Resumo: | Soil liming is a common practice in agriculture. It aims to reduce soil acidity and to supply calcium and magnesium. Lime, however, is not easily soluble in the soil, and its reaction products are often concentrated in the application zone, which is mainly the topsoil layer. In order to increase the concentration of nutrients in deeper layers, agricultural gypsum—a byproduct of phosphoric acid production process, rich in calcium and sulfur—is used. In this context, the objective of this study was to evaluate the chemical attributes of the oxysoil and the corn´s yield to the application of gypsum associated with potassium (K) rates. The study was developed in Uberaba city, Minas Gerais state, Brazil. The factorial scheme was used 5x5, with five rates of K (0, 100, 180, 240, 360 kg ha-1 K2O) and five gypsum rates (0, 500, 1000, 2000, 4000 kg ha-1) in a randomized complete block design with four replications. The soil chemical attributes were evaluated at 0.0-0.20 m and 0.20-0.40 m depth and the biometric and productive attributes of corn. The application of gypsum resulted in the increase of calcium (Ca) and sulfur (S) contents in all depths; reduced the levels of pH, manganese, potential acidity (H + Al) in the 0.0-0.20 m depth, and increase the levels of base of saturation and sum of bases on the 0.20-0.40 m depth. Corn yield and biometric attributes no were influenced by the factors evaluated. |

Esta prática visa reduzir a acidez do solo, além de fornecer cálcio e magnésio. Contudo, devido ao fato de o calcário apresentar baixa solubilidade no solo, os produtos de sua reação ficam retidos na camada onde o produto foi aplicado, a qual geralmente é na camada superficial do solo. Para se aumentar a concentração de nutrientes em camadas mais profundas, o gesso agrícola - um subproduto da produção de ácido fosfórico, rico em cálcio e enxofre tem sido usado. Neste contexto, o objetivo deste trabalho foi avaliar a influência da aplicação de diferentes doses de gesso em associação a doses de potássio, nos atributos químicos do solo e na produtividade de grãos de milho. O estudo foi conduzido no Instituto Federal de Educação, Ciência e Tecnologia do Triângulo Mineiro (IFTM), Campus Uberaba, localizado no município de Uberaba-MG, Brasil. O experimento foi instalado em esquema fatorial 5x5, sendo cinco doses de gesso (0, 500, 1000, 2000 e 4000 kg ha-1) e cinco doses de K2O (0, 100, 180, 240 e 360 kg ha-1) no delineamento em blocos completos casualizados, com quatro repetições. Os atributos químicos do solo foram avaliados nas camadas de 0,0 a 0,20 m e de 0,20 a 0,40 m, além das características biométricas e produtivas da cultura do milho. A aplicação de gesso resultou no aumento de cálcio e enxofre em ambas as profundidades; reduziu os níveis de pH, manganês, acidez potencial (H + Al) na camada de 0,0-0,20m; e, aumentou os níveis de saturação por bases e soma de bases na camada de 0,20-0,40 m. A produção de milho não foi influenciada pelos fatores avaliados.EDUFU2020-04-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/4244310.14393/BJ-v36n3a2020-42443Bioscience Journal ; Vol. 36 No. 3 (2020): May/June; 810-826Bioscience Journal ; v. 36 n. 3 (2020): Maio/Junho; 810-8261981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/42443/28622Brazil; ContemporaryCopyright (c) 2020 Hamilton César de Oliveira Charlo, Juliano da Silva Martins de Almeida, Regina Maria Quintão Lana, Renata Castoldi, Édimo Fernando Alves Moreira, Moilton Ribeiro Franco Júnior, Welson Barbosa Santoshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCharlo, Hamilton César de OliveiraAlmeida, Juliano da Silva Martins deLana, Regina Maria QuintãoCastoldi, RenataMoreira, Édimo Fernando Alves Franco Júnior, Moilton RibeiroSantos, Welson Barbosa2022-06-14T18:57:00Zoai:ojs.www.seer.ufu.br:article/42443Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-06-14T18:57Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
