Conteúdo: | Northeastern Brazil possesses a wide variety of environments, soils, substrates, and climates, although semi-arid conditions prevail in the core area of this biome, under thorny shrubby and succulent Caatinga vegetation. There, soils vary from shallow to deeply weathered, but in general, there is a predominance of a lower weathering degree and high fertility soils, compared with all other Brazilian regions. The high pedodiversity of this semi-arid domain is a consequence of a wide range of parent materials, especially on crystalline basement rocks (gneiss, granitoids, mica-schists). The most typical soils are Luvissolos (Luvisols), Planossolos (Planosols and Solonetz), and Neossolos Litólicos or Regolíticos (Leptosols and Regosols). On highland sedimentary basins, soils are pre-weathered and with very low fertility, predominantly Latossolos (Ferralsols) and Neossolos Quartzarênicos (Arenosols), where sandstone predominate. However, large areas of limestone also occur, giving way to soils with higher fertility, influenced by carbonates. The largest areas of these limestone soils comprise Cambissolos (Cambisols) with a small proportion of Vertissolos (Vertisols), and minor, restricted areas with Chernossolos (Chernozems). In the transitional zones with wetter areas, intermediary soils have low fertility, normally deeper, weathered, and degraded, notably Latossolos (Ferralsols), Argissolos (Acrisols and Lixisols), and Neossolos Quartzarênicos (Arenosols).
