Calcareous soils | FAO SOILS PORTAL | Food and Agriculture ...Calcareous soils have often more than 15% CaCO 3 in the soil that may occur in various forms (powdery, nodules, crusts etc.). Soils with high CaCO 3 belong to the Calcisols and related calcic subgroups of other soils. They are relatively widespread in the drier areas of the earth.. The potential productivity of calcareous soils is high where adequate water and nutrients can be supplied.
Parametric studies of the formation of calcareous deposits ... · The calcareous deposits contain mostly CaCO[sub 3], but the initial deposits are predicted to contain more Mg(OH)[sub 2] than CaCO[sub 3].
