Resumo: | The objective of this study was to evaluate the adsorption of phosphorus (P) and changes in the concentrations of organic and inorganic forms of P in a Neossolo Quartzarênico (Typic Quartzipsamment) after 9 years of successive cultivation with sugar cane without burning to harvest. Therefore, two areas, one in which cane sugar was planted and a native forest reference area, located in the municipality of Paraipaba-CE, were selected. In each area, samples were collected at depths of 0−0.025, 0.025−0.05, 0.05−0.10, 0.10−0.20, and 0.20−0.30 m, and the levels of organic (Po) and inorganic (Pi) phosphorus obtained by sequential extraction, the remaining phosphorus, and the maximum adsorption capacity of phosphorus by the soil were determined. In general, the permanence of straw on the soil surface under sugarcane cultivation promoted the maintenance of Po levels in the surface layers of the profile. The Po accumulated predominantly in the Po fraction extracted with sodium bicarbonate in both areas. Regarding the Pi content, changes were more evident during cultivation due to the effect of successive phosphate fertilizer applications. The fraction extracted with 0.1 mol L-1 sodium hydroxide was the most representative, with the highest levels of P uptake. P adsorption was influenced by the initial content of the nutrient in the soil and no relationship between P adsorption and organic matter content was observed. The highest level of adsorption was observed in the bottom layer of the forest area (133.3 mg kg-1) and the lowest level of adsorption was observed on the surface layer of the area under sugarcane cultivation (59.5 kg mg-1). |

Para tanto, duas áreas, plantio de cana-de-açúcar e mata nativa de referência, situadas no município de Paraipaba-CE, foram selecionadas. Em cada uma das áreas foram coletadas amostras nas profundidades de 0 – 0,025; 0,025 – 0,05; 0,05 – 0,10; 0,10 – 0,20 e 0,20 – 0,30 m; determinando-se os teores de fósforo orgânico (Po) e inorgânico (Pi) obtidos através de extração sequencial, o fósforo remanescente (Prem) e a capacidade máxima de adsorção de fósforo (CMAP) do solo. De maneira geral, a permanência da palhada na superfície do solo sob cultivo de cana-de-açúcar promoveu a manutenção dos níveis de Po nas camadas superficiais do perfil. O Po acumulou-se predominantemente na fração biodisponível extraído com bicarbonato de sódio nas duas áreas. Com relação ao conteúdo de Pi, as mudanças foram mais evidentes devido ao efeito das sucessivas aplicações de fertilizantes fosfatados ao longo do cultivo, sendo a fração extraída com hidróxido de sódio 0,1 mol L-1, a mais representativa com maiores níveis de P acumulados. A adsorção de P foi influenciada pelo conteúdo inicial do nutriente no solo e nenhuma relação entre adsorção de P e o conteúdo de matéria orgânica foi observada. O maior valor de adsorção de P foi observado na camada inferior da área de mata (133,3 mg kg-1) e a menor adsorção na camada superficial da área sob cultivo de cana (59,5 mg kg-1).Universidade Federal Rural do Semi-Árido2017-01-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/482710.1590/1983-21252017v30n209rcREVISTA CAATINGA; Vol. 30 No. 2 (2017); 343-352Revista Caatinga; v. 30 n. 2 (2017); 343-3521983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/4827/pdfOliveira Filho, José de SouzaPereira, Marcos GervasioAquino, Boanerges Freire deViana, Thales Vinícius de Araújoinfo:eu-repo/semantics/openAccess2023-07-20T10:53:16Zoai:ojs.periodicos.ufersa.edu.br:article/4827Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:19.176705Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
