Resumo: The recovery of soils with high salinity and alkalinity requires the use of products that decrease the pH and exchangeable sodium content, in order to improve their fertility. This study aimed at evaluating the effect of calcium sulfate and elementary sulfur on the chemical properties of a soil with high contents of soluble salts and exchangeable sodium. Two experiments were carried out in a greenhouse using samples of a sandy loam saline-sodic soil. In the first experiment, four soil correction treatments (without correction, without correction and washing, corrected with calcium sulfate, and corrected with elementary sulfur) were tested. In the second experiment, five elementary sulfur doses (0 kg ha-1, 400 kg ha-1, 800 kg ha-1, 1,200 kg ha-1 and 1,600 kg ha-1) were tested. The elementary sulfur and calcium sulfate positively affected the chemical properties of the soil, improving its fertility. The elementary sulfur, besides improving the soil chemical properties, is more efficient than calcium sulphate in decreasing alkalinity, however, the use of this product requires the application of additional calcium to the soil. Due to its low clay content, the simple washing process decreases soil salinity and sodicity.

Objetivou-se avaliar o efeito do sulfato de cálcio e do enxofre elementar sobre os atributos químicos de um solo com altos teores de sais solúveis e Na trocável. Dois experimentos foram conduzidos em casa-de-vegetação, utilizando-se amostras de um Neossolo Flúvico sódico sálico de textura franco-arenosa. No primeiro experimento, foram testados quatro tratamentos referentes à correção do solo (sem corretivo, sem corretivo e sem lavagem, corrigido com sulfato de cálcio e corrigido com enxofre elementar). No segundo experimento, os tratamentos compreenderam cinco doses de enxofre elementar (0 kg ha-1, 400 kg ha-1, 800 kg ha-1, 1.200 kg ha-1 e 1.600 kg ha-1). O enxofre elementar e o sulfato de cálcio influenciaram positivamente os atributos químicos do solo, proporcionando melhor fertilidade. O enxofre elementar, além de melhorar os atributos químicos desse solo, é mais eficiente que o sulfato de cálcio na diminuição de sua alcalinidade, contudo, o uso desse produto requer a aplicação de fonte adicional de cálcio ao solo. Devido ao seu baixo teor de argila, a simples lavagem contribui para diminuir a salinidade e sodicidade do solo.Escola de Agronomia - Universidade Federal de Goiás2015-12-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/37090Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 45, n. 4, Oct./Dec. 2015; 388-396Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 45, n. 4, out./dez. 2015; 388-396Pesquisa Agropecuária Tropical; v. 45, n. 4, out./dez. 2015; 388-3961983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/37090/19675Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessAraujo, Josinaldo LopesSevero, Pedro Jorge da SilvaLucena, Francisco Tarcísio CartaxoVeriato, Rafael GuimarãesPaiva, Kariolania Fortunato de2020-07-13T16:33:08Zoai:ojs.revistas.ufg.br:article/37090Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:09.631573Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
