“…Profiles P1, P2, and P3 were classified as Umbric Ferralsols according to the World Reference Base for Soil Resources (IUSS Working Group WRB, 2014) and Latossolo Vermelho‐Amarelo with the presence of a humic horizon according to the Brazilian System of Soil Classification (SiBCS) (Santos et al, 2018).…”

“…The morphological, physical, and chemical properties of Ferralsols indicate a high degree of weathering due to the expressive action of the pedogenic process of ferralitization (Buol et al, 2003; IUSS Working Group WRB, 2014; Kämpf & Curi, 2012). In Brazil, Ferralsols correspond to Latossolos (Santos et al, 2018), which occupy almost 32% of the country's territory (Santos et al, 2011).…”

The formation of strongly weathered soils of the tropics (Ferralsols) with high carbon stocks (thick A-horizon/umbric horizon) is still not understood. In order to contribute to the understanding of the formation of Umbric Ferralsols, we studied these soils in the highlands of Rio de Janeiro state (Brazil) from various perspectives. We analysed soil morphology, micromorphology, physical and chemical soil attributes, soil phytolith assemblages, and δ 13 C isotopic composition in a multi-proxy study. The profiles presented ferralic horizons with SiO 2 /Al 2 O 3 ratio (k i index) < 1.0, low silt/clay ratio values, predominance of kaolinite and presence of gibbsite, and low cation exchange capacity. These characteristics indicate a high degree of weathering and ferralitization. The isotopic and phytolithic variations indicate climatic modifications during the Late Holocene (approximately 2300 years ago), with a predominance of mixed vegetation composed of plants of the C3 and C4 photosynthetic cycles. This condition favoured the accumulation of organic matter in the Umbric Ferralsols. The accumulation of organic matter in subsurface B horizons occurred under drier past climatic conditions in a savanna environment, which may have favoured the occurrence of fires, thereby explaining the charcoal fragments identified in the micromorphological analyses. In contrast, the development of the umbric horizon in the profiles was favoured under wetter environmental conditions than the present environmental conditions, and favoured the development of vegetation and intense accumulation of organic material on the surface and at depths close to 100 cm. The pedogenesis of umbric horizons in Ferralsols reinforces the importance of bioturbation in the incorporation of organic matter, intensifying the humification and resulting in a strong darkening of the soil (melanization).

“…Apresentam baixa fertilidade natural e piçarra a partir de 15 a 20 cm de profundidade de solo, características que limitam o desenvolvimento do sistema radicular das plantas e, consequentemente, as atividades agrícolas. A descrição morfológica do solo revelou que os solos desta classe correspondem às classes Gleissolos Melânicos e Plintossolos Argilúvicos (SANTOS et al, 2018), e aos Gleissolos Háplicos, de acordo com o mapa pedológico realizado (SÃO PAULO, 2017).…”

Esta pesquisa diagnosticou o conhecimento empírico dos agricultores do município de Campina do Monte Alegre - SP sobre a classificação e uso agrícola dos solos e o correlacionou ao Sistema Brasileiro de Classificação de Solos (SiBCS) e à classificação da capacidade de uso das terras. A pesquisa etnopedológica englobou 20 áreas agrícolas e 17 agricultores foram entrevistados. A metodologia consistiu nas seguintes etapas: 1) elaboração do roteiro semiestruturado e realização das entrevistas; 2) amostragem e descrição morfológica dos solos; 3) sistematização e análise de conteúdo das entrevistas, com auxílio do software ATLAS.ti e 4) elaboração do mapa pedológico. Os principais atributos etnopedológicos utilizados pelos agricultores foram: cor, textura, consistência, fertilidade, acidez, teor de matéria orgânica, pedregosidade e plantas indicadoras. As classes etnopedológicas identificadas foram: “Terra Vermelha ou de Campo” (Latossolos Vermelhos, Argissolos Vermelhos e Argissolos Vermelho-Amarelos); “Terra Roxa” (Nitossolos Vermelhos e Latossolos Vermelhos); “Terra Branca” (Plintossolos Argilúvicos; Gleissolos Melânicos e Gleissolos Háplicos) e “Terra de Areia” (Argissolos Bruno-Acinzentados e Argissolos Vermelho-Amarelos). As classes etnopedológicas “Terra Vermelha ou de Campo” e “Terra Roxa” predominaram nas áreas agrícolas visitadas e, conforme o sistema de capacidade de uso das terras, foram classificadas como IIe,s e IIIe,s.
