Abstract

The objective of this study was to characterize the soil fauna and assessing the effects of harvest method and vinasse application in areas of sugar cane compared to a forest area. The experimental design was completely randomized with five treatments (manual harvesting with use of fire and mechanical harvesting without use of fire associate to or not vinasse application fertilizer and forest), five repetitions for six sampling times. Retired monoliths 25 cm x 25 cm x 30 cm, where soil organisms were sorted and classified into groups and /or order. The characterization of the treatments was performed by principal component analysis. Having previously calculated the density of organisms, the ecological indices of diversity (Shannon), evenness (Pielou) and richness of groups, these were compared by Duncan or Kruskal-Wallis test at 5%. Compared with the areas of sugar cane , the forest area has the highest calculated indices. The treatments of sugar cane with maintenance of straw and /or vinasse application favor soil fauna.
