Estudio de los ácidos húmicos y fúlvicos extraidos de un podsol. I. Características analíticas

Abstract

[ES]: En el presente trabajo se estudian las características de ácidos húmicos y fúlvicos extraídos de un podsol con tres agentes extractores distintos. Las diferencias encontradas son mínimas, por lo que se recomienda el empleo en estos suelos de cualquiera de los agentes empleados. La hidrólisis ácida afecta grandemente a los ácidos fúlvicos, pues se produce una pérdida del 80 por 100 del material, por lo que su empleo no es recomendable en esta fracción de las sustancias húmicas. Por el contrario, en los ácidos húmicos, la pérdida no es tan acusada y las características de éstos no cambian en la hidrólisis. Sin embargo, es necesaria una mayor investigación antes de aconsejar el empleo generalizado de este tratamiento.

[EN]: In the present paper the analytical characteristics of humic and fulvic acids isolated by three different extractants from a podzol are studied. The differences found are minimal and the use of any of the three agents are recommended in this soil type. The acid hydrolysis affect in a great extent to the fulvic acids, there is a loss of 80% of the material, being this treatment not recommended in this fraction of the humic substances. On the contrary in the humic acids the loss is not so marked and there are no changes in the analytical characteristics on hydrolysis. However further researchs are necessary before an extensive application of this method.
