The objective of this research is to study the relationship between soil quality and the amount of carbon absorption of Hevea Brasiliensis trees in the area of Palian District, Trang Province. Random soil samples were collected from soil structure at 10 locations in a soil sampling area of 1,600 square meters and used for analysis. physical soil properties Using methods for measuring environmental data according to GLOBE's measurement methods, including soil color, soil texture classification, soil structure, soil cohesion. and used to analyze soil chemical properties, including soil acidity and alkalinity, nutrients N, P, and K in soil, using field soil testing methods and kits. Measurements were made by measuring the height and circumference of the rubber trees, then using the data to calculate the biomass of the Hevea Brasiliensis trees and analyze the amount of carbon stored in the trees according to the principles of the allometry equation. From the study of soil depth in the upper soil area of the Hevea Brasiliensis plantation plots, it was found that the soil depth study in the upper area The part has a depth of more than 20 centimeters and has the characteristics of loose soil adhesion. It has a spherical structure. And the color of the soil is mostly dark brown. which is classified as loam soil The average pH was 5.7±0.48, the average soil moisture was 10.35±0.32%, and the average temperature was 29.54±0.62 (°C). From calculating the amount of carbon stored, the results of the study found that the amount of carbon storage in the research area 40x40 square meters has a carbon storage amount of 7,725.47 tons of carbon. In a total area of 4800 square meters, there is a carbon storage amount of 23,176.41 tons of carbon and an average of 103±41.04 tons of carbon per tree.
