Abstract
Microorganisms are excellent soil quality indicators because their properties
within the soil community change quickly in response to changes in the surrounding
environment. The aim of this study was to determine if the structure and diversity of
soil bacterial and fungal communities were useful for discriminating cut flower cultures
under conventional (CM), ecological (EM), and intermediate (IM) management practices.
Results obtained by PCR-DGGE revealed that bacteria had lower similarity in structure
and higher diversity under EM than under CM. Sites under IM showed greater similarities
in structure and diversity to the site under CM, although there were still significant
differences between them. Fungal structure showed higher similarity among sites, with
differences in diversity only between EM and CM. In the sites studied, bacteria, rather
than fungi, were good indicators of changes in soil quality. The results of this study
confirmed that EM and IM promote soil bacteria diversity.
