ANDISOLS AS REPRESENTATIVES OF ABNORMAL SOILS

The input of material at the surface of soils results in the developme nt of abnormal (according to V.V. Dokuchaev) soils. The slow rate of t his process favors for intensive humus accumulation in added material and for formation of deep-humus soils. Catastrophic burying of soils c auses the formation of humusless layers within a soil profile. Reworki ng of geological deposits by a pedogenic process can be defined as ped olysis, i.e., the impact of developed soil on geological substratum.
