For studying the effectiveness of agricultural utilization of sewage sludge,soil physical and chemi-cal properties and crop output before and after sewage sludge utilization were studied by the field experiment of sludge utilization. Results showed that along with increased sludge application quantity,the maximum soil bulk density was reduced by 14.8% and the quantity of water stable aggregates amounted to 31.5%.The contents of available Nitrogen and available Phosphor were significantly increased and the content of organic matter was increased simultaneously. The output of wheat and corn increased , sludge application quantity was 56.25t/ hm²,and wheat production increase reached the extremely remarkable level. Corn output was higher than the contrast and increased with the increased quantity of fertilizer
