Caracterización físico-química y espectroscópica de suelos de cultivo de Senegal

Abstract

En este trabajo se analizan suelos de cultivo y enmiendas orgánicas provenientes de Senegal, dentro del marco de un proyecto de cooperación. Se han evaluado parámetros de carácter químico (pH, conductividad eléctrica, contenido en CNH, capacidad de intercambio de cationes) y espectroscópico (infrarrojo medio con accesorio ATR y fluorescencia de Rayos X). Los resultados han revelado que los distintos suelos estudiados no presentan las características más idóneas para su uso como tierra de cultivo debido, en especial, a sus bajas cantidades de materia orgánica, inferior al 1% en todos los casos, y de algunos elementos necesarios para el normal desarrollo de los cultivos. Se han encontrado valores de conductividad bajos en los suelos y altos en las enmiendas orgánicas, relaciones C:N inusualmente bajas y poca disponibilidad de algunos elementos como el Fe, el K o el Ca.

In this study, crop soils and organic amendments from Senegal are analyzed within the framework of a cooperation project. Chemical parameters (pH, electrical conductivity, CNH content, cation exchange capacity) and spectroscopic parameters (mid-infrared with ATR accessory and X-ray fluorescence) were evaluated. The results revealed that the different soils studied do not have the most suitable characteristics for use as cropland, primarily due to their low levels of organic matter (less than 1%) and the lack of some elements necessary for normal crop development. Low conductivity values ​​were found in the soils and high values ​​in the organic amendments, with unusually low C:N ratios and low availability of some elements such as Fe, K, and Ca.
