Abstract
Two pot experiments were carried out at the Soils Dep.. Faculty of Agriculture, Mansoura Unlven'sty.Dakata Governorate. Egypt , during the wintery growing seasons of ( 2003s 2004 ) . The goals of this study are : 1- expose the pollutant wastes ( sludge ) and optimizing its role in the soil ( especially it is a rich organic waste ) . 2- Increasing the efficiency of some phosphatic fertilizers ( sUper phosphate and rock phosphate ) in the newly reclaimed soil (sandy and calcareous ) using the sludge . elemental sulphur and bio-fertilizers ( phosphoren or mycorhiza ) .
These examend materials were added to the used crop soybean ( Glycine max ) as a single or in combinations . This study was ended to that : it can decrease the phosphorus fixation and increase the phosphorus use efficiency using these materials and the best treatment is that received all those substrates together .
