SALINIDADE DO SOLO E RISCO DE DESERTIFICAÇÃO NA REGIÃO SEMIÁRIDA

Abstract

Resumen La salinización de los suelos es uno de los problemas que más contribuyen a la degradación de los suelos de las regiones susceptibles a la desertificación. Problema presente en varias partes del mundo incluso en Brasil. En este contexto, el objetivo de este artículo es analizar el proceso de salinización de los suelos en diferentes usos de las tierras en municipios de la Mesorregión del San Francisco (semiárido del Estado de Pernambuco). Pernambucano. Para ello, muestras de suelos recolectadas sobre diversos usos y ocupaciones de las tierras, fueron sometidas a pruebas químicas además de la identificación de la clase de suelo a la que pertenece cada muestra. Los resultados indican que las áreas sobre agricultura irrigada presentan los principales focos de salinización, principalmente en los lugares donde la irrigación es desarrollada a través de agua subterránea. Problema no identificado sobre las muestras recogidas en las caatingas y, parcialmente encontradas sobre las áreas de suelos expuestos y las sometidas a la agricultura temporal. En la región de estudio el manejo agrícola inadecuado es uno de los principales responsables de la salinización de los suelos y los impactos contribuyen a la ampliación de los riesgos a la desertificación local.

Abstract The salinity of the soils is one of the problems that most contribute to the degradation of the soils of the regions susceptible to desertification. This problem is present in many parts of the world, including Brazil. In this context, the objective of this article is to analyze the process of salinity of the soils in different land uses in municipalities of the Mesoregion of São Francisco (semi-arid of the State of Pernambuco). For this, samples of soils collected on diverse uses and occupations of the lands were submitted to chemical tests besides the identification of the class of soil to which each sample belongs. The results indicate that the areas on irrigated agriculture present the main sources of salinity, mainly in the places where the irrigation is performed through underground water. Unidentified problem on the samples collected in the Caatinga and partially found on the areas of exposed soils and those submitted to temporary agriculture (dryland). In the study region, inadequate agricultural management is one of the main responsible for salinity of the soils, and the impacts contribute to the increase of the risks to local desertification.

Resumo A salinização dos solos é um dos problemas que mais contribuem para degradação dos solos das regiões susceptíveis à desertificação. Problema presente em várias partes do mundo inclusive no Brasil. Nesse contexto, o objetivo desse artigo é analisar o processo de salinização dos solos em diferentes usos das terras em municípios da Mesorregião do São Francisco Pernambucano (semiárido do estado de Pernambuco). Para isso, amostras de solos coletadas sobre diversificados usos e ocupações das terras, foram submetidas a testes químicos além da identificação da classe de solo a qual pertence cada amostra. Os resultados indicam que as áreas sobre agricultura irrigada apresentam os principais focos de salinização, principalmente nos locais onde a irrigação é desenvolvida através de água subterrânea. Problema não identificado sobre as amostras coletadas nas caatingas e, parcialmente encontrados sobre as áreas de solos expostos e as submetidas à agricultura temporária (sequeiro). Na região de estudo o manejo agrícola inadequado é um dos principais responsáveis pela salinização dos solos e, os impactos contribuem para ampliação dos riscos à desertificação local.
