The primary objective of this research is to evaluate the possibilities of maintaining the optimal natural potential of soils within a sustainable land use framework. This involves assessing the land’s capacity to support various agricultural activities without compromising natural resources while ensuring long-term soil fertility. In the studied area, the floodplain of Roseți Commune, Călărași County, four main soil types were identified: Alluvisols, Gleysols, Psamosols and Anthrosols. These soils reflect ecological diversity and pedological conditions specific to floodplain areas, exhibiting a slightly alkaline pH (7.2-7.6). Alluvisols are fertile soils formed through alluvial deposits and have a moderate humus content (3.92%). In contrast, Gleysols are characterized by poor drainage and intense gleying processes due to high moisture excess, with a low humus content (1.68%). Psamosols, with a high sand content, have a reduced water retention capacity and a moderate humus supply (2.56%), whereas Anthrosols are soils modified by human activity. The identified soils are well supplied with phosphorus (65-71 ppm) and potassium (160-360 ppm), ensuring the agricultural and ecological potential of the region.
