Abstract
The area of Egypt is about 1 million km2 of which only about 6 million acres are under cultivation, the remaining land ( over 95% of the area ) is barren, desert. Therefore, the most important two factors limiting soil productivity are water and organic matter.
In the old days, Egyptian farmers depended entirely on farmyard manures to supply plant nutrients needed for crop production. The report of environmental quality international (1985 ) show an estimated 11.0000 ton per day municipal solid waste generation rate in Egypt cities. There are a number of aerobic window composting demonstration plants in the 100 to 160 ton per day range operating in six Egyptian cities to produce soil conditioner e.g. Cario, Giza, El-Minia, Zagazig, Dammiatta and Alexandria.
The main objectives of this study are :
1-Transformation of city refuse to organic manure.
2-Improving the fertilizing value of this manure by added nitrogen and phosphorus fertilizers.
3-Assessment the physical, chemical and biological characteristics of the manure.
