Agroforestry systems and other land use systems: prospecting of microrganisms under Amazonian soil

Abstract

Microrganisms in the soil act in their capacity and training process, and the export of nutrients
culture and management of chemical factors the fastest ways to cause loss of microbiota and
imbalance of the population. This study aimed to evaluate the density and diversity of fungi in
three land use systems, located in the municipality of Belterra, Pará. Were collected in each
area three samples composed of 10 sub-samples. We used the method of serial dilution to
isolate the fungus. The density evaluation was made by counting the total number of fungal colonies
and diversity by counting the number of different colonies. The higher density occurred
in the multistrata SAF soil. The areas not differ with respect to diversity. The identified genera
were Aspergillus, Penicillium,Trichoderma and Rhizopus.
