Temperature and glucose effects on soil organic carbon: co2 evolved and decomposition rate

Abstract

 A study was conducted to determine the effect of glucose on C mineralization from soils with different origins at elevated temperature. Soils from Northern Europe showed higher mineralization rate than Brazilian soils for recent energy source at 35°C. At 15°C as incubation temperature, there was no difference between soils. The addition of glucose to soil accelerated the turnover of native organic C. That acceleration was higher at 35°C and in soils from temperate regions. Only the pH and total soil organic carbon had significant influence on COZ mineralization parameters. No significance was found to C/N ratio and clay content.
