Soil macrofauna organisms are
recognized as ecological indicators of soil
management practices. Sugarcane monoculture can
produce negative impacts on soil, including
biodiversity loss, which should be evaluated. In that
sense, the aim of this study is to determine soil
macrofauna evolution and diversity under sugarcane
(Saccharum officinarum L.) annual growth cycle
(2012-2013). The study areas are located at Usina
Itajubara in Coelho Neto municipality, in Maranhão
State (Brazil). Soil macrofauna samples were
collected in January of 2015. In order to collect soil
macrofauna samples, 5 pitfall traps were placed in
the field for 7 days. Descriptive statistics and
biodiversity indices were used to carry out data
analysis. Sugarcane harvest with straw burning
initially promoted soil macrofauna taxa better
adapted to system drastic changes. Moreover, as
sugarcane growth year went by, soil macrofauna
biodiversity indices similar to those reported at
natural vegetation areas (Sandbank and Atlantic
Forest) were observed.
