ABSTRACT Quilombolas are Afro-brazilian rural peasants who descended from escaped slaves who tried to carve out territories of autonomy (called Quilombos) by collective organization and resistance. Despite many anthropological and ethnopedological studies, little research has been carried out to identify the agricultural practices and the knowledge of people who live in the Quilombos (Quilombolas). Peasant communities who live from land resources have wide empirical knowledge related to local soils and landscapes. In this respect, ethnopedology focuses on their relationship with local practices, needs, and values. We carried out an ethnopedological evaluation of the soils, landscape and land suitability of the Malhada Grande Quilombola Territory, aiming to... |

Considerando a expressividade de Cambissolos (rasos, adensados e siltosos) e Latossolos argilosos e muito argilosos desenvolvidos de rochas pelíticas do Grupo Bambuí, bem como os poucos estudos relacionados à gênese e potencialidade agrícola desses solos, selecionaram-se duas áreas no município de Curvelo-MG, cujo objetivo foi estudar suas características físicas, químicas e mineralógicas. Para isso, foram descritos e coletados perfis de Cambissolos Háplicos (CX), Latossolos Vermelho-Amarelos (LVA) e Latossolos Vermelhos (LV), sendo a TFSA submetida às análises físicas e químicas de rotina, digestão total e sulfúrica, além das análises mineralógicas. Os difratogramas de raios X (DRX) e o índice de intemperismo (Ki) dos CX indicaram menor grau de pedogênese... |

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) in the Triângulo Mineiro region, Brazil, describing the soil-water-landscape relationships to understand land use and water resources. To this end, we applied physical, chemical, micromorphological, and morphometric methods. When dry, compaction was observed in well-structured Ferralsols (Latossolos) with medium texture under intensive agriculture, reducing the water recharge capacity. The soil carbon... |

ABSTRACT: A set of attributes endows the soils with distinctive characteristics and astute understanding is required in order to formulate suitable strategies for soil management. The aim of this study was to physically, chemically and mineralogically characterize samples of the main soil classes in Minas Gerais, Brazil, determine the point of zero salt effect (PZSE) and the point of zero charge (PZC), and ascertain the correlation between these factors and soil attributes. The soils evaluated presented different textural classes ranging from loamy sand (Entisol) to very clayey (some Oxisols and Ultisols). The soils differed substantially in terms of fertility, presenting a range from dystrophic (low fertility, base saturation < 50 %) to eutrophic... |
