Resumo: The aim of the present study was to evaluate the electrical conductivity (EC) soil profile in function of chemical fertilizer applied through fertigation and manual methods under the canopy. The crop was drip irrigated and irrigation was performed when the average voltage observed in “Watermark” sensors installed at 0.10 m depth reached 21 kPa. The irrigation depth was calculated using the average reading of soil water potential observed on the sensors installed at 0.10 and 0.30 m deep and the soil water retention curve. Under the tree canopy, in the drip bulb region, we installed 25 soil solution extractors at 0.10, 0.20, 0.30, 0.40 and 0.50 m deep and distant plant of 0, 10, 0.20, 0.30, 0.40 and 0.50 m. Sampling was conducted in irrigated and non irrigated plants during fertilization (October-March), for two years (2008/2009 and 2009/2010). The EC evaluations were performed 24 hours after fertilization, and between fertilizations. The results indicated that for irrigated and not irrigated plants, the EC of the soil showed spatial dependence. The application of fertilizer through water irrigation reduces EC of soil when compared to manual application. Doses and sources of fertilizer used do not promote soil salinization.

A cultura foi irrigada por gotejamento e a irrigação é realizada quando a tensão média observada em sensores “Watermarck” instalados a 0,10 m de profundidade atingia 21 kPa. A lâmina aplicada foi calculada com base na média de leitura do potencial de água no solo observada nos sensores instalados a 0,10 e 0,30 m de profundidade e na curva de retenção de água do solo. Sob a copa das plantas, na região do bulbo molhado, foram instalados 25 extratores de solução do solo a 0,10; 0,20; 0,30; 0,40 e 0,50 m de profundidade e distantes da planta de 0,10; 0,20; 0,30, 0,40 e 0,50 m. A amostragem foi realizada em plantas irrigadas e não irrigadas no período de adubação (outubro a março), durante dois anos (2008/2009 e 2009/2010). As avaliações da CE foram realizadas 24 horas após a adubação e entre as adubações. Os resultados indicaram que, para as plantas irrigadas e não irrigadas, a CE do solo apresentou dependência espacial. A aplicação de adubo via água de irrigação reduz a CE do solo quando comparado com a aplicação manual. As doses e fontes de fertilizantes utilizadas não promoverão a salinização do solo.Editora UFLA2011-09-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/381Coffee Science - ISSN 1984-3909; Vol. 6 No. 1 (2011); 55-64Coffee Science; Vol. 6 Núm. 1 (2011); 55-64Coffee Science; v. 6 n. 1 (2011); 55-641984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/381/pdfCopyright (c) 2011 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessConceição Rezende, FátimaBarbiere Ribeiro, VictorFernandes Ávila, LeoAlves de Faria, ManoelRogério de Mello, Carlos2013-02-24T14:16:35Zoai:coffeescience.ufla.br:article/381Revistahttps://coffeescience.ufla.br/index.php/CoffeesciencePUBhttps://coffeescience.ufla.br/index.php/Coffeescience/oaicoffeescience@dag.ufla.br||coffeescience@dag.ufla.br|| alvaro-cozadi@hotmail.com1984-39091809-6875opendoar:2024-05-21T19:53:39.846999Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true
