Resumo: Agricultural gypsum has been suggested to enhance the soil chemical characteristics in depth for favoring the movement of some nutrients into lower soil layers. However, the effectiveness of such practice as a tool for getting a better distribution of some nutrients in the profile of clayey soils and in consolidated no-tillage areas is questionable. This study aimed at evaluating the impact of agricultural gypsum rates and a single mechanical intervention (plowing + harrowing twice) conducted only at the installation of the experiment on the distribution gradient of some nutrients in the soil profile. Doses of 0 tons ha-1, 2 tons ha-1, 4 tons ha-1 and 6 tons ha-1 of agricultural gypsum were broadcasted in the early stages of development of white oat. Four crops of soybean/maize and oat as a winter cover crop were grown. Soil management with a single plowing and harrowing operation, in areas under long-term no-tillage system, does not minimize the soil fertility gradient. For this soil with clay content above 70 %, the gypsum was inefficient in promoting the vertical mobility of cations at 36 months after its implementation, being the effects limited to the first 0.10 m of depth, differently from that observed for the S-SO42- anion.

Porém, questiona-se a efetividade dessa prática como ferramenta para uma melhor distribuição de alguns nutrientes no perfil de solos de textura argilosa e em áreas de plantio direto já consolidado. Objetivou-se avaliar o impacto de doses de gesso agrícola e de uma única intervenção mecânica (aração + duas gradagens) efetuada somente na instalação do experimento sobre o gradiente de distribuição de alguns nutrientes no perfil do solo. Doses de 0 t ha-1, 2 t ha-1, 4 t ha-1 e 6 t ha-1 de gesso agrícola foram aplicadas a lanço, nos estádios iniciais de desenvolvimento da aveia branca. Foram efetuados quatro cultivos da sucessão soja/milho e aveia como planta de cobertura de inverno. O manejo de solo com uma única operação de aração e gradagem, em áreas há vários anos sob sistema de plantio direto, não minimiza o gradiente de fertilidade do solo. Para esse solo com teor de argila acima de 70 %, o gesso foi pouco eficiente em promover a mobilidade vertical de cátions aos 36 meses após sua aplicação, sendo os efeitos limitados aos primeiros 0,10 m de profundidade, diferentemente do observado para o ânion S-SO42-.Escola de Agronomia - Universidade Federal de Goiás2016-01-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/37764Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 45, n. 4, Oct./Dec. 2015; 456-463Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 45, n. 4, out./dez. 2015; 456-463Pesquisa Agropecuária Tropical; v. 45, n. 4, out./dez. 2015; 456-4631983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/37764/20093Basso, Claudir JoséSomavilla, LucindoSilva, Rodorigo Ferreira daSanti, Antônio Luisinfo:eu-repo/semantics/openAccess2020-07-13T16:39:00Zoai:ojs.revistas.ufg.br:article/37764Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:10.054170Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
