Effect of brewery sludge amendments on some chemical properties of acid soil in pot experiments.
A laboratory experiment was performed for an incubation period of 120 days in order to evaluate the changes in chemical properties of an acid soil amended with 0, 15, 30, 60 and 120 t ha-' of brewery sludge (BS). Increasing BS rates and incubation time reduced pH of the soil by 0.3-0.5 unit with respect to the control while soluble salts increased from 0.11 to 0.80 dS m(-1). Organic C, exchangeable cations, soluble cations and anions, NH4+-N and NO3--N contents of the amended soil increased as BS rates increased. In addition, BS application caused a slight increase in cation exchange capacity (CEC) and a slight decrease in exchangeable acidity.
