| description | The present research had as objective to evaluate the effect of the traditional forest fire and the enleirament of organic residues in attributes biological in soil under caatinga. Four areas of caatinga of 1 ha been selected, to know: (a) the area that were deforested, forest fire and planted with maize and beans, after five years of pousio (CQ); b) area that was deforested and the placed organic residues in leiras and planted with maize and beans between the leiras, after five years of pousio (CL); c) area with 5 years of pousio (P5); d) secondary forest established 50 years (Mata). They had been collected, in these areas, soil samples in the layers of 0 - 20 cm composed of twenty subamostras in March of 2006. The following attributes was evaluated in microbiana biomass carbon (CBM), microbial basal respiration (C-CO2), microbial metabolic quotient (q Co2) and relation CBM:COT (qMIC). In adition, was evaluated the total organic carbon (COT) and some attributes quimic of soil. The highest values of CBM and relation CBM:COT had been found in Mata, P5 and CL, while of COT they had been registered in Mata, CQ and P5. The highest values of C-CO2 release had been observed in CQ and NF, followed of CL and P5. The qCO2 rate was higher in the CQ, comparison to the too much treatments that they had not differed between itself. The multivaried analysis was an important auxiliary tool fos suggesting CBM as an attribute to discriminate the studied areas. |
