Abstract

The objective of this work was to evaluate the effect of cassava cultivation under different management practices on soil microbial biomass, its activity and its derived indexes. The field experiment was carried out in Glória de Dourados, Mato Grosso do Sul State, Brazil, in a sandy soil (Oxisol), under conventional drilling, no-tillage system under Estilozobium pruriens, Sorghum bicolor and Pennisetum glaucum mulching, compared to the native vegetation system. Evaluations were done in May/2003, June/2003, November/2003, April/2004 and November/2004. Soil microbiota was directly influenced by the presence or absence of vegetable residues, indicating that the use of covering plants in cassava cultivation favors the improvement of soil quality, representing a promising alternative for better management practices of this cultivation.
