Increasing yield and quality of tea plant that is the lifestyle of The East Black Sea Region people is related to aware of importance of micro nutrient elements that found tea farming soils as well as macro nutrients. In this study, it is aimed to determine iron, copper, zinc and manganese concentrations of tea plant and farming soils. For this purpose, 532 soil and plant samples were taken simultaneously from different regions (Artvin, Rize, Trabzon and Giresun) related to distribution of tea plantations. In soil samples, available Fe concentration varied in the range of 0.56-407 mg kg-1 with a mean of 86.7 mg kg-1, Cu concentration varied in the range of 0.01-19.4 mg kg-1 with a mean of 1.44 mg kg-1, Zn concentration varied in the range of 0.03-44.9 mg kg-1 with a mean of 1.61 mg kg-1, Mn concentration varied in the range of 0.33-186 mg kg-1 with a mean of 29.3 mg kg-1. According to the results of the soil analysis, while plant available Fe and Mn concentrations were found to be sufficient, in 11.1 % of soils Cu, in 49.6 % of soil Zn concentration were found too few. In the tea leaves that taken simultaneously with the soil samples from the East Black Sea Region, it was determined that total Fe concentration varied in the range of 20.80-1931 mg kg-1 with a mean of 136 mg kg-1, total Cu concentration varied in the range of 0,62-25,7 mg kg-1 with a mean of 7.66 mg kg-1, total Zn concentration varied in the range of 0.98- 53.5 mg kg-1 with a mean of 12.7 mg kg-1, total Mn concentration varied in the range of 146-5013 mg kg-1 with a mean of 1608 mg kg-1. According to the results, in 98.9 % of leaf samples Fe concentration, in 97.0 % of leaf samples Cu concentration, in 97.6 % of leaf samples Zn concentration were found to be insufficient.
