Resumo: | Irrigated cocoa cultivation opened the way for production in Coastal Tablelands soils. However, in this region, the cohesive layer formed near the surface can be a limiting factor for production. The knowledge of physical soil water attributes enables the efficient irrigation management of cohesive soils. This study characterized and modeled the spatial variability of saturated hydraulic conductivity (K0) in a Distrocoeso Oxisoil of the Recôncavo Baiano Coastal Tablelands. The soil sampling was performed as undeformed structures from 50 spaced points in an 8.0 to 8.0 m area, at three different depths in the experimental area of the Federal University of Bahia Recôncavo in the Cruz das Almas–BA cultivated with cocoa (‘CCN 51’). In the laboratory, K0 was determined by permeameter method constant load, and the pore size distribution was determined using the voltage table and the soil density (Ds). Data were analyzed using descriptive statistics and geostatistics. On average, the K0 values were 40.41, 26.49, and 37.82 mm-1 h-1 at the depths from 0.0–0.15 m, 0.15–0.30, and 0.30–0.45 m. The Gaussian model was the best fit to the K0 data set. For soil class, the K0 showed a strong spatial dependence due to their relationship with the physical properties of the soil, its use, and handling. Since an important attribute for the delimitation of homogeneous areas for specific site management purposes as well be considered. |

Porém, nesta região, a camada coesa formada próxima da superfície, pode ser um fator limitante para sua produção. O conhecimento dos atributos físico-hídricos do solo possibilitará um manejo eficiente da irrigação em solos coesos. Com isso, objetivou-se caracterizar e modelar a variabilidade espacial da condutividade hidráulica saturada em Latossolo Amarelo Distrocoeso dos Tabuleiros Costeiros do Recôncavo Baiano. A amostragem de solo na estrutura indeformada foi realizada em 50 pontos espaçados de 8,0 em 8,0 m, em três diferentes profundidades na área experimental da Universidade Federal do Recôncavo da Bahia, em Cruz das Almas - BA, cultivada com cacau CCN 51. Determinou-se em laboratório a K0 utilizando permeâmetro de carga constante, distribuição de poros utilizando mesa de tensão e a densidade do solo. Realizou-se análises descritiva e de geoestatística. Em média os valores da K0 foram 40,41 mm h-1, 26,49 mm h-1 e 37,82 mm h-1 nas profundidades 0,0-0,15 m, 0,15-0,30 m e 0,30-0,45 m. O modelo gaussiano foi o que melhor se ajustou ao conjunto de dados da K0. Para a classe de solo avaliada, a K0 apresentou uma forte dependência espacial devido a sua relação com as propriedades físicas do solo, seu uso e manejo. Podendo assim, ser considerado um importante atributo para a delimitação de zonas homogêneas para fins de manejo sítio específicos.Universidade Federal Rural do Semi-Árido2019-08-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/835210.1590/1983-21252019v32n323rcREVISTA CAATINGA; Vol. 32 No. 3 (2019); 786-794Revista Caatinga; v. 32 n. 3 (2019); 786-7941983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/8352/10064Copyright (c) 2019 Revista Caatingainfo:eu-repo/semantics/openAccessSilva, Gerlange Soares daSilva, Jucicléia Soares daPereira, Francisco Adriano de CarvalhoSantana, Rodrigo AlmeidaFirmo, Rafael SilvaLopes Sobrinho, Oswaldo Palma2023-07-20T17:40:02Zoai:ojs.periodicos.ufersa.edu.br:article/8352Revistahttps://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:2024-04-29T09:46:39.070714Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
