Within the administrative area of Dărmăneşti city there is a great variety of soils which supports vegetation including those of forests’. The variety of soils is due to relief, rocks, phreatic waters, vegetation, climate, hydrographical network, altitude, different orientation and exposition of valley slopes, the meadows and terraces, deforestation and forest existence of farming that accelerated erosion and changed the balance of organic matter and soil nutrients.
Generally, the soils from Dărmăneşti basin favour forest vegetation, in the central and south-eastern area with fragmented and low energy relief, which under proper fertilization crop lands are favoured. In the mountain depression brown forest soils are found, as well as brown acid soils, mountain brown soils and meadow brown soils. Soils occupying over 95% of the basin are the brown forest with varying degrees of podzolization. Meadows have alluvial soils of 20-35 cm thick, brown, dark yellow with a humus content of 1.3 to 7%. They have a light texture and are poor in nutritive substances covered by low quality pastures. On the un-flooded terraces, at 2-4 m altitude compared to the thalweg of Trotuş River, we can find the alluvial brown soil, which has a higher fertility level and moisture, being suitable for field crops. These soils serve for agriculture, vegetable crops, forages and pastures. Carbonatic alluvial soils are more fertile.
On Uz River and its tributaries valleys, under beech, fir and spruce forests, acid forest soils were formed: brown soils and podzolic brown forest soils. Podzolic forest soils occupy the central part of the towns and are met on flat and low sloping relief, and on all terraces and all inter-rivers.
