Resumo: | Based on the assumption that silicate application can raise soil P availability for crops, the aim of this research was to compare the effect of silicate application on soil P desorption with that of liming, in evaluations based on two extractors and plant growth. The experiment was carried out in randomized blocks with four replications, in a 3 × 3 × 5 factorial design, in which three soil types, three P rates, and four soil acidity correctives were evaluated in 180 experimental plots. Trials were performed in a greenhouse using corn plants in 20-dm3 pots. Three P rates (0, 50 and 150 mg dm-3) were applied in the form of powder triple superphosphate and the soil was incubated for 90 days. After this period, soil samples were collected for routine chemical analysis and P content determination by the extraction methods resin, Mehlich-1 and remaining P. Based on the results, acidity correctives were applied at rates calculated for base saturation increased to 70 %, with subsequent incubation for 60 more days, when P content was determined again. The acidity correctives consisted of: dolomitic lime, steelmaking slag, ladle furnace slag, and wollastonite. Therefore, our results showed that slags raised the soil P content more than lime, suggesting a positive correlation between P and Si in soil. Silicon did not affect the extractor choice since both Mehlich-1 and resin had the same behavior regarding extracted P when silicon was applied to the soil. For all evaluated plant parameters, there was significant interaction between P rates and correctives; highest values were obtained with silicate. |

O delineamento experimental utilizado foi em blocos casualizados, com quatro repetições, em esquema fatorial 3 × 3 × 5, constituído por três solos, três doses de P e quatro corretivos de acidez, além de um tratamento sem correção da acidez, totalizando 180 parcelas experimentais. O experimento foi realizado em casa de vegetação, em vasos de 20 dm3 . Os solos foram submetidos a três doses de P (0, 50 e 150 mg dm-3), tendo como fonte superfosfato triplo em pó e mantidos incubados por 90 dias. Após o período de incubação, foram realizadas amostragens para análise química de rotina e determinações dos teores de P pelos métodos resina, Mehlich-1 e P remanescente. Com base nesses resultados, foi realizada a aplicação dos corretivos de acidez com as doses calculadas a fim de elevar a 70 % o valor de saturação por bases, permanecendo incubados por mais 60 dias; após, novas determinações dos teores de P foram realizadas. Os corretivos de acidez utilizados foram: calcário dolomítico, escória de aciaria, escória forno de panela e wollastonita. A cultura utilizada foi a do milho. Com os resultados, observou-se que as escórias aumentaram os teores de P no solo, quando comparadas ao calcário, sugerindo a interação positiva entre Si e P no solo. O uso do Si não interferiu na escolha do extrator, pois tanto o Mehlich-1 como a resina apresentaram o mesmo comportamento, quando houve a adição de Si ao solo em relação ao P extraído. Para todos os parâmetros analisados na planta, houve interação significativa entre as doses de P e os corretivos utilizados, com maiores valores com o uso de silicatos.Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Universidade Estadual Paulista Júlio de Mesquita Filho (UNESP), Faculdade de Ciências Agronômicas (FCA), Departamento de Solos e Recursos Ambientais, Botucatu, SP, BrasilUniversidade Estadual Paulista Júlio de Mesquita Filho (UNESP), Faculdade de Ciências Agronômicas (FCA), Departamento de Solos e Recursos Ambientais, Botucatu, SP, BrasilUniversidade Estadual Paulista (Unesp)Sandim, Aline da Silva [UNESP]Büll, Leonardo Theodoro [UNESP]Furin, Ariane Reis [UNESP]Lima, Géssica da Silva [UNESP]Garcia, Jader Luis Nantes [UNESP]2016-07-07T12:38:06Z2016-07-07T12:38:06Z2014info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article1215-1222application/pdfhttp://dx.doi.org/10.1590/S0100-06832014000400018Revista Brasileira de Ciência do Solo, v. 38, n. 4, p. 1215-1222, 2014.0100-0683http://hdl.handle.net/11449/14138410.1590/S0100-06832014000400018S0100-06832014000400018S0100-06832014000400018.pdf1090072947808223Currículo Lattesreponame:Repositório Institucional da UNESPinstname:Universidade Estadual Paulista (UNESP)instacron:UNESPengRevista Brasileira de Ciência do Solo0.7990,679info:eu-repo/semantics/openAccess2024-04-30T19:28:16Zoai:repositorio.unesp.br:11449/141384Repositório InstitucionalPUBhttp://repositorio.unesp.br/oai/requestopendoar:29462024-08-05T14:54:47.705740Repositório Institucional da UNESP - Universidade Estadual Paulista (UNESP)false |
