Resumo: | The Least Limiting Water Range (LLWR) is an indicator of soil physical quality for plant growth determined not only by the availability of water, but also by aeration and soil resistance to root penetration. The objective of this work was to evaluate the LLWR and the critical values of bulk density of a Typic Hapludult soil under the Atlantic Forest, degraded pasture and revegetation with tree legumes. The area, located in Conceição de Macabu, RJ state, is constituted of five vegetation coverages. Of these, three were pure plantations of the Acacia auriculiformis, Mimosa caesalpiniifolia e Inga edulis tree legumes, implanted in 1998 in plots of 1.500 m2. The others, used as reference and adjacent to the legume plantations, were a degraded pasture and a forest fragment of Atlantic Forest. Soil samples, collected in volumetric rings in the 0-0.10 and 0.10-0.20 m depth layers, were used to obtain the water retention curve, penetration resistance curve and LLWR as a function of density. In no area or layer has been verified restrictions to soil aeration. On the other hand, RP values above the critical limit of 3.0 MPa were verified in most cases, making the LLWR smaller than the field capacity. Critical soil densities to plants for mechanical and water restrictions (DscRP and DscIHO) were higher under capoeira. The areas under leguminous trees, showing high average densities and low values of critical densities DscRP and DscIHO, similar to those of the area under pasture. It can be concluded that the soil under capoeira shows resilience to the compaction process, and that after 17 years of revegetation with leguminous trees there was no consistent evidence of structural soil. |

O objetivo do trabalho foi avaliar a eficiência da revegetação com as leguminosas arbóreas Acácia, Sábia e Ingá, para a recuperação da qualidade física de um Argissolo Vermelho-Amarelo inicialmente sob pastagem degradada, utilizando como indicador o intervalo hídrico ótimo e as densidades críticas dele decorrentes. A área, localizada em Conceição de Macabú, Rio de Janeiro, constitui-se de cinco coberturas vegetais. Dessas, três foram plantios puros das leguminosas arbóreas acácia, sábia, e ingá, implantadas em 1998, em parcelas de 1500 m2. As outras áreas, utilizadas como referência e adjacentes aos plantios de leguminosas, foram uma pastagem degradada e um fragmento florestal de Mata Atlântica. Amostras de solo, coletadas em anéis volumétricos nas camadas 0-0,10 e 0,10-0,20 m de profundidade, foram utilizadas para a obtenção da curva de retenção de água, da curva de resistência à penetração e do IHO em função da densidade. Em nenhuma área ou camada foram verificadas restrições à aeração do solo. Por outro lado, valores de resistência à penetração superiores ao limite crítico de 3,0 MPa foram verificados em grande parte dos casos, fazendo com que o IHO fosse menor que a água disponível. As densidades do solo críticas às plantas quanto a restrições mecânicas e hídricas (DscRP e DscIHO) foram mais altas sob capoeira. As áreas sob leguminosas arbóreas apresentaram elevadas densidades médias e baixos valores de densidades críticas DscRP e DscIHO, similares às da área sob pastagem. Pode-se concluir que o solo sob capoeira apresenta resiliência frente ao processo de compactação, e que após 17 anos da revegetação com leguminosas arbóreas não houve evidências consistentes de recuperação estrutural do solo.Universidade Federal de Santa Maria2021-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3347410.5902/1980509833474Ciência Florestal; Vol. 31 No. 2 (2021); 658-682Ciência Florestal; v. 31 n. 2 (2021); 658-6821980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/33474/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/33474/htmlCopyright (c) 2021 Ciência Florestalinfo:eu-repo/semantics/openAccessFaustino, Lucas LuísMarciano, Cláudio Roberto2021-08-24T13:31:11Zoai:ojs.pkp.sfu.ca:article/33474Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2021-08-24T13:31:11Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
