Hernandez, Z. published the artcileSoil carbon stabilization pathways as reflected by the pyrolytic signature of humic acid in agricultural volcanic soils, Recommanded Product: 2,3,5-Trimethylpyrazine, the main research area is agricultural volcanic soil carbon stabilization humic acid pyrolytic compound.
Mol. assessment of the origin and transformation processes of soil organic matter (SOM) was carried out based on information obtained from 13C NMR and anal. pyrolysis of humic acids (HAs) in soils from wine-growing regions in Tenerife (Canary Islands, Spain). Principal component anal., using as variables pyrolysis products, shows different soil groups defined by the mol. assemblages released from the corresponding HAs, characterized by the predominance of: i) plant biomacromols. (lignin) in soils on pumice substrate, ii) heterocyclic N-compounds and methoxyl-lacking aromatic structures, iii) a substantial domain of alkyl compounds in cultivated soils with active C turnover and finally, iv) polysaccharide and protein-derived compounds in soils developed on amorphous gels. The proportions of the pyrolytic compounds from soil HAs were represented by an upgraded graphical-statistical method (3D Van Krevelen plot) that was used to compare the major SOM structural domains in the different soils. The above results coincide with those suggested by the 13C NMR anal., and were associated to two groups of local land management practices, in terms of their intensity resp. favoring either the transformation of plant-inherited macromol. precursors from vascular plants, or the humification of aliphatic precursors in the presence of specific mineralogical substrates controlling microbial degradation and humification processes.
