This research aims to study the effects of soil quality on the carbon storage of seagrass in Pak Klong Beach and Ao Kham, Trang. Two study sites were defined: Pak Klong Beach and
Ao Kham Beach. collected soil and seagrass samples in both sites by placing specific random quadrats in areas with 50–75% dense seagrass, divided into 4 groups, with Group 1–3 types randomly separated according to the type of sea grass, including Enhalus acoroides,
Halophila major, and Cymodocea rotundata. As for the fourth group, the area with 3 sea grass species was randomly grouped together. Analyze the soil quality and take seagrasses to compare the carbon storage of each type of seagrass at both sites and analyze the amount of carbon storage. The results of the study found that soil quality affects seagrass carbon storage. If the organic matter content is high, it will also lead to a large amount of carbon storage, and the carbon storage of Ao Kham has a higher amount of carbon storage from seagrass than Pak Klong Beach. The carbon storage of each type of seagrass is different. And the species with the most carbon storage was Enhalus acoroides, followed by Cymodocea rotundata and Halophila major, respectively. As for the seagrass that lives in groups, it can store more carbon than any single seagrass habitat. And the carbon storage of seagrass in the underground part is higher than in the above-ground part.
