| Abstract: | Gravitation soil solutions were inve stigated by using flatlysimeters in a nudal beech forest (group of types of geo biocens Fageta paupera typica inferiora,type of geobiocen Carex pilosa nudum),located in the Ecological Experimental Station (E E S) Kremnicke vrchy mountains (Central Slovakia).Chemical properties of the perco lated soil solutions were sampled monthly below surface humus (A0-horizon) and the 10 cm and 25 cm thick mineral layers of andosolic cambisol.The soils were sampled monthy in A0 horizon, 10 cm and 25 cm depth,and their contents of four chemical elements Ca,Mg, K and Na,and pH and conductivity were analysed.The following amounts of the basi c cat ions have been accumulated in mineral soil layers during the year (the balance i s negatively influenced by freezing of A0 lysimeter in the winter):calcium 2. 6 kg Ca2+.hm-2 and 14.2 kg Ca2+.hm-2，magnesium 2.1 kg Mg2+.hm-2 and 1.1 kg Mg2+.hm-2,potassium 42.1 kg K+.hm-2 and 2.3 kg K+.hm-2,sodium 5.5 kg Na+.hm-2 and 2.0 kg Na+.hm-2. |
