Resumo: | The management of perennial crops could encourage the improvement of the soil, making it more productive, provided that appropriate agronomic practices are adopted. In order to evaluate the structure of a Cerrado Latosol subjected to soil management that adopts the use of high doses of gypsum and brachiaria on the coffee plants interrow, we studied the stability of aggregates and total soil organic carbon after two years of deployment of coffee. Soil samples were collected at 5 and 15 cm of depth in the crop coffee row located in the Alto São Francisco region, Minas Gerais states. The treatments were: G-0, no gypsum on the row, G-7, 7.0 Mg ha–1 of gypsum distributed in the coffee row, G-28, 28 Mg ha–1 of gypsum distributed in the coffee row, G-56, 56 Mg ha–1 of gypsum distributed in the row, CV-0, conventional management without gypsum CV-0 conventional tillage without gypsum in the row and grasses between row Brachiaria sp. between rows of coffee plants. Chemical analyzes were performed to determine the cations K+, Ca+2, Mg+2, P, and Al+3, total organic carbon and physical analysis of soil aggregate stability. It was determined the mean weight diameter and geometric mean diameter of aggregates retained on sieves with diameters ranging from 4 to 0.105 mm. All treatments were found more than 90% of aggregates with a diameter >2 mm suggesting that the management adopted a positive influence soil aggregate stability. The total organic carbon were positive and significantly correlated with aggregation. The dose of gypsum 7 t ha–1 positively altered the aggregation of soil specially in the superficial layer (15 cm). |

A gestão de culturas perenes poderia incentivar a melhoria do solo, tornando-o mais produtivo , desde que práticas agronômicas adequadas sejam adotadas. A fim de avaliar a estrutura de um Latossolo de Cerrado submetido a manejo do solo que adota o uso de altas doses de gesso e braquiária nas plantas de café entre filas , estudamos a estabilidade de agregados e carbono orgânico total do solo após dois anos de implantação do café. As amostras de solo foram coletadas em 5 e 15 cm de profundidade na linha de colheita de café localizada na região do Alto São Francisco, Minas Gerais . Os tratamentos foram: G- 0, sem gesso na linha , o G- 7 , 7,0 Mg ha- 1 de gesso distribuído na linha de café, G- 28, 28 Mg ha- 1 de gesso distribuído na linha de café, G- 56, 56 Mg ha- 1 de gesso distribuído na linha , CV- 0, manejo convencional sem gesso CV- 0 preparo convencional sem gesso na linha e gramíneas entre linha Brachiaria sp. entre fileiras de plantas de café. As análises químicas foram realizadas para determinar os cátions K +, Ca +2, Mg +2 , P e Al +3, carbono orgânico total e análise física de estabilidade dos agregados do solo. Determinou-se o diâmetro médio ponderado e diâmetro médio geométrico de agregados retidos em peneiras com diâmetros variando de 4 a 0,105 milímetro . Todos os tratamentos foram encontrados mais de 90% de agregados com diâmetro > 2mm sugerindo que a administração adotou uma influência positiva da estabilidade de agregados do solo . O carbono orgânico total foram positivos e significativamente correlacionada com agregação. A dose de gesso 7 t ha-1 alterou positivamente a agregação do solo , especialmente na camada superficial ( 15 cm) .Universidade Federal Rural da Amazônia/UFRA2013-04-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ajaes.ufra.edu.br/index.php/ajaes/article/view/718Amazonian Journal of Agricultural Sciences Journal of Agricultural and Environmental Sciences; Vol 56 No 1 (2013): RCA; 25 - 32Revista de Ciências Agrárias Amazonian Journal of Agricultural and Environmental Sciences; v. 56 n. 1 (2013): RCA; 25 - 322177-87601517-591Xreponame:Revista de Ciências Agrárias (Belém.
