In the meridional agreste of Pernambuco, the Regolithic Neosoil are used in various agricultural activities, which includes the production of beans. The productive potential of these soils may be different between the municipalities of occurrence due to the physicalhydric behavior exhibited by these soils, or the occurrence of lamellae in some areas, which may contribute to greater production. The objective of this study was to investigate the morphological, chemical and hydro-physical characteristics of Regolithic Neosoil located in the meridional agreste of Pernambuco in order to understand the behavior of water in these soils. Morphological, physical, chemical, water, mineralogical and micromorphological attributes of three profiles, being P1 (Caetés), P2 (Paranatama) and P3 (São João) were analyzed. Lamellae were found in horizons C1 and C2 of P3, which may be related to an increase in water retention profile. The morphological and chemical characteristics showed no differences to justify a differential productive bean between profiles. The micromorphology and hydric study showed that P3 has greater capacity to retain water, better distribution of pore diameters, and has a porosity and packaging material that promotes increased water retention than P1 and P2, mainly in C2 horizons and C4. The characteristics of P3 make this profile presents a higher yield potential than the profiles P1 and P2.
