(Calcaric), Haplic Cambisol; ST: Rendollic Eutrudepts) Order 4. Rusty soils (; WRB: Arenosols; ST: Entisols - Psamments) In this order are situated sandy soils with rusty sideric or rubic horison of weathering or iron accumulating. Morphologicaly they are similar to brown forest soil but soil forming process is slightly different, their parent material is always a sand and they are much less fertile. - Type 4.1 "Rusty soils" (; WRB: Brunic or Albie Brunic Arenosol (Dystric), Brunic Endogleyic Arenosol; ST: Typic or Spodic or Oxiaqic Udipsamments) - Type 4.2 "Ochre soils" (; WRB: Rubic Arenosol; ST: Typic Udipsamments) Order 5. Brown forest podzolic soils (Soil lessivé) (; WRB: Luvisols, Albeluvisols; ST: Alfisols - Aqualfs, Udalfs) This order covers soils where clay leaching by snowmelt or rainy water leeds to develop eluvial horizon (luvic) from which clay has been leached and illuvial horizons (argic) in which clay has been deposited. Parent material may be from loamy sand to clay. - Type 5.1 "Brown forest podzolic soils" (; WRB: Albic or Haplic or Stanic or Gleyic or Lamelic or Vertic Luvisol; ST: Typic or Arenic or Aquic or Oxyaquic or Mollic or Psammentic or Lamelic or Glossic or Vertic Hapludalfs) - Type 5.2 "Streak brown forest podzolic soils" (; WRB: Haplic or Stagnic or Gleyic or Cambic Albeluvisol; ST: Typic or Arenic or Aquic or Oxyaquic or Haplic or Glossaqiuc or Vertic Glossudalfs) - Type 5.3 "Wet brown forest podzolic soils" (; WRB: Gleyic Luvisol; ST: Typic or Umbric or Mollic Endoaqualfs, Typic Argialbolls) Order 6. Podzol soils (; WRB: Podzols; ST: Spodosols) That order groups all soils where main soil developing process was podzolisation, spodic horizon is diagnostic for that group. - Type 6.1 "Podzolic soils" (; WRB: Haplic or Orsteinic or Gleyic Podzol; ST: Typic or Oxyaquic or Aquic Haplorthods, Spodic Udipsamments, Humaqueptic Psammaquents, Typic Duraquods, Typic or Umbric or Histic Endoaquods) - Type 6.2 "Podzols" (; WRB: Albic Podzol, Albic Orstenic or Stagnic or Gleyic Podzol; ST: Typic Haplohumods, Spdic Udipsamments, Typic or Oxyaquic Haplorthods, Humaqueptic Psammaquents, Typic Duraquods, Typic Epiaquods, Typic Endoaquods) Order 7. Chernozemic soils (; WRB: Chernozems, Phaeozems; ST: Mollisols - Aquolls, Udolls) This order includes all soils with deep humus horizon, accumulated in both: wet or dry conditions. They are usually fertile, there is predominance of humin acids and presence of organic-mineral connections. - Type 7.1 "Chernozems" (; WRB: Calcic or Haplic or Luvic or
