This study was conducted during the 2011-2012 and 2012-2013 seasons in Abu-Jarash orchards area in Damascus to identify the effect of improved organic materials as sludge, manure and compost in improving some soil physical characteristics and wheat productivity. Results showed that the three types of organic material affected the physical characteristics of the studied soil. They decreased its bulk density, increased its total porosity and increased its ability of holding water at field capacity. Results also showed that the compost of city wastes was the best in improving soil physical properties. The three organic materials, particularly the sludge increased the total productivity of wheat (Sham3).
