The results indicate that CaCO3 in the clay fraction of Egytian soils has a greater affinity for Zn than silicate clay. Moreover, in the presence of carbonate, Zn was retained more tightly to form complexes hard to be extracted and, thus, relatively unavailable for plant uptake. Therefore, CaCO, plays an important role in zinc deficiency which is commonly found in calcareous soils.
