Analysis of soil characteristics and classification from order to family category in Makale District

Makale, with hilly and mountainous areas in Tana Toraja Regency, provides high agricultural productivity so that soil as a medium for growing plants is one aspect that needs attention. Minerals influence the soil's physical and chemical properties because they are the main constituent of the soil, so that the characteristics and types of soil will vary. This study aimed to determine the type of soil based on toposequences and catena sequences from order to family category in Makale district, Tana Toraja regency, according to soil taxonomy in 2014. The method used was toposequences and catena sequences in one transect. Soil physical and chemical analysis including; soil color, texture, bulk density, C-organic, CEC, K, Na, Ca, and Mg. Analysis of soil minerals using the Fourier Transform InfraRed (FTIR) method. The results showed that the soil types found in the Makale district were Lithic Udorthents, Typic Udorthents, Typic Haplohumults, Oxic Dystrudepts, Typic Eutrudepts, and Dystric Eutrudepts. The dominant clay minerals are montmorillonite in profiles 1 and 2, kaolinite in profiles 3 and 5, chlorite and quartz in profiles 4 and 6.
