Chages in physical and chemical soil characteristics as a result of subsurface tile drainage

Popis výsledku v původním jazyce

This project defined changes in soil properties after construction of subsurface tile drainage. We compared the physical and chemical properties of soil samples taken before construction of drainage and new soil samples taken from identical sites at present. The research was made for Stagnic Cambisols (Dystric) and Haplic Stagnosols. The pH value and saturation of the topsoil sorption complex of both soil types statistically increased and simultaneously the cation exchange capacity (CEC) decreased. In the topsoil of Stagnosols, the effective cation exchange capacity and porosity also decreased, and at the same time the particle density and bulk density increased. Soil organic matter and minimum air capacity increased in the topsoil of Cambisols. Porosity and minimum air capacity increased in both soils in the subsoil. In the Cambisol subsoil, the CEC and bulk density decreased. We can assume that after drainage Stagnosols are susceptible to soil compaction, especially in topsoil.
