ABSTRACT
Glucose and cellulose decomposition and subsequent transformation of sulphur (S) and phosphorus (P) in were examined. S was applied @ 0 and 20 μg as MgSO4.7H2O together with either 3000 μg glucose-C or 3333 μg cellulose-C, 250 μg N, 200 μg P and 250 μg kg -1 soil. Microbial respiration (CO2 evolution), inorganic SO4-S and available P were monitored over 30 days during incubation at room temperature at different intervals of time. Both glucose and cellulose decomposition rates responded positively to the S application. Respiration rate in glucose amended soil was approximately 3 times higher than cellulose. In glucose amended soil, 71 % and in cellulose amended soil, 51 % of the added C was decomposed at the end of the incubation period. Concentration of SO4-S varied significantly during incubation. Mineralization followed by immobilization was observed and maximum net immobilization was 14 and 8 μg S g -1 soil for cellulose plus S20 and glucose plus S2O treatments, respectively. During incubation glucose and cellulose amendment caused immobilization of P.
