摘要：Eucalyptus grandis plantations established in 1993 and 1996 at Greenacres farm in northern Zimbabwe were irrigated with a
mixture of domestic and pulp and paper mill effluent. Changes in soil pH, electrical conductivity (ECe), soil organic carbon
(SOC), available P (AP), total N (TN), available K (AK), CEC and exchangeable sodium percentage (ESP) were investigated
in the 0-20 and 20-40 cm soil layers of the non-irrigated and irrigated plantations. Irrigation for 12 and 15 years with
hazardous (ECw 2.029 dSm-1, SAR=15.54) effluent mixture significantly (p<0.05) limed (0.95<ΔpH<1.8 units), sodified
