Resumo: | Compaction modifies the structural arrangement and essential functions of soil pores. In this context, the objective of this study was to evaluate the impact of different compaction levels in an Argissolo Amarelo (Ultisol) on the physical-hydraulic attributes that indicate the functionality of soil pores. The experiment was conducted using 0.05 x 0.05 m soil cylinders with 4 compaction levels (CL): 61, 71, 82 and 92%, and at each CL, the pore-size distribution, intrinsic soil air permeability (Kair), pore continuity index N, soil water characteristic curve and cumulative pore-size frequency were quantified under a completely randomized design. The increase in CL did not impact the amount of micropores, but reduced the amount of macropores to values lower than the minimum required from the CL of 82%. The increase in CL caused reductions in N index, Kair and aeration porosity, but with different amplitude depending on the CL and the water tension in the soil. CL above 61% reduced the water content at the tension range between 0 and 6 kPa and, as a consequence, increased the percentage of aeration pores, besides promoting greater water retention within the range between 10 and 1500 kPa. The evaluation of the physical-hydraulic attributes of the Argissolo Amarelo (Ultisol) revealed that the increase in the compaction level altered soil structure, reduced and formed pores that were poorly continuous and less permeable to air flow and, despite the higher water retention at the higher tensions, promoted lower available moisture content. |

O trabalho teve como objetivo avaliar o impacto de diferentes graus de compactação em um Argissolo Amarelo sobre os atributos físicos-hídricos indicadores da funcionalidade dos poros. Foram utilizados cilindros de solo 0.05 x 0.05 m em 4 graus de compactação (GC): 61, 71, 82 e 92%, e em cada GC, foi quantificado, sob um delineamento inteiramente aleatorizado, a distribuição de poros por tamanho, permeabilidade intrínseca do solo ao ar (Kar), índice N de continuidade de poros, curva caraterística da água no solo e frequência acumulada de poros. O incremento no GC não causou impacto na quantidade de microporos, mas diminuiu a quantidade de macroporos para valores menores que o mínimo requerido a partir do GC de 82%. O aumento no CG provocou redução no índice N, Kar e porosidade de aeração, porém com amplitude diferente dependendo do GC e da tensão da água no solo. Os GC acima de 61% reduziram o conteúdo de água na faixa de tensão entre 0 até 6 kPa e, como consequência, aumentaram a porcentagem de poros de areação; enquanto na faixa entre 10 e 1500 kPa proporcionaram maior retenção de água. A avaliação dos atributos físicos-hídricos do Argissolo Amarelo revelou que o incremento na compactação alterou a estrutura do solo, reduziu e formou poros pouco contínuos, e menos permeável ao fluxo de ar; e apesar da maior retenção de água nas tensões mais elevadas, promoveu menor conteúdo de umidade disponível.Universidade Federal Rural do Semi-Árido2022-09-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/994010.1590/1983-21252022v35n416rcREVISTA CAATINGA; Vol. 35 No. 4 (2022); 884-893Revista Caatinga; v. 35 n. 4 (2022); 884-8931983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/9940/11054Copyright (c) 2022 Revista Caatingainfo:eu-repo/semantics/openAccessSilva, Francisca Gleiciane daAssis Junior , Raimundo Nonato deToma, Raul Shiso Oliveira, Lucas de Sousa Marques, Edilaine da SilvaMota, Jaedson Cláudio Anunciato2023-06-30T18:03:55Zoai:ojs.periodicos.ufersa.edu.br:article/9940Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:54.281410Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |

Compaction modifies the structural arrangement and essential functions of soil pores. In this context, the objective of this study was to evaluate the impact of different compaction levels in an Argissolo Amarelo (Ultisol) on the physical-hydraulic attributes that indicate the functionality of soil pores. The experiment was conducted using 0.05 x 0.05 m soil cylinders with 4 compaction levels (CL): 61, 71, 82 and 92%, and at each CL, the pore-size distribution, intrinsic soil air permeability (Kair), pore continuity index N, soil water characteristic curve and cumulative pore-size frequency were quantified under a completely randomized design. The increase in CL did not impact the amount of micropores, but reduced the amount of macropores to values lower than the minimum required from the CL of 82%. The increase in CL caused reductions in N index, Kair and aeration porosity, but with different amplitude depending on the CL and the water tension in the soil. CL above 61% reduced the water content at the tension range between 0 and 6 kPa and, as a consequence, increased the percentage of aeration pores, besides promoting greater water retention within the range between 10 and 1500 kPa. The evaluation of the physical-hydraulic attributes of the Argissolo Amarelo (Ultisol) revealed that the increase in the compaction level altered soil structure, reduced and formed pores that were poorly continuous and less permeable to air flow and, despite the higher water retention at the higher tensions, promoted lower available moisture content. |
