A comparative rate of decomposition of spent wash (a distillery waste) and farmyard manure (FYM) in soil was studied under laboratory conditions. The total quantity of CO2 evolved from spent wash amended soil was nearly three times that from FYM treatment. The rate of decomposition of spent wash and FYM followed first order kinetics during initial period of incubation. The rate in case of spent wash (k=32.57 × 10−3min−1) was approximately 4 times faster than that of FYM (k=8.18 × 10−3 min−1).
