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.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.porUniversidade Federal de Minas GeraisUFMGBrasilICA - INSTITUTO DE CIÊNCIAS AGRÁRIASBrazilian Journal of Animal and Environmental ResearchSolosPastagensLavouraPecuariaFlorestasSistemas de integração lavoura-pecuária-florestaQualidade física do soloMonitoramentoAtributos físicos do solo sob diferentes usos da terra do Cerrado de Minas GeraisPhysical attributes of the soil under different land uses in the Cerrado of Minas Geraisinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://ojs.brazilianjournals.com.br/ojs/index.php/BJAER/article/view/20438/16351Daniela 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:UFMGLICENSELicense.txtLicense.txttext/plain; charset=utf-82042https://repositorio.ufmg.br/bitstream/1843/52086/1/License.txtfa505098d172de0bc8864fc1287ffe22MD51ORIGINALAtributos físicos do solo sob diferentes usos da terra do Cerrado de Minas Gerais_Leidivan Almeida Frazão.pdfAtributos físicos do solo sob diferentes usos da terra do Cerrado de Minas Gerais_Leidivan Almeida Frazão.pdfapplication/pdf475624https://repositorio.ufmg.br/bitstream/1843/52086/2/Atributos%20f%c3%adsicos%20do%20solo%20sob%20diferentes%20usos%20da%20terra%20do%20Cerrado%20de%20Minas%20Gerais_Leidivan%20Almeida%20Fraz%c3%a3o.pdf5b730586e34e723dacbafb9160a6e1a0MD521843/520862023-04-17 19:07:26.862oai:repositorio.ufmg.br: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Repositório InstitucionalPUBhttps://repositorio.ufmg.br/oaiopendoar:2023-04-17T22:07:26Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false
