Pyrolytic characterization of humic acids in relation to carbon sequestration mechanisms in representative soils from the basque country (Northern Spain)

Abstract

Comunicación y póster presentados al citado simposio, celebrado del 17-20 de septiembre, 2002, en Leoben (Austria).Curie-Point analytical pyrolysis was used for the assessment of soil organic matter accumulation processes in representative ecosystems from the Basque Country (Northem Spain). The aim of the study is to identify the main mechanisms of carbon sequestration by carrying out a semiquantitative appraisal of biogeochemical processes ranging from selective preservation of plant macromolecular material to complex processes involving extensive depolymerization of plant-inherited constituents followed by synthesis of humic-type substances.Peer reviewe
