Abstract

Hydraulic conductivity of a tea growing soil depends on the soil structure.The principal objective of this work was to investigate the influences of soil texture and total organic matter content on hydraulic conductivity for the tea growing soils of Dibrugarh district. Thirty composite soil samples were randomly collected from the top soil (0-20 cm) from the ten tea estates. The samples were analysed for texture, total organic matter content and hydraulic conductivity. The texture of the soil samples found to be sandy clay loam, sandy loam and sandy clay. The total organic matter content varied from 2.28 to 3.72 % with mean value of 3.04 %. The hydraulic conductivity varied from 0.234 to 0.386 cm/min with mean value of 0.311cm/min.The results showed that the soil samples have sufficient amount of total organic matter. It was concluded that soil texture and soil organic matter content had influenced on hydraulic conductivity of the tea growing soil. It was suggested that high concentration of organic matter on soil should be incorporated to the soils with improving hydraulic conductivity. A significance positive relationship was observed between hydraulic conductivity with organic matter content and sand, while, a negative relationship was found with clay content.

Key words: Hydraulic conductivity, clay content, silt content, sand content and total organic matter content.
