1. PEDOGENESIS ON COASTAL TABLELANDS AREA WITH LOW RANGE ALTIMETRY IN PARAÍBA STATE
RESUMO Pequenas variações de relevo influenciam na drenagem e no escoamento superficial, contribuindo para a formação de horizontes superficiais arenosos e subsuperficiais endurecidos (fragipãs e, ou, duripãs) em solos dos Tabuleiros Costeiros. Este trabalho investigou a pedogênese em área de Tabuleiros Costeiros com baixa amplitude altimétrica no E

2. Multivariate Analysis and Machine Learning in Properties of Ultisols (Argissolos) of Brazilian Amazon
ABSTRACT: Ultisols are the most common soil order in the Brazilian Amazon. The Legal Amazon (LA) has an area of 5 × 106 km2, with few accessible areas, which restricts studies of soils at a detailed level. The pedological properties can be estimated more efficiently using statistical procedures and machine learning techniques, tools which are capable of rec

3. Cemented Horizons and Hardpans in the Coastal Tablelands of Northeastern Brazil
ABSTRACT Horizons with varying degrees of cementation are a common feature of the soils from the coastal tablelands of Northeastern Brazil. In most cases, these horizons are represented by the following subsurface horizons: fragipan, duripan, ortstein, and placic. The aims of this study were to analyze differences regarding the development and the degree of

4. Carbon pool ratios as scientific support to field morphology in the differentiation of dark subsurface soil horizons
In soil surveys, it is usual to find profiles with an uncommon disposition of horizons. Dark horizons in depth might be either the consequence of erosion and redeposition of soil materials from upslope or an indication of the podzolization process, which forms a spodic horizon. Few laboratory analyses are known to characterize dark subsurface horizons which

5. Solos de tres areas de restinga. II. Dinamica de substancias humicas, ferro e aluminio.
Substancias humicas foram fracionadas e feitas extracoes de Fe e Al com ditionito (Fe d e Al d), oxalato (Fe o e Al o) e pirofosfato de sodio (Fe p e Al p) com intuito de estudar os aspectos de formacao de solos de tres areas de restinga no litoral fluminense sob diferentes coberturas vegetais. No ambiente de forte hidromorfismo da Lagoa de Robalo, acidos hu

6. As abordagens sistêmica e do equilíbrio dinâmico na análise da fragilidade ambiental do litoral do Estado de São Paulo: contribuição à geomorfologia das planícies costeiras / Systemic approaches and the dynamic equilibrium in the analysis of environmental fragility of the coast of the state of S Paulo: contribution of geomorphology of coastal plains
The principal aim of this research, based on the Systems Approach and on the Dynamic Equilibrium, is to evaluate geological and geomorphologic different configurations and environmental fragility on the several geomorphologic topographic features in the coastal plains of Fortaleza bay in Ubatuba, located in the north coast of São Paulo and Peruíbe-Itanhaé
