Abstract

Soil pH has become acidic in large areas of tea plantations in Iran (pH<4). The main reasons for this change are: rainfall, leaching, acidic parent materials, and use of chemical fertilizer containing ammonium ion for a long period. High acidity of soil causes deficiency and toxicity of some nutrients, nematode spreading and decreasing in yield. Regard to importance of pH of soil and its optimum value for tea growth (pH=5-5.5), it is necessary to increase the pH level in soil using suitable and available amendments. The aim of this study was changing the pH to optimum level in soil. Two kinds of calcareous materials (i.e. local limestone and seashell) were applied to increase soil pH in tea plantations. The amount of lime requirement was calculated using Foth equation, [pH 24=187-0.3CEC-HSP] with respect to provide optimum value of pH and CEC of soil. The study was carried out in a factorial experiment as a completely randomized design. The amounts of limestone powder were 1.34, 2.69, 4.07 and 8.14 gr per kg soil and for sea shell powder were 0.95, 1.89, 2.87 and 5.74 gr per kg of soil for increasing the pH of soil from 3.5 to 3.9, 4.4, 4.8 and 6.1, respectively. The pH was measured 1,2,3 and 6 months after application of lime in each pot. The results showed that both compounds increased the soil pH to optimum value in an interval of 1 to 6 months and there was no difference between the treatments.
