The states of Kedah and Kelantan of Malaysia are the main paddy growing areas of the country. Fifteen soil series from these states were selected for the determination of Zn<sup>2+</sup>, Cu<sup>2+</sup>, Mn<sup>2+</sup> and Fe<sup>2+</sup> status and some other physico-chemical properties. Soil samples were collected from three different locations of same soil series at the depths of 0-15, 15-30 and 30-45 cm. All the soils were acidic and low in organic carbon and P, while their texture varied from clay loam to silty clay. Copper (Cu<sup>2+</sup>) and manganese (Mn<sup>2+</sup>) were moderate in status, and iron was high. Available soil Zn<sup>2+</sup> varied at different depths and locations for all the soil series (P<0.05); the top soils contained as high as 2.03 mg kg<sup>-1</sup> and the subsoils as low as 0.22 mg kg<sup>-1</sup>. Zinc concentration had negative correlation with Cu<sup>2+</sup> (r= -0.77*), P (r= -0.65*), Fe<sup>2+</sup> (r= -0.54*), Mn<sup>2+</sup> (r= -0.23*) and pH (r= -0.21*) and positive correlation with organic carbon (r = 0.41). This study shows that Zn<sup>2+</sup>, Cu<sup>2+</sup>, Mn<sup>2+</sup> and P status  of paddy growing soils of Malaysia is low, and this could possibly be one of the main reasons of low rice yield.</p>}, number={1}, journal={Pakistan Journal of Agriculture, Agricultural Engineering and Veterinary Sciences}, author={Hafeez, B. and Khanif, Y.
