This research aimed to study soil quality and the carbon sequestration capacity of mango trees in Phak Mai Subdistrict, Huai Thap Than District, Sisaket Province, with a focus on Phak Mai Yai Village and Krasang Village. The study compared soil quality factors—such as pH value, temperature, and major nutrients (nitrogen, phosphorus, and potassium)—with the amount of carbon sequestered by mango trees. The results showed that Phak Mai Yai Village had a soil pH of 5 and was able to sequester 61.61 kilograms of carbon dioxide, while Krasang Village had a soil pH of 8 and sequestered only 32.99 kilograms of carbon dioxide. Although both areas had low levels of major nutrients, the acidic soil conditions in Phak Mai Yai Village may have positively influenced the absorption of certain nutrients and supported better mango tree growth. The findings indicate a relationship between soil quality and carbon sequestration capacity, which can be applied to sustainable agricultural land management planning and to support the reduction of greenhouse gas emissions at the community level.
Keywords: Soil quality, carbon sequestration, and soil nutrients (e.g., N, P, K)
