Fungi diversity analysis in different soil managment

Abstract

The understanding of soil life dynamics allows the development of possible solutions regarding
the minimization of the use of external inputs in ecosystems. The use of mineral fertilizers and
chemicals counteracts principles of agroecology, which aims sustainable soil management,
facilitating the completion of the matter cycle, a dynamic that occurs naturally in healthy soils.
The present work aimed to evaluate the population of soil microorganisms (fungi and bacteria)
in different management systems, comparing the biotic factors and how they interfere in the
microbiota, one of the main indicators of soil quality. A biological survey of three soil types was
carried out according to the use: 1-conventional grape planting, 2 agroforestry system (SAF)
and 3-secondary forest. It was found a greater diversity in the conventional planting, but with a
greater dominance of species, unlike the agroforestry system, where the diversity of fungi was
smaller, but with less dominance. These results lead to the conclusion that soil management is
directly related to the complexity and quality of the soil.
