For the Year 2023 Soil of Estonia by the Estonian Soil
Science Society was elected the Podzolic or podzolized soil, which is
known by the World Reference Base for Soil Resources (WRB) as Umbric
Podzol. In introduction of actual review the Podzolic soils’ morphology
and their subdivision principles (by moisture conditions and profile
development) are analysed. By the Estonia Soil Classification totally
seven species of podzolized automorphic soils have been separated, from
which each species have an original code used in the soil mapping. By
mean of schematic map is characterized the distribution of these soils in
Estonia, but by mean of normally developed soils’ matrix the co-evolution
with other soil species. Podzolic soils are formed totally 5.0% from the
total Estonian soil cover, but 4.3% from the forest and 5.2% from the
arable land. Special attention was payed to humus status of these soils,
characterizing among others humus cover (or humipedons) fabric and
essential properties separately on forest and arable lands. Beside of
depending on soil texture, moisture conditions and land use, soil
quantitative characteristics (given by soil species or by soil groups), as
well the results of comparative analysis and using peculiarities of Podzolic
soils in agricultural practice have been explained. At end of the review the
possibilities for characterizing Podzolic soils’ species and varieties
peculiarities by mean of principal and supplemental qualifiers WRB is
explained.
