This study explores the functional potential of hydric soils located in the lowlands and wetlands of Delta State, Southern Nigeria. Often dismissed due to seasonal inundation and persistent saturation, hydric soils develop under anaerobic conditions that limit oxygen availability. Despite these constraints, such soils exhibit significant levels of organic matter and fertility that could be optimized for agricultural use, especially within the context of sustainable land management and environmental conservation. A field survey method was employed, involving the collection of ninety (90) soil samples—thirty (30) each from three stratified zones representing lowland and wetland environments across the Delta State. These samples were subjected to detailed laboratory analyses to determine their physicochemical properties. The resulting data were statistically analyzed to identify patterns in soil fertility, nutrient content, and suitability for cultivation. Results indicated a consistent presence of organic matter and similar nutrient availability across the studied landscapes, comparable to those in forest and fallow lands. This similarity supports the argument that lowland and wetland soils, though often underutilized, can serve as viable alternatives to conventional arable lands. Their utilization may reduce reliance on rainforest areas and promote ecological balance. In conclusion, the study underscores the importance of re-evaluating hydric soils for agricultural purposes. Leveraging their potential could support precision agriculture, reduce soil degradation, and contribute to achieving Sustainable Development Goals (SDGs) 12 and 13 related to responsible consumption and climate action. Thus, hydric soils represent both a challenge and an opportunity in modern land use planning.
