DESCRIBING AN OWN CALCULATION PROGRAM FOR THE ORGANIC CARBON FROM SOILS (STOCS) AND ITS MAIN APPLICATIONS PUBLISHED

L. C. DINCĂ
Abstract. StOCS or the program for calculating the organic carbon from soils has more than one phase. In a first stage, it calculates the quantity for organic C (in g/kg) on each type of soil, then on the standard depths of 0-10 cm, 11-20 cm, 21-40 cm and 41-100 cm. It then calculates the total stock of organic C, differentiated on soil types. The program is extremely useful for the analysis of a large number of analytical determinations. This paper presents two applications of this program: the analysis in time of the variation of organic C stock from the same administrative area (3 forest districts at intervals of 10 years) and the analysis of the organic C stock variation in time at the level of the entire country (30 forest districts for each year of the 2000-2009 period). The program can be used for the calculation of national or regional organic carbon stocks that are required for the United Nations Convention for Climatic Changes reports or for the Kyoto Protocol reports or for the analysis of data obtained at soil monitoring inventories.
Key words: organic carbon, forest soils, bulk density, forest management plans, humus
