2-Reduce the environmental hazardous impacts of organic wastes throughout augmentations by different rates of cheap materials to reduce or replace added fertilizers and their environmental effects as well as saving them economically.
3-Assessment of biophysiochemical characteristics and quality of the different composts.
4-Evaluate the composts effects at different rates,on some chemical,physical and biological properties of used soils and on the post -harvest,quantity and quality of planted yield.
