TITLE:

SUMMARY:

The fluvial-marine plains are environments closely related to continental and oceanic factors, since they are located in coastal areas and form high salinity soils. In the northern area of Rio Grande do Norte (RN), due to the geomorphological and climatic conditions, these plains are characterized as hypersaline environments and allow the development of specific activities that benefit or adapt to saline stress. Considering the limitations of saline soils in terms of use and cover, the pedogeochemical conditions of the fluvial-marine plain of the Apodi-Mossoró River were investigated, in order to verify their potential for the development of anthropogenic activities. For this, soil samples were collected with varying depths in different hypersaline environments. Laboratory analyzes indicated a soil with high concentrations of Na⁺, Ca²⁺ and Mg²⁺, presenting a sodium classification, salic character and moderately alkaline condition; these characteristics are a reflection of the influence of the semi-arid climate and progressive evaporation of sea water in the supratidal area, favoring the precipitation of salts along the estuary. The granulometry of the sediments, in turn, indicated the predominance of finer particles such as silt and clay in the textural composition of the soil.
