Sewage sludge is good known for soil-forming and fertilizing properties due to high concentrations of nutrients available to both plants and soil fauna. The aim of the present experiment was to determine the effect of rates of sewage sludge and NPK fertilizer on the improvement in the properties of nutrient-poor soils. Sewage sludge caused an increase in the concentrations of N, P and K in the soil. Correlation and regression analyses showed significant relationships between total and available forms of N, P and K contained in fertilized soil and plant material
