The Coastal Tablelands (CT) or Tabuleiros Costeiros are formed by the extensive coastal sedimentary strip, along a north-south direction, with a predominant width between 10 and 160 km, ranging from Rio de Janeiro to Amapá State, and formerly covered by Rainforest, with many contrasting peculiarities of soils with adjacent soil regions. Landforms are usually low plateaus (20-220 m.), developed on subhorizontal Cenozoic continental sediments of the Barreiras Group, with varying texture. Explored since the early days of Brazilian colonization, the Coastal Tablelands lost virtually all of its original vegetation cover, the Atlantic Forest, after 500 years of occupation of Brazilian coastal areas. The climate and agricultural conditions are varied, and soils, although chemically poor, are favorable to the agricultural operations, especially for perennial crops. Pastures, sugarcane, and eucalyptus are prominent land use in the CT, especially in the Southeastern and Northeastern regions. Despite the unequivocal suitability for perennial crops, some characteristics, however, constitute natural obstacles that limit generalized agricultural use: the low natural fertility of soils, subsurface cohesion or densification, and local climatic conditions. Due to the intense pre-weathering and chemical leaching, and the consequent lack of weatherable primary minerals in all CT soils, most nutrients are originally associated with the biomass and are easily lost. The removal of the native vegetation, especially the original forest, besides the routine practice of burning, resulted in widespread soil degradation. In the CT region, areas with >3% slope show strong sheet erosion, especially under high rainfall. On the other hand, the occurrence of the subsurface densified layer hinders surface leaching, and contributes to the increasing surface erosion, limiting root penetration and water drainage in the soil. This strong densification, generally between 30 and 70 cm depths, requires management practices such as subsoiling in common citrus, papaya and eucalyptus crops. This technique improves the physical conditions and the nutrients' cycling, resulting in good yields. Also, the adoption of management practices that maintain soil moisture is efficient in reducing the effect of natural soil cohesion. The CT soils have very low amounts of silt and are therefore not prone to crusting. In CT dominated by cohesive Argissolo Amarelo (Acrisols) and Latossolo Amarelo (Ferralsols), agricultural use with perennial crops attained success, even where densification is intense, with soil bulk density >1.5 g cm-3, but subsoiling is required. Other soils of reduced geographic expression in the Coastal Tablelands present other limitations that seriously undermine agricultural use, such as Argissolos Acinzentados (Acrisols), Espodossolos (Podzols), Neossolos Quartzarênicos (Arenosols), Plintossolos (Plinthosols). Espodossolos (Podzols) under open, grassy to shrubby Mussununga vegetation are very acidic and sandy and may present drainage constraints imposed by the presence of fragipan or "ortstein".
