Soil samples are collected from the Piatra Craiului National Park. Park has a surface of 14,800 ha. This type of soil has the following diagnostic horizons: Ao, Bv, C are analyzed following parameters: pH, organic C, total N, SH, SB, The soil is strongly acid reaction (pH = 3.45-4.57). High organic matter and total nitogen in the upper horizont. Key words: forest soil, organic carbon, nitrogen. INTRODUCTION National Park extends over the counties of Brasov, Arges, including areas belonging localities Bran, Moeciu (villages Magura and Pestera), Bran, Rucar and Dambovicioara. The total area of the Piatra Craiului National Park is 14,800 ha of which 7806 ha in Brasov and 6994 in Arges (Dumitru and Toader, 2004). Figure 1. Map of Piatra Craiului National Park Total carbon in forest ecosystems is given of existing content in biomass, dead wood, in the litter and soil. The highest amounts are found in living biomass and soil. Evolution of forest carbon stock in soil is influenced by natural factors and anthropogenic. Globally, forests store large amounts of carbon sequestered from the atmosphere and retained in living and dead biomass and soil. 34 MATERIALS AND METHODS The research was performed in the Piatra Craiului National Park and were followed some chemical indicators. The soils pH was electri-chimically determinat in water, the reading being fulfilled wich Thermo Orion 3 pH-meter. The organic carbon was determined thoug the dry ignition method by using the Leco Tru Spect CN automatic analyser. The total nitrogen from de soil was established through the humid mineralization method and titrimetrical dosage-Kjeldahl method with the Gerhard mineralizor and still. (ICP forests, 2010) The exchange acidity the extract of potssium acetate. The basic cations (K + , Na + , Mg ++ , Ca ++ ) were determined through the repeated blenders wiht ammonium acetat, total cationic exchange capacity (T), by summing SB + Ac, the saturation degree of base (V%), the formula V% = SB/T*100. RESULTS AND DISCUSSIONS The resultas regard distribution of values for physico-chemical indicators of surfaces with dystric cambisols from the Piatra Craiului National Park.
