Abstract :The aim of this study was to determine the chemical properties of peat soil depending on changes in land-use. The Terric Histosol insert ignore into journalissuearticles values(HSs); was investigated in this research, and the treatments of former different land-use in Radviliškis site. Chemical analyses were carried out at the Chemical Research Laboratory of LRCAF. After 12 years since the end of field experiment the differences in soil chemical composition remained still between treatments of differently used peat soil. Due to mineralization, the content of soil organic matter insert ignore into journalissuearticles values(SOM); and SOC respectively decreased, the largest amounts of SOC are stored in the upper soil layer of perennial grasses fertilized with NPK insert ignore into journalissuearticles values(NPK);, there was the highest yield of biomass; and accordingly, the lowest content of SOC – in soil of un-used peat insert ignore into journalissuearticles values(UU);. The distribution of total N and P in profile of Terric Histosol is directly related to the vertical gradient of mineralization intensity; higher amounts of N and P have been accumulated where mineralization was more intense. The distribution of total K is related to land-use of Terric Histosol , whereas the biggest quantity of total K was established in arable land which has been fertilized with mineral fertilisers.
