Abstract

Most of the soil samples were below saturated soil water content. The presence of organic matter in most of the samples was very low (<2%). The particle distribution analysis showed that the presence of sandy size was higher than silt and clay portions. The presence of highly sand can decrease the water retention ability of soils. The classification of soil textures consisted of clay, silty clay and silty clayey loam. The analysed soil samples were acidic (<pH5) with low ferum oxide content (0.2%-3.7%). The acidic of weathered metasediments  of  graphitic  phylite  and  schist  caused  the  dissolution  of  ferum oxide. Based  on  the coefficients of clay dispersion suggested that most of the soil aggregate structure of the soil samples were categorised as stable.

 

Keywords: Clay, texture, metasediment, clay dispersion
