Soil Quality Study To compare the growth of lemongrass in an integrated plantation area, Nong Bo
Sub-district, Yan Ta Khao District, Trang Province. The objective was to study soil quality in relation to the
growth of lemongrass by measuring soil quality according to GLOBE protocols, including soil temperature,
pH, soil structure, soil texture, soil consistency, and soil fertility affecting the biomass of lemongrass. It was
found that Area 1 had a higher soil temperature than Area 2. The soil pH in Area 1 was lower than that of
Area 2. The soil structure in Area 1 and Area 2 was similar, and the soil texture in both areas was the same.
The soil consistency in Area 1 was "very firm," while Area 2 was "firm." These factors affected the growth of
lemongrass in the two areas differently, resulting in Area 1 having a lower biomass than Area 2.
