Resumo: Subsurface acidity in Brazilian soils is one of the main factors that cause crop yield reduction and is closely related to high concentrations of Al3 + in depth in the soil. An effective and viable alternative to reduction or elimination of subsurface acidity is to apply gypsum in the soil. In this sense, the objective of this trial was to investigate the effects of gypsum application and time of contact in the soil chemical (Ca, Mg, K, Al, SO42-, pH water e pH CaCl2) and physical (water aggregate stability, MWD, GMD, SAI and micro and macroporosity), assess possible changes in different Al pools (amorphous Al, organic matter bound Al and crystalline Al) and productivity, nutrient uptake (Ca, Mg, K, S, P and N) and agrotechnological variables of sorghum influenced by rates of mineral gypsum. A field test was set up in randomized block design. It was evaluated the application of 0, 2, 4, 6 and 8 t ha-1 of gypsum at three depths (0.0-0.2, 0.2-0.4 and 0.4-0.6 m) in four times [before applying gypsum (0), 15, 64 and 90 days after applying gypsum] to the chemical characteristics of the soil. 5 months after gypsum application soil physical characteristics was evaluated. In plots that received 0, 4 and 8 t ha-1 of gypsum and at 0 and 15 days after application Al forms in the soil were evaluated and was evaluated the effect of gypsum rates in the production, nutrient uptake and agrotechnological characteristics of sorghum. Mineral gypsum application promoted changes in soil chemical characteristics throughout the soil profile (0-0.6 m) by raising the levels of Ca and SO42- and reduced, in the subsoil, Al3+ concentrations and its saturation. It not promoted K+ and Mg2+ leaching and did not promote changes in soil aggregation and stability. Increasing the time of mineral gypsum contact with the soil, greater effect of its performance was observed mainly the rise in exchangeable Ca in subsurface. There was increase of amorphous forms of Al in the subsurface, reduction of forms bounded to organic matter and there was no interference in the crystalline forms of Al in the soil profile. It was observed increase in Ca uptake and reduction in K uptake, besides increasing sorghum productivity. There was no interference in the agrotechnological variables of sweet sorghum.

Uma alternativa eficaz e viável para sua redução é a aplicação de gesso. Nesse sentido, o objetivo desse ensaio foi investigar os efeitos da aplicação e tempo de contato do gesso com o solo em propriedades químicas (Ca, Mg, K, Al, SO42-, pH água e pH CaCl2) e físicas (estabilidade de agregados em água, DMP, DMG, IEA e micro e macroporosidade), verificar possíveis alterações nos diferentes compartimentos de Al do solo (Al amorfo, Al ligado a matéria orgânica e Al cristalino) e produtividade, absorção de nutrientes (Ca, Mg, K, S, P e N) e características agrotecnológicas do sorgo influenciada por doses de gesso mineral. Um ensaio em campo foi montado em delineamento em blocos ao acaso. Avaliou-se a aplicação de 0, 2, 4, 6 e 8 t ha-1 de gesso em três profundidades (0,0-0,2; 0,2-0,4 e 0,4-0,6 m) em quatro períodos [antes da aplicação de gesso (0), 15, 64 e 90 dias após a aplicação do gesso] para as características químicas do solo. Aos 5 meses após a aplicação de gesso as características físicas do solo foram avaliadas. Nas parcelas que receberam 0, 4 e 8 t ha-1 de gesso e aos 0 e 15 dias após a aplicação as formas de Al no solo foram avaliadas e foi avaliado o efeito das doses de gesso na produção, absorção de nutrientes e características agrotecnológicas do sorgo. A aplicação de gesso mineral promoveu alterações nas características químicas do solo em todo o perfil de solo (0-0,6 m) elevando os teores de Ca e SO42- e reduziu, em subsuperfície, os teores de Al3+ e sua saturação. Não promoveu lixiviação de K+ e Mg2+ e não promoveu alteração na agregação do solo e sua estabilidade. Aumentando o tempo de contato do gesso mineral com o solo, maior efeito de sua atuação foi observada, principalmente na elevação dos teores de Ca trocável em subsuperfície. Houve aumento das formas amorfas de Al em subsuperfície, redução das formas ligadas à matéria orgânica e não houve interferência nas formas cristalinas de Al no perfil do solo. Observou-se incremento na absorção de Ca e redução da absorção K, além de aumento da produtividade do sorgo. Não houve interferência nas variáveis agrotecnológicas do sorgo sacarino.Submitted by (lucia.rodrigues@ufrpe.br) on 2016-08-01T12:29:56Z No. of bitstreams: 1 Igor Tenorio Marinho da Rocha.pdf: 1591816 bytes, checksum: 842d5137acaed5a66bed50979e119b8c (MD5)Made available in DSpace on 2016-08-01T12:29:56Z (GMT).
