    Water-Extractable Organic Matter of the Soils with Different Degrees of Erosion and Sedimentation in a Small Catchment in the Central Forest-Steppe of the Central Russian Upland: Soil Sediments on the Dry Valley Bottom

    The composition of the water-extractable organic matter (WEOM) of sedimented soils, namely, dark-humus water-accumulative stratozems (Fluvic Chernic Phaeozems (Loamic, Pachic)) in the nonplowed bottom of a dry...

    Water-Extractable Organic Matter of Soils with Different Degrees of Erosion-Induced Degradation and Sedimentation in a Small Catchment in the Central Forest-Steppe Part of the Central Russian Upland: Tilled Soils

    Dissolved organic matter is the most mobile part of soil organic matter; however, its change and transformation occurring during soil erosion are insufficiently studied. We assess the optical properties of wat...

    Heterogeneity of Organic Matter of Aggregates of Protocalcic Chernozems

    Layers were step-by-step removed from macroaggregates (2–1 mm in diameter) of Protocalcic Chernozems via successive abrasion in a revolving rotator during 5, 10, 15, and 39 h. During processing, the aggregates...
