Soil and leaf samples were collected from the ten tea estates in the month of December every year during the period of 2007 to 2009. Soil samples were taken from 0 to 30 cm depth. Leaf samples (two apical leaves and the bud) were collected from the same plots as the soil samples. According to the results, Mn, Fe, Cu and Zn concentration of soil varied within the range of 118.53 to 420.57; 89.34 to 307.72; 12.73 to 26.32 and 21.43 to 45.28 mg/kg respectively. Mn, Fe,Cu and Zn concentration of leaf samples were ranged as 224.36 to 568.64; 212.85 to 546.42; 14.34 to 29.78 and 24.82 to 58.26 mg/kg respectively. From the study it was found that the micronutrients concentration of the tea leaves was higher than the concentration of the tea soil. It was also detected that there was no micronutrients deficiency in the study area, when mean values for both soil and leaves samples were taken into consideration.
