Abstract

This study was carried out to evaluate the physicochemical properties of topsoil from forest development area. The results of physicochemical properties of topsoil from forest development area shown on the average loamy sand~sandy clay loam in soil texture, 5.3~7.1 in pH, 0.02~0.18 dS/m in EC, 0.7~1.8% in OM, 0.03~0.11% in T-N, 11~15 $cmol^+/kg$ in CEC, 0.02~0.04 $cmol^+/kg$ in $K^+$, 4.51~8.18 $cmol^+/kg$ in $Ca^{2+}$, 0.93~2.77 $cmol^+/kg$ in $Mg^{2+}$, 6~49 mg/kg in available phosphate. And the results of physicochemical properties of topsoil from forest non-development area shown on the average sandy loam~sandy clay loam in soil texture, 4.4~5.3 in pH, 0.03~0.05 dS/m in EC, 3.1~4.6% in OM, 0.13~0.23% in T-N, 14~18 $cmol^+/kg$ in CEC, 0.02~0.04 $cmol^+/kg$ in $K^+$, 0.78~3.82 $cmol^+/kg$ in $Ca^{2+}$, 0.29~1.31 $cmol^+/kg$ in $Mg^{2+}$, 3~31 mg/kg in Av. $P_2O_5$. On the other hand, forest development area of topsoil sand content higher than 8~18% sand content than the forest non-development area. This trend is thought to be the absence of topsoil management development projects. Consequently, the results suggested a high potential of recycling of the topsoil from forest non-development area for planting soil. Therefore, in construction of the conservation and management of topsoil from forest non-development area is very important.
