Pulp and paper mill waste water irrigation increased pH, EC, organic carbon and exchangeable sodium content of soils. The increase in organic matter content of soils accelerated microbial activity and hence accelerated substrate decomposition with the release of CO 2 . There exhibited a peak followed by a steady‐decline in the rate of CO 2 evolution in effluent irrigated soils. The irrigation of pulp and paper mill combined effluent to soils did not affect microbial activity.
