Resumo: The objective of this study was to evaluate the physical attributes of the soil after the conversion of degraded pasture into integrated crop-livestock-forest systems (ICLF) and forage crops in Curvelo, Minas Gerais.Soil samples were collected from depths of 0-5, 5-10, 10-20, 20-30 cm. Theevaluated attributes were soil density (SD)and particlesdensity (PD), total porosity (TP), geometric mean diameter (GMD)and weighted meandiameter (WMD) and aggregate stability index (ASI) in seven treatments:ICLF withcultivation eucalyptus intercropped with corn and marandu grass (ICLF M), corn and java(ICLF J)and corn, marandu grass and java (ICLF J+M); monoculture of marandu grass (MAR) and java (JAVA); maranduconsortium with java (J+M)anddegraded pasture (PAST).The results were submitted to analysis of variance andstatistical significance of differences between treatment means were assessed by Tukey test (p <0.05).The lowest SDvalueswere observed in JAVA (0-5 cm) and the highest TP valuesin JAVA (0-5 cm). The highest GMDand WMD(10-20 cm) were found in PAST. For PD and ASIno significant differences were found between treatments and depths.

Coletaram-se amostras nas profundidades de 0-5, 5-10, 10-20 e 20-30 cm. Os atributos avaliados foram densidade do solo (DS) e de partículas (DP), porosidade total (PT), diâmetro médio geométrico (DMG) e ponderado (DMP) e índice de estabilidade de agregados (IEA)em sete tratamentos: ILPF com cultivo de eucalipto consorciado com milho e capim-marandu (ILPF M), milho e java (ILPF J) e milho, marandu e java (ILPF J+M); monocultivo de capim-marandu (MAR) e java (JAVA); consórcio de marandu com java (J+M) e pastagem degradada (PAST). Os resultados foram submetidos à análise de variância e a diferença entre médias de tratamentos foi avaliada pelo teste de Tukey (p<0,05).O menor valorde DS foi observado no JAVA (0-5 cm) e o maior valor de PT no JAVA (0-5 cm). O maior DMP e DMG (10-20 cm) foi encontrado no PAST. Para DP e IEA não se encontraram diferenças significativas entre tratamentos e profundidades.Universidade Federal de Minas GeraisBrasilICA - INSTITUTO DE CIÊNCIAS AGRÁRIASUFMG2023-04-17T21:22:32Z2023-04-17T21:22:32Z2020info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdf2595-573Xhttp://hdl.handle.net/1843/52086porBrazilian Journal of Animal and Environmental ResearchDaniela Aparecida FreitasIgor Costa de FreitasLeidivan Almeida FrazãoNayara Christina Almeida AraújoLeliane Raynne Duarte SilvaMárcia Vitória Santosinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMG2023-04-17T22:07:26Zoai:repositorio.ufmg.br:1843/52086Repositório InstitucionalPUBhttps://repositorio.ufmg.br/oairepositorio@ufmg.bropendoar:2023-04-17T22:07:26Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false
