Abstract

The study of soil fertility and the assessment of carbon storage in oil palm plantations, rubber plantations, home gardens, and remnant forests within the Khlong Khanan sub-district, Nuea Khlong district, Krabi province aimed to examine the chemical and physical properties of the soil, evaluate carbon storage, and analyze the relationship between soil factors under different land use types. Sampling plots measuring 10x10 m were established, and soil samples were collected at depths of 0–5 cm and 20–25 cm for each depth, five subsamples were composited into one sample, resulting in two samples per plot, with three plots per land use type, giving a total of 24 samples for the analysis of soil chemical properties. Soil samples for physical properties were collected using a soil core. Additional plots measuring 40x40 m were established, and tree species composition was recorded to evaluate carbon storage. The study areas consisted of three plots [3 rai (0.48 ha)] each for oil palm plantations, rubber plantations, and home gardens, along with 1 rai (0.16 ha) of remnant forest. The results revealed that soil fertility at a depth of 0–5 cm was higher than that at 20–25 cm, with a tendency to decrease as soil depth increased. The physical properties of the soil in monoculture areas were harder and shallower compared to those in agroforestry areas. The surface soil at 0–5 cm was predominantly sandy loam, while the subsurface soil at 20–25 cm was sandy clay loam. Soil moisture and bulk density values were similar across the land use types, indicating no statistically significant differences. The amount of carbon storage varied among the different land use types. Therefore, most land use guidelines emphasized maximizing land use efficiency in conjunction with conservation and restoration. The findings could be utilized as guidelines for managing agricultural and forest areas toward appropriate and sustainable practices.
