A pot experiment for poplar growth and soil quality with sewage sludge application

Abstract: To study the influence of sewage sludge on poplar (Populus deltoids Lus P. euramericana I-45/51) growth and on soil environmental quality,a greenhouse,pot experiment was conducted with anaerobically digested,dewatered sludge obtained from the Wuxi Lucun Wastewater Treatment Plant in Jiangsu Province. A two factor gradient test design with five treatments (rates of sludge application expressed as sludge to soil ratio) of 0(control),30,60,120,and 240 gkg-1 and two soil types(calcareous soil and yellow brown soil) with 3 replications was established to test height,diameter,biomass,and concentrations of heavy metals,Cu and Zn. Results showed that for calcareous soil,poplar growth was promoted with the 30 gkg-1 sludge treatment,whereas the other treatments all restrained growth;and for yellow brown soil,poplar growth of all treatments were promoted,but 30 gkg-1 sludge treatment was better than the others. In addition,soil total and available N and P as well as organic matter increased(P<0.05). After sewage sludge application,exchangeable Cu and Zn also increased,and there was a positive relationship(r0.05 = 0.811) between sludge ratio and exchangeable metal concentration. Thus,compared with no sewage sludge application,a 3% sludge treatment could promote growth and production of poplar[Ch,1 fig. 4 tab. 15 ref.]
