Effect of Isfahan polyacryl factory sewage sludge on some of soil quality indices Javad Zamani Babgohari Javadzamany2002@yahoo com Date of Submission 2009 12 09 Department of Soil Science Agriculture College Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi Supervisors M Afyuni afyuni@cc iut ac ir A H Khoshgoftarmanesh amirhkhosh@cc iut ac ir Abstract Application of organic wastes on the agricultural lands as fertilizers enables the recycling of valuable components such as organic matter and many plant nutrients The management and application of organic wastes in agricultural lands decreases environmental risks and increases utilization of these matters The objectives of this study were to evaluate and compare the effect of Polyacril sewage sludge municipal compost and manure on soil quality indices and effect of time on these indices Treatments were sewage sludge of Polyacril factory municipal compost and manure in two rate 15 and 45 ha and control without application of organic waste The experiments were carried out in a randomized complete block design with three replications that include twenty one experimental plots three plots for each treatments one control without sludge and three types of organic waste treatments 6 m long and 6 m wide each were set for the study Organic amendments were incorporated into 0 20 cm depth before planting corn Zea Mays L Soil samples were collected after 31 74 132 and 241 days after application of organic wastes in the lands and corn harvested synchronous with the thrid sampling The results showed that the application of organic wastes improved soil physical properties including bulk density saturated hydraulic conductivity aggregate stability and infiltration rate however application of sewage sludge decreased the saturated soil hydraulic conductivity and water infiltration rate Application of organic wastes also significantly increased electrical conductivity EC soil organic matter and total nitrogen contents as compared to the control Evaluation of biological properties as affected by the application of organic wastes showed that the application of organic wastes significantly increased soil respiration and urease activity Corn yield and yield components were increased significantly by the application of organic wastes Application of organic wastes significantly increased DTPA extractable concentrations of Fe Zn and Cu in soil as compared to the control Keywords Isfahan polyacryl factory sewage sludge Municipal compost Cow manure Soil quality indices Maize Zea Mays L Isfahan
