Se estudian la mineralogia de los compuestos de Fe y la estabilidad de los compuestos magnéticos de tipo espinel en dos suelos de mineralogía y condiciones de manejo del suelo muy diferentes, y bajo la acción de climas y regímenes hídricos muy distintos (Molisoles de Bahía Blanca y Ultisoles de un yerbatal de Misiones) usando la espectroscopía Mossbauer a temperatura ambiente y a 15K. También se realizan mediciones de magnetización y se llevan a cabo las técnicas tradicionales para el estudio de suelos: DRX y los métodos químicos de disolución selectiva. Se hacen sugerencias para la implementación de la espectroscopía Mossbauer al estudio de los suelos pobres en Fe (Molisoles) y se estudia la eficiencia del tratamiento de disolución de Fe D...
