Fire is a management tool for various types of ecosystems, it acts as an important soil mineralization agent. The objective of this study was to compare the effect of burning under the ground in two areas of cultivation. The study setting was a corn crop, consisting of four management systems: soil without revolved not burning (SSQNR) and upturned soil without burning (SSQR); a soil with no upturned burning (SCQNR) and an upturned soil with burning (SCQR). To determine the chemical properties, organic carbon content and soil organic matter, soil samples were collected in depth from 0.0-0.05 and 0.10-0.20 m. There was no interaction between the types of soil management for nutrients K, Al, Ca, Mg, Ca+Mg for relationships, H+Al, MO, CO and Al saturation (m%). As a function of burning, there was significant difference when used the Tukey test at 5% probability relative depth to the organic matter, K, Ca, Mg, Al, Ca+Mg and CO.
