Arbuscular Micorrizal Fungi and Farm Management Practices
Authorized by Eduardo Jose Azevedo Correa
Arbuscular mycorrhizal fungi (AMF) are commonly
present in most tropical land ecosystems; however, high rates of fertilization
can disrupt their life cycle. The AMF occurrence in different crop systems
compared to native vegetation in tropical conditions is not well understood.
With the aim to analyze potentially benefic symbionts for crop production in an
experimental farm, the AMF community structure along different crop cultivation
was investigated. Soil subsamples were used to inoculate trap cultures using
Sorghum sp. as host. The preserved unfertilized area showed a greater diversity
of AMF, followed by the grassland and sugarcane. Number of AMF spores was also
greater in the preserved area (47 spores per 100g soil) than the numbers
estimated for other sites.
