In Brazil, organic citriculture promoters are trying to develop production
systems with higher soil microbial activity and, therefore, with a higher potential for natural
control of pests and diseases. Little is known, however, about the influence of management on the
soil microbiota in citrus orchards. Aspects of soil microbial activity and arbuscular mycorrhizal
fungal diversity were studied in two agroecosystems of orange in Sao Paulo, Brazil, one under
conventional and the other under organic management. The soil in the organic system showed higher
microbial biomass carbon, respiration and metabolic quotient (respiration/biomass) than the soil
in the conventional system. With respect to cellulase activity, there was no difference between
the two systems. The AMF richness and diversity were higher under organic management. |
