MORELL, F; HERNANDEZ, A; BORGES, Yenia  and  LOPEZ, D. CHARACTERIZATION Agrobiological brown soils FIELD REGION flowers in relation to changes in agricultural management. cultrop [online]. 2010, vol.31, n.4, pp. 00-00. ISSN 0258-5936.

Based on the study of the following soil profiles: calcaric molic Cambisol, calcaric vertic Cambisol and calcaric litic Cambisol, under different managements -from permanent natural conditions until soils with a high degradation as a result of the anthropic influence on agriculture-, a biological characterization was carried out by measuring the indicators of AMF native spore counting, endophyte weight, visual density, infection percentage and glomalin (GRSP) content. A narrow relationship was observed between soil degradation and edaphic mycorrhizal biodiversity; the highest values were recorded in the best preserved soils, with a progressive decrease towards the most degraded ones due to the anthropic influence.

Keywords : Cambisols; glomalin; anthropic influence.
