Morphological,Chemical, Mineralogical Properties And Soil Classificationsin Some Toposequens Of Mamuju District West Sulawesi
This study determinesthe morphological,chemical,mineralogicalproperties, and soil classification in several toposequences in Mamuju District,West Sulawesi. The research method used is a descriptive exploratory method supported by laboratory analysis data. The results showed yellow and brown soil color, clay texture, subangular structure, slightly sticky consistency, and graduallydiffuse horizon boundaries. The Cation Exchange Capacity ranges from Medium to high, very low to low base saturation, and low carbon percentage. The topsoiland subsoilmineral content aredominated by clay mineralsand other minerals such as biotite, opaque, muscovite, and feldspar. Soil classificationis classified into the Udepts Suborder, Great Group Dystrudepts,and TypicDystrudepts Subgroup (Profiles 1 and 3). In contrast,Profile 2 is classified into Suborder Humult and Great group Haplohumult and Subgroup Typic Haplohumult.
