With the aim of determining the nitrogen, phosphorus, potassium, calcium, magnesium, sulphur concentration of tea-farming soils and tea plant, 532 soil samples and 532 tea plant leave samples were taken simultaneously along East Black Sea Coastal Region considering the width of the tea cultivated areas (Artvin: 58 samples (10.90% of total), Rize: 361 (67.86 %), Trabzon: 101 (18.98% ), Giresun: 12 (2.26 %)).

At the end of the soil analysis, it was seen that total nitrogen concentration of tea-farming soils varied in the range 0.50-11.06 g/kg with a mean of 2.77 g/kg, plant available phosphorus: 1.11- 337.05 mg/kg with a mean of 45.49 mg/kg, plant available potassium: 12.60-3374.53 mg/kg with a mean of 203.90 mg/kg, plant available calcium: 17.18-50174.33 mg/kg with a mean of 1673.18 mg/kg, plant available magnessium: 6.30-4999.28 mg/kg with a mean of 215.97 mg/kg and plant available sulphur: 4.71-946.41mg/kg with a mean of 148.94 mg/kg. Considering analysis results, plant available sulphur concentration of the soil samples was found enough for the tea plant, however in 4.32% of the soil, nitrogen concentration; in 21,99 %, phosphorus concentration; in 37.40%, potassium concentration; in 70.11%, calcium concentration; in 75.00%, magnessium concentration were found insufficient. On the other hand, in 75.75% of the soil, nitrogen concentration and in 57.52 %, phosphorus concentration were excessively found.

It was determined that total nitrogen concentration of tea leaves taken from East Black Sea Region varied in the range 25.01-51.53 g/kg with a mean of 41.24 g/kg, phosphorus concentration: 0.06- 0.43 g/kg with a mean of 0.17 g/kg, potassium concentration: 0.08-3.46 g/kg with a mean of 0.94 g/kg, calcium concentration: 0.07-1.74 g/k with a mean of 0.61 g/kg and magnessium concentration: 0.04-0.57 mg/kg with a mean of 0.18 g/kg. At the end of the analysis, total nitrogen concentration was not enough in 3.46% of the tea leave samples, however it was found excessive in 30.65%. In 81.77% of tea leave samples phosphorus concentration, in 99.81%, pottassium concentration, in 17.48%, calcium concentration, in 36.09%, magnessium concentration were found insufficient.
