Soil absorbing complex properties of Russian boreal soils and its dependence on the spatial scale of study area

Regional differences of CEC and exchange acidity of boreal soils with a textural differentiation were studied and relationships CEC vs silt and CEC vs organic matter were described on 4 spatial levels: ‘continent’ (the area is about 5 millions km2 ), a region (200 thousand km2 – 1 million km2), a co...

Zusammenfassung:Regional differences of CEC and exchange acidity of boreal soils with a textural differentiation were studied and relationships CEC vs silt and CEC vs organic matter were described on 4 spatial levels: ‘continent’ (the area is about 5 millions km2 ), a region (200 thousand km2 – 1 million km2), a county (="oblast" in Russian, 40–370 thousand km2), a field (0.06–2 km2). Characteristic differences were observed for different spatial levels and geographical areas.
