Abstract
An area of 40.5 ha at UiTM Sarawak, Samarahan Campus farm was surveyed at a detailed level. There are three soil major groups, three soil families and six soil series identified in UiTM Sarawak, Samarahan campus. The three soil major groups are Red Yellow Podzolic (RYP), Gley and Organic. The three soil families are BEKENU and MERIT Family of RYP Group, BIJAT and TATAU Family of Gley Group and ANDERSON Family of Organic group. The soil series identified are Bekenu of BEKENU Family, Merit and Jakar of MERIT Family, Daro of BIJAT Family, Tatau of TATAU Family and Gadong of ANDERSON Family. The majority of the area is classified as having agriculture capability of Class 2t, 3te and 4te. Class 2t, 3te, 4te consist of Jakar, Merit and Bekenu series and which are restricted for agriculture due to the steepness of the slope. Class 3wi consists of Daro series soil where wetness and inundation hazard is a moderate limitation for agriculture use. Class 4fw consists of Tatau series soil which is not suitable for agriculture used due to serious fertility and serious wetness. Class 04go consists of Gadong series which is also not suitable for agricultural use due to high groundwater table and undecomposed organic surface layer.
Highlights
The Soil Classification System of Sarawak was updated in 1982 (Tie, 1982). The nomenculture of this Classification System was strongly influenced by the earlier soil classification system (Soil Survey Staff, 1966, Andriesse, 1972; Scott, 1973; and Lim, 1975); Soil Taxonomy (USDA, 1975} and by new finding on soils of Sarawak (Andriesse, 1975; Eilers and Loi, 1978; Loi, 1980; Lah 1980 and Teng 1981)
Soils occurring in the survey area are classified based on the current soil classification (Teng, 2004).The three soil major groups are Red Yellow Podzolic (RYP), Gley and Organic
The RYP soil group occurred on undulating hill comprising of Merit and Jakar series of MERIT Family and Bekenu series of BEKENU family
Summary
The Soil Classification System of Sarawak was updated in 1982 (Tie, 1982). UiTM Sarawak Samarahan campus is divided into three major physiographic types i.e. hilly areas, undulating areas and low lying areas such as alluvium and waterlogged peat swamp. According to the Sarawak Soil Classification System (Teng, 2004), the diagnostic horizons/characteristics are used for classifying the soils of the Sarawak at the Group level. The diagnostic horizons are generally subsurface horizons underlying an epipedon or a leaf litter or at the surface of a partially truncated soil. They are mostly B horizons but may include part of the A horizons
