Gilgai microtopography of soil from carbonate rocks

Gilgai microtopography is a characteristic topography of soils that develops from
carbonate rocks influenced by smectite clay minerals. The process of forming a gilgai can inhibit
the development of plant growth and soil stability. Soil genesis is an interesting topic to study,
especially concerning how moving clay forms a gilgai microtopography. The objective was to
study forming a gilgai microtopography formed from the parent material of carbonate rock in
Mangarabombang District, Takalar Regency. The methods used are survey methods, analysis of
soil physical characteristics and soil chemistry, and soil mineral. The results showed an increase
in clayeyness at the top horizon in line with decreasing permeability on the top horizon and
inversely proportional to soil porosity. The cation exchange capacity is higher at the top horizon,
which indicates an increase in clay content. The mineral content of clay is nontronite as a member
of the smectite group. Nontronite mineral formation subsidized by calcium and magnesium
cations from carbonate rocks. This mineral absorbed more water and caused the saturation
conditions triggering lateral pressure and forming a gilgai micro-topography
