + NPK for 50 years using an adjacent uncultivated or native site as a reference. The concentrations of the elements in the soils were determined by X-ray fluorescence. Mass… CONTINUE READING
