Resumo: | Inadequate management of irrigated soils results in degradation by salinization and sodicity; therefore, the knowledge of their chemical properties, for the adoption of efficient correction techniques is necessary. Thus, this research aims to identify the variation of the chemical properties of saline soils and verify the effect of sulfuric acid on these attributes and initial growth of algaroba [Prosopis juliflora (SW) DC]. The samples of soil used were collected at the São Gonçalo Irrigated Perimeter and sent to the laboratory for chemical characterization. The correlation between PST and CE, pH, Ca2+ and Mg2+ was studied. In the next step, an experiment was carried out on the Prosopis juliflora species, applying four increasing doses of H2SO4 (0, 2, 4, 6 ml/kg soil), with three replicates. Soils were sampled (100 g vaso-1) for pH determination and extraction of P contents using two extractors: Mehlich-1 and Olsen. The chemical attributes in the irrigated area presented high spatial variability, and the application of H2SO4 doses in the soil provided a reduction of pH and uneven growth of Prosopis juliflora. |

Assim, esta pesquisa visa identificar a variação dos atributos químicos em solos salinizados e verificar o efeito do ácido sulfúrico nesses atributos e no crescimento inicial da algaroba [Prosopis juliflora (SW) D. C.]. As amostras do solo utilizadas foram coletadas no Perímetro Irrigado São Gonçalo (PB) e encaminhadas ao laboratório para a caracterização química. Estudou-se a correlação entre porcentagem de sódio trocável e condutividade elétrica, pH, Ca2+ e Mg2+. Na etapa seguinte, conduziu-se um experimento com a espécie Prosopis juliflora, aplicando-se quatro doses crescentes de ácido sulfúrico (0, 2, 4, 6 mL/kg solo), com três repetições. Os solos foram amostrados (100 g/vaso) para determinar os teores de pH e extrair os teores de fósforo utilizando dois extratores, Mehlich-1 e Olsen. Os atributos químicos na área irrigada apresentam elevada variabilidade espacial e a aplicação das doses de H2SO4 no solo reduziu o pH e o crescimento desuniforme das plantas de Prosopis juliflora.Universidade Federal Rural da Amazônia/UFRA2018-09-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ajaes.ufra.edu.br/index.php/ajaes/article/view/2811Amazonian Journal of Agricultural Sciences Journal of Agricultural and Environmental Sciences; Vol 61 (2018): RCARevista de Ciências Agrárias Amazonian Journal of Agricultural and Environmental Sciences; v. 61 (2018): RCA2177-87601517-591Xreponame:Revista de Ciências Agrárias (Belém.
