Abstract
For a total of 90 days, two incubation experiments were conducted to study the mineralization of C, N, P and S form clay soil treated by sugarcane residues. The first experiment involved incubating soil samples in incubator at 30 °C to study the emission of CO2 from organic residues, which included determining the amount of mineralized C, and another trail involved incubating soil samples at room temperature to study the other elements using 4 different organic residues [bagasse (B), filter cake (FC), boiler ash (BA), and dry sugarcane leaves (DSL)]. The findings demonstrated that the highest C emission was 232.5 and 225.0 mg C kg-1 of soil treated with B and DSL, respectively, when compared to other organic wastes. The maximum daily C emission for soil amended with B and DSL was 10.7 and 10.2 mg C / kg soil / day, respectively at the 5th day of incubation. N mineralization from all amendments added to the soil showed a decrease at the beginning of the incubation period and then increased with increasing incubation period until the end of the incubation. While P mineralization in the soil amended with the organic wastes used took the same trend as N mineralization. The maximum daily mineralization rate of P was 5.08 mg P kg soil / day on the first day of incubation for the soil treated with BA. Also, S mineralization increases in the first incubation periods, and then decreased with increasing incubation periods in soils treated with all organic wastes.
