Abstract:
Forest soils represent an important resource for Covasna County, characterized by a large surface of both private and
national forests. The forest soils (that differ from agricultural soils) were analysed based on the following chemical
characteristics: soil’s solution reaction, base saturation degree, humus and total nitrogen content and the total cationic
exchange capacity. A total number of 15 soil types were analysed in Covasna County. The most widespread ones are
eutric cambisol and dystric cambisol, which cover together 77% of the surface. At the same time, the most acid soils are
entic podzols, while the most alkaline are rendzic leptosols. The majority of soils are mezobazic, moderately or
intensely humiferous, well and very well supplied with nitrogen. Entic podzol has a very large cationic exchange
capacity, while all other soils have high capacities. The chemical characteristics of forests soils from Covasna County
are favourable to forest vegetation, a fact that can be observed by the stands’ productivity.
