Abstract:

The micronutrient zinc is required by rice in a small quantity, but its deficiency has an adverse effect on healthy crop growth and the yield may decrease up to 30%. 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 Zn2+, Cu2+, Mn2+ and Fe2+ 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 (Cu2+) and manganese (Mn2+) were moderate in status, and iron was high. Available soil Zn2+ varied at different depths and locations for all the soil series (P
