The treatments included areas previously burned, areas with mechanical harvesting and no
burning and native forest. Soil samples were collected immediately after the sugarcane harvest from the
treatments at a depth of 0–20 cm. The parameters evaluated were: microbial biomass C and N (MB-C and
MB-N), total organic C (TOC), recalcitrant C (R-C), labile-C (L-C), total nitrogen (TN), pH, exchangeable
cations (Ca2 + + Mg2 + and K+), exchangeable (Al3+) and potential (H+ + Al3+) acidity, and P available in the
soil. Soil chemical fertility under the sugarcane without burning was better than under sugarcane with
burn.
