1. Predicting the potential distribution of aquatic herbaceous plants in oligotrophic Central Amazonian wetland ecosystems
ABSTRACT Aquatic herbaceous plants are especially suitable for mapping environmental variability in wetlands, as they respond quickly to environmental gradients and are good indicators of habitat preference. We describe the composition of herbaceous species in two oligotrophic wetland ecosystems, floodplains along black-water rivers (igapó) and wetlands upo

2. Digital Soil Mapping Using Machine Learning Algorithms in a Tropical Mountainous Area
ABSTRACT: Increasingly, applications of machine learning techniques for digital soil mapping (DSM) are being used for different soil mapping purposes. Considering the variety of models available, it is important to know their performance in relation to soil data and environmental variables involved in soil mapping. This paper investigated the performance of

3. Visual Evaluation of the Soil Structure under Different Management Systems in Lowlands in Southern Brazil
ABSTRACT The “Visual Evaluation of Soil Structure” (VESS) is a method used primarily to evaluate the soil structural quality of Oxisols in Brazil and secondly for more specific research, consultancy, and teaching purposes. Since the methodology was never applied and compared with laboratory evaluations of physical properties of hydromorphic soils of the

4. Hydropedology of a High Tableland with Cerrado, Brazilian Central Plateau: the Frutal Catchment Case Study
ABSTRACT: Currently, the Brazilian savanna (Cerrado) represents the main agricultural area of the country, comprising a great variety of landscapes and soils, geological formations and vegetation patterns, as well as the major watershed. We studied the hydropedology and morphometry of a representative catchment (Frutal river), on a high tableland (Chapada) i

5. Organic Matter Stocks and the Interactions of Humic Substances with Metals in Araucaria Moist Forest Soil with Humic and Histic Horizons
ABSTRACT Soils with humic and histic horizons in tropical and subtropical ecosystems play an important role in determining the atmospheric C stock and its stabilization, climate regulation, water holding capacity, and environmental filtering, due to the different functions of soil organic matter (SOM). However, the processes and mechanisms that regulate SOM

6. Soil-vegetation relationships and community structure in a "terra-firme"-white-sand vegetation gradient in Viruá National Park, northern Amazon, Brazil
ABSTRACT Viruá National Park encompasses a vast and complex system of hydromorphic sandy soils covered largely by the white sand vegetation ("Campinarana") ecosystem. The purpose of this study was to investigate a vegetation gradient of "terra-firme"-white sand vegetation at the Viruá National Park. Nine plots representing three physiognomic units were ins

7. Characteristics of Soils in Highland Wetlands as a Subsidy to Identifying and Setting their Limits
ABSTRACT Palustrine areas and wetlands in particular are fragile ecosystems, with high biodiversity and high ecological productivity, and they provide benefits to society. The aim of this study was to describe and classify the main soils occurring in the wetlands of the Southern Plateau of Santa Catarina, and propose criteria for identification of hydromorph

8. Relações pedologia-geomorfologia-sedimentologia no Pantanal Norte / Relationships pedology-geomorphology-sedimentology in the Pantanal North
As relações entre os solos, material de origem e feições geomórficas são importantes para a compreensão da distribuição dos solos na paisagem e o entendimento de sua variabilidade espacial, sobretudo em ambientes úmidos (wetlands) de natureza sedimentar complexa. Procurou-se descrever e caracterizar os ambientes deposicionais de uma área de estudo

9. Aptidão agrícola das terras da bacia hidrográfica do Ribeirão Taguatinga, Distrito Federal.
RESUMO: A área da bacia hidrográfica do Ribeirão Taguatinga (Área de Relevante Interesse Ecológico Juscelino Kubitschek - ARIE JK), no Distrito Federal, tem superfície de 77,50 km2. As principais classes de solos que ocorrem nessa área são: Latossolos, Argissolos, Cambissolos, Gleissolos, Plintossolos, Neossolos Fúvicos e Neossolos Quartzarênicos c

10. ESTUDO DE TRAFEGABILIDADE APLICADO A VEÍCULOS DE RODA EM TRANSPORTE E TRAÇÃO / TRAFFICABILITY STUDY APPLIED TO WHEELED VEHICLES IN TRANSPORT AND TRACTION
The ability of vehicles to traverse soft soils is an important aspect of their performance. The geological, climate and topography diversity originated, in Rio Grande do Sul, extensive areas of hydromorphic clay soils, as example, Planssoils and Gleissoils. When saturated of water, these soft soils present low loads support, difficult agricultural machinery

11. "Horizontes cimentados em Argissolos e Espodossolos dos tabuleiros costeiros e em Neossolos Regolíticos e Planossolos da depressão sertaneja no Nordeste do Brasil" / "Cemented Horizons in ultisol and spodosols from the coastal tablelands and in inceptisols and alfisols from the "sertaneja" depression of Northeast Brazil"
The present study was carried out in cemented horizons in Ultisols and Spodosols from the coastal tablelands, and in Inceptisols and Alfisols from the sertaneja depression of Northeast Brazil. The emphasis was concentrated on the cemented horizons developed in smooth depressions in the coastal tablelands. The main objective was to identify the cementing agen
