Abstract

Soil macronutrients (N,P, and K) are essential to tea plants. The excessive application of commercial N, P, and K fertilizers on soil to high yield of tea can be increase the potentially hazardous element into the field, which has been cited as a source of contamination of surface and ground water. In this study, thirty composite soil samples were randomly collected from the top soil (0-20 cm) in some selected tea growing soils from the ten tea estates in Sivasagar district. The samples were analyzed for physio-chemical properties and total concentration of N, P and K. Soil textures were classified as sandy clay loam, sandy loam and sandy clay. The PH ranged from 4.28 to 5.36. The total organic matter content ranged from 2.18 to 3.12 % with mean value of 2.71 %. The nitrogen ranged from 0.124 to 0.242 mg/kg with a mean value of 0.179 mg/kg, phosphorus ranged from 43.56 to 154.38 mg/kg with a mean value of 103.06 mg/kg and potassium ranged from 2.32 to 3.08 meq/kg with a mean value of 2.66 meq/kg. Soil samples were found sufficient amount of total organic matter, nitrogen, phosphorous and potassium. Significance positive correlations were found to exist between PH, organic matter content and clay with total N, P and K status of soil under study.
