Abstract
The present investigation aimed to: 1) maximize utilization of organic materials and municipal organic wastes as well as the cheapest farm residues especially the lignified materials by preparating a matured organic composted materials to improve soil fertility and productivity, 2) reduce the environmental hazard impact of organic wastes throughout mixing their with cheap materials at different mixing ratios as well as reduce or replace mineral fertilizes in order to decrease the pollution as a results of using excessive amount of chemical fertilizers, 3) estimate the biophysicochemical characteristics of the different composted materials to choose the best matured organic composted materials to obtaining material of high quality, 4) Investigate the manuring value of the composted materials by evaluating their effects in different rates on some physical, chemical and biological properties as well as on biomass yield, elemental composition and utilization rates and use efficiencies of some organic and inorganic nutrients in salt affected soils to know the characteristics of the best composted materials of the highest efficiency and also raising the efficiency of others organic materials with special reference to mineral fertilization.
