Resumo: | Preparation procedures affect the physical properties of soil, which over time can lead to a reduction in its quality. Parameters related to soil structure such as state of aggregation, bulk density and porosity are commonly used to infer the physical quality of agricultural soils. Thus, this study aimed to assess the state of aggregation, the flocculation index, bulk density and porosity of Yellow Ultisol in Brazil’s northeastern semiarid region in function of tillage systems and the frequency of operations. The experiment was conducted in an area of the Universidade Federal do Vale do São Francisco - UNIVASF, and treatments consisted of combinations of different types and intensities of tillage operations, which were: no tillage, chisel plow, tandem disc harrow, offset disc harrow with discs of 0.56 m and offset disc harrow with discs of 0.61 m; which received different number of operations (one, two and three). A randomized block design was used with four replications, with treatments arranged in subdivided plots, where the tillage systems make up the plots and number of operations are the subplots. Tilled and undisturbed soil samples were collected to evaluate the stability of soil aggregates, bulk density, porosity and flocculation index. No significant differences were obtained for the parameters Geometric Mean Diameter, mean weighted diameter and aggregate stability index when comparing the tillage systems used. The bulk density and porosity of the soil were not significantly affected by tillage systems or the number of operations. |

Parâmetros relacionados à estrutura do solo tais como agregação, densidade e porosidade, são comumente utilizados para inferir sobre a qualidade física dos solos agrícolas. Assim, objetivou-se avaliar o estado de agregação, o índice de floculação, a densidade e a porosidade total de Argissolo Amarelo do semiárido nordestino em função dos sistemas de preparo e do número de operações. O experimento foi desenvolvido em área pertencente à Universidade Federal do Vale do São Francisco – UNIVASF, sendo os tratamentos compostos pela combinação de diferentes tipos de preparo e intensidades de operação, os quais foram, respectivamente: sem preparo, preparo com escarificador, com grade leve em “tandem”, grade leve “off-set” (discos de 0,56 m de diâmetro) e, grade leve “off-set” (discos de 0,61 m de diâmetro); uma, duas e três operações. Utilizou-se o delineamento em blocos casualizados com quatro repetições, com os tratamentos dispostos em esquema de parcelas subdivididas, sendo os sistemas de preparo dispostos nas parcelas e o número de operação nas subparcelas. Foram coletadas amostras deformadas e indeformadas de solo para avaliação da estabilidade dos agregados do solo, densidade do solo, porosidade total e índice de floculação. Não foram obtidas diferenças significativas para os parâmetros Diâmetro Médio Geométrico (DMG), Diâmetro Médio Ponderado (DMP) e Índice de Estabilidade de Agregados (IEA) quando comparados os sistemas de preparo utilizados. A densidade e a porosidade total do solo também não foram significativamente afetadas pelos sistemas de preparo e o número de operações.Universidade Federal de Viçosa - UFV2013-10-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/40310.13083/reveng.v21i5.444Engineering in Agriculture; Vol. 21 No. 5 (2013); 456-464Revista Engenharia na Agricultura - REVENG; v. 21 n. 5 (2013); 456-4642175-68131414-398410.13083/reveng.v21i5reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/403/295Feitosa, Jardênia RodriguesOlszevski, NelciCortez, Jorge WilsonNagahama, Hideo Jesusinfo:eu-repo/semantics/openAccess2023-01-19T13:19:07Zoai:ojs.periodicos.ufv.br:article/403Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T13:19:07Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false |
