Andosols of Georgia
Tóm tắt
Andosols formed on andesite-basalts, andesite, diabase, and dolerite in the central part of the Adzhar-Trialet Ridge are studied. Their morphological features and some chemical properties are characterized. The soils are diagnosed according to the World Reference Base for Soil Resources (WRB). The soil bulk density, the contents of oxalate-soluble R2O3, adsorbed phosphates, and organic carbon are determined. It is shown that vitric and andic diagnostic features predominate in the investigated soils. According to the adopted classification, these soils are classified as mountain meadow soils. Their morphological features and chemical characteristics correspond to those of Andosols, one of the soil groups in the WRB. It can be expected that these soils are developed in some other regions of volcanic activity in Georgia.
