Resumo: | Soils with low levels of organic matter and high compaction limit agricultural productivity and may compromise the sustainability of ecosystems (e.g., Amazonian). Only few studies show the effect of land use and soil management systems in the Amazon region, which hinders the understanding of this effect on this ecosystem. Therefore, the objective was to evaluate the effect of land use and soil management systems on physical attributes and on the carbon stock of an Oxisol in the Amazon. Evaluations were performed at 0-10, 10-20, 20-30 and 30-40 cm of soil subjected to the use and management systems: minimum tillage, conventional tillage, native pasture and native forest. The highest densities were observed in the soil area of Brachiaria brizantha implanted after conventional tillage and native pasture area. The highest levels of total organic carbon and the largest stocks of carbon in the soil were found in forest area, and B. brizantha was established after minimum tillage, at 0-10 cm depth. Therefore, the minimum tillage is the most indicated land use and soil management system to introduce B. brizantha in the Amazon. |

Solos com baixos teores de matéria orgânica e alta compactação limitam a produtividade agrícola e podem comprometer a sustentabilidade dos ecossistemas (e.g. Amazônico). Existem poucos estudos demonstrando o efeito de sistemas de uso e manejo em solos da região Amazônica, o que dificulta a compreensão desse efeito sobre a sustentabilidade desse ecossistema. Diante disso, objetivou-se neste artigo avaliar o efeito de sistemas de uso e manejo do solo em atributos físicos e no estoque de carbono em um Latossolo Vermelho- Amarelo na Amazônia. As avaliações foram realizadas nas profundidades de 0-10; 10-20; 20-30 e 30-40 cm de solo submetido aos sistemas de uso e manejo: cultivo mínimo, plantio convencional, pastagem nativa e floresta nativa. As maiores densidades do solo foram verificadas em área de pastagem de Brachiaria brizantha, implantada após sistema de preparo convencional, e em área de pastagem nativa. Os maiores teores de carbono orgânico total e estoque de carbono no solo foram encontrados em área de floresta nativa e de B. brizantha implantada após cultivo mínimo, na camada de 0-10 cm de profundidade. Portanto o cultivo mínimo é o sistema de uso e manejo do solo mais indicado para a introdução da B. brizantha na Amazônia.Universidade Federal Rural da Amazônia/UFRA2018-09-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ajaes.ufra.edu.br/index.php/ajaes/article/view/2808Amazonian Journal of Agricultural Sciences Journal of Agricultural and Environmental Sciences; Vol 61 (2018): RCARevista de Ciências Agrárias Amazonian Journal of Agricultural and Environmental Sciences; v. 61 (2018): RCA2177-87601517-591Xreponame:Revista de Ciências Agrárias (Belém.
