Abstract/Contents:"Sewage sludge from Qilihe Sewage Treatment Factory, Lanzhou, China, were applied to lawn sown by Lolium perenne and effects on the soil environment were measure by using different quantity of sewage sludge in comparison with chemical fertilizer. The results showed that the physical and chemical characters of the soil were improved while the application quantity of sewage sludge was in the range of 0.5~8.0 kg/m2, the contents of total and available N, total and available P, organic matter were increased, bulk density was decreased. While the application quantity of sewage sludge was in the range of 4.0~8.0 kg/m2, the contents of Fe, Cu and Zn were increased, and the contents of Ni, Pb, Cr, As and Hg in soil of 0~20 cm depth had no significant difference compared with that of the control treatment. Heavy metal elements did not move down to the deep layer of soil and cause pollution on the soil."
