Research Data for the manuscript ”Rainwater Chemistry Shapes Soil Stability and Erosion Processes in Chernozem”

Table 1 Concentration (mg L-1) of total calcium ions (soluble and suspended) leached by rainwater and retained over time. Table 2 Concentrations of ∑(Ca2++Mg2+), total calcium (soluble and suspended), and organic matter (as CODCr) leached by rainwater and retained over time. This dataset contains the experimental measurements used in the study “Influence of Rainwater Chemistry on Soil Erosion and Stability in Typical Chernozem Soils.” It includes raw and processed data generated from controlled laboratory simulations examining how acidic, moderate, and ammonium-rich model rainwater influence the dissolution, hydration, and structural stability of calcareous Chernozem soils. This dataset contains the measurements used in the study on how different types of rainwater (acidic, moderate, ammoniacal) affect dissolution, hydration, and structural stability of calcareous Chernozem soils. It includes: (1) chemical composition of model rainwaters; (2) Ca²⁺ and Mg²⁺ dissolution data from three Chernozem soil types; (3) suspension stability, settling behavior, and COD measurements; and (4) aggregate stability data from controlled freeze–thaw experiments.
