- Abstract
- Conventional parameters (total organic carbon, total nitrogen, humic acids and fulvic acids) frequently
associated with soil quality were measured and compared with the amount and activity of bglucosidases
associated with the humicenzyme complex. Soil quality may be defined as the maintenance
of an enzymatically active humic carbon pool which may express soil resilience and ecological
functions. The combination of ultrafiltration (UF) and isoelectric focussing (IEF) permitted the extraction
and purification of the humic-bound b-glucosidases. Even though humic-b-glucosidases represent only
a small part of soil humic matter either in terms of total soil b-glucosidase activity (321%) or as a proportion
of the humic-C content (48%), they proved to be discriminating parameters (significative differences
at P< 0.05) for defining soil biochemical quality. Specifically, on the basis of the amount of
b-glucosidase activity in the humic fraction >104 Da (IEF peaks in the pH range 3.54.5), the soils were
distributed in a decreasing order of quality: undisturbed meadow > tree plantation > 60-year
vineyard> agricultural soil > 1-year vineyard. (literal)
