ROLE OF NON-PRODUCTIONAL FUNCTIONS OF GRASSLAND IN SOIL PROTECTION AND ENVIRONMENT
There is more than 800 000 ha of grassland in Slovakia. Besides its primary productional-function, grassland has also non-productional functions, which are performed mainly by its root biomass. The amount of roots in grassland soils is several times higher in comparison with annual crops on arable land. In grassland soil there is about 7.3 – 8.3 t DM (dry matter).ha-1 of root biomass depending on grassland type, its management and mineral nutrition.
