Afforestation affects vertical distribution of basic soil characteristics and taxonomic status of sodic soils

Afforestation, settled before 60–90 years and adjacent solonetzic grasslands, representing the natural vegetation cover were compared in this study based on their basic soil characteristics (pH, CaCO3 content, organic carbon (SOC), exchangeable sodium percentage (ESP)) up to 2 m depth. The assumption was that plantings of arbour can change sodic soils not only superficial layers but even larger depths. Grasslands forest by standardised Afforested showed lower pH depth at 0–100 cm, slightly higher SOC content subsoil (20–100 cm). significantly different (higher) 50–100 cm afforested soils. Remarkable differences ESP values measured. Afforestation had almost every layer (0–20, 20–50, 150–200 cm) a significant value than grassland samples from same As is relevant classification purposes as well, leaching also taxonomic status with natric horizon, Sodic or Bathysodic qualifiers.
