Forests occupy approximately 27% of Romania’s total surface. Forest soils from Ialomița County were characterized based on a large number of soil analysis obtained during the last 26 years (namely 127 soil profiles and 335 pedogenetic horizons). These soils are characteristic to the field area from the silvosteppe areal and have developed under a humid regime (phaeozem, chernozem, preluvisol, luvisol, fluvisol). Chernozem and cambic phaeozem have a weak alkaline reaction and a B cambic horizon (Bv) resulted from the clay’s concentration, while carbonates are concentrated in depth. Fluvisols have a large development in the Danube’s meadow, especially in its affluent, namely Ialomiţa River’s meadow. The parental material is represented by sands, clay sands and slime. Furthermore, organic matter in humification progress is also present. Luvisols and preluvisols are moderately acid soils in the Ao and Bt horizons, mesobasic in Ao and Bt and with a high cationic exchange capacity. They are also moderately humiferous, well supplied with nitrogen and with a good cationic exchange capacity.
