Muestras secadas al aire y sin secar de cinco perfiles de Andisoles del norte de la cordillera central colombiana fueron sometidas a extracción con oxalato ácido de amonio y con pirofosfato de sodio. En los extractos de oxalato se determinaron A1, Fe y Si y en los de pirofosfato A1 y Fe. El secado de las muestras redujo significativamente al 95% la cantidad de A1 y de Fe extraída con oxalato ácido, dificultando la clasificación de los suelos en el orden Andisol utilizando los parámetros de la taxonomía del USDA.
