Resumo: In saline-sodic soils, even with gypsum appliance, immediate leaching of salts can promote the dispersion of clay and the impermeability of the soil, hindering soil recovery. The objective of this work was to evaluate the influence of the parceled leaching on diverse chemical characteristics of a saturated soil paste extract, in saline-sodic soil samples. Columns of PVC were filled with samples of soils Fluvent of Ipanguaçu, RN, Fluvent of Caicó, RN and Vertisol (V) of Mossoró, RN, Brazil. The management consisted in applying leaching solution, with CaCl2 and MgCl2, with the total volume and parceled in two, four and six times, with intervals of 22 days among appliances. In the saturated soil paste extract, the electrical conductivity, pH and concentration of sodium, calcium, magnesium and sulfates were determined. The pH and cations exchangeable were determined in the soil. The application of gypsum and water depth reduce the exchangeable sodium percentage and the electrical conductivity of saturated soil paste extract to values lower that 15% and 4 dS m-1, respectively, mainly when the water depth is applied in parcel.

O objetivo deste trabalho foi avaliar a influência do parcelamento da lâmina de lixiviação sobre diversas características químicas do extrato da pasta de saturação e do solo, em amostras de solos com características salino-sódicas. Colunas de PVC foram preenchidas com amostras de um Neossolo Flúvico de Ipanguaçu, RN; de um Neossolo Flúvico de Caicó, RN, e de um Vertissolo (V) de Mossoró, RN. Os manejos consistiram na aplicação da solução de lixiviação, com CaCl2 e MgCl2, com o volume total e parcelado em duas, quatro e seis vezes, com intervalos de 22 dias entre cada aplicação. Foram determinadas, no extrato da pasta de saturação, a condutividade elétrica e as concentrações de sódio, cálcio, magnésio e sulfatos, e no solo, os cátions trocáveis e o pH. As aplicações de gesso e de lâminas de lixiviação reduzem a porcentagem de sódio trocável e a condutividade elétrica do extrato de saturação a valores inferiores a 15% e 4 dS m-1, respectivamente, principalmente, quando a lâmina de lixiviação é aplicada de forma parcelada.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraRuiz, Hugo AlbertoSampaio, Regynaldo ArrudaOliveira, Maurício deVenegas, Victor Hugo Alvarez2004-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6885Pesquisa Agropecuaria Brasileira; v.39, n.11, nov. 2004; 1119-1126Pesquisa Agropecuária Brasileira; v.39, n.11, nov. 2004; 1119-11261678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6885/3941info:eu-repo/semantics/openAccess2014-09-03T18:12:36Zoai:ojs.seer.sct.embrapa.br:article/6885Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-03T18:12:36Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
