3.2. Soil properties of bench terraces
Reddish colored soils covered the ground in Pang
Prarachatan village. The soil properties of the bench terraces
are summarized in Table 5. The soil samples taken from the
terraces were light clay (LiC) according to the International
Soil Science Society Classification (Hillel, 1971). The
dispersion ratio ranged from 21% to 29%, indicating that
the soils were erosive (Middleton, 1930).
