Determination of the coefficient of apparent utilization of nitrogen of the sewage sludge and city waste compost added to the calcareous soil planted with wheat (sham 3)

Abstract

This study was carried out in order to determine the coefficient of apparent utilization of nitrogen of the sewage sludge and city waste compost added to the calcareous soil planted with wheat at the Faculty of Agriculture in Aby Jarash in pot experiment. 

Randomly Complete Block design has been used with three replicates for each treatment then the soil was characterized by determining their physical and chemical properties, as well as sewage sludge and city waste compost by identifying some of its chemical and fertility properties. The coefficient of apparent utilization of nitrogen was determined in the sewage sludge and city waste compost in the presence of wheat crop.

 The results showed that there were differences significant between the sewage sludge treatment compared to city waste compost treatment in the rate of utilization nitrogen. The sewage sludge has exceeded in the mineralization of nitrogen compered to city waste compost which the rates of utilization coefficient sewage sludge and city waste compost were 60.50%, 51.51% respectively.
