Abstract
The increasing of population and activities in agriculture and industries in Egypt lead to increase the amounts of residues and wastes, increase the environmental pollution with its hazard to human health. In this study it was tried to minimize the effects of this residues and treat it biologically and chemically. The present investigation aimed to: Evaluate the potential effects of different rates of sewage sludge, chicken and farmyard manures applications with or without difSerent doses of recommended NPK fertilizer, i.e., organic and integrated agriculture, on: yields quantity and quality of corn and sunflower crops under field conditions. The residual impacts of different treatment on soil quality parameters after crop harvest were assessed; and Justify the effect of physical, chemical and photochemical remediation treatments on stabilization and disinfection of three different biosolids as means of waste management using the following assessments: Carry out phytotoxicity trials using pea (Pisum sativum) under greenhouse conditions to assess potential biosolids phytotoxicity on seed germination, seedling growth formation, i.e. nodulation and biological nitrogen fixation (BNF) after remediation treatments of biosolids, disinfection tests for the presence and density of total bacteria and total coliform pathogens in biosolids and mineralization potential of organic nitrogen in biosolids. Experimental work: An field experiment was carried out at El-Ham01 region, Kafr El-Sheikh to evaluate the potential effects of application of sewage sludge, poultry manure and farmyard manure or yield and composition oS some economic crops such as sunflower and corn and their residual effect on soil quality under field condition in crop rotation to emphasize the potentiality of decreasing the applied inorganic fertilizers, as well as sustainability of the environment, and cost reduction of agricultural inputs by recycling these bio-residues. Five levels of each residue biosolid were used (w/w) dry basis, pulverized materials were incorporated into the soil surface (0- 15 cm). Amounts of used amendment were added at one time, mixed with soil before the first crop. Mineral fertilizers were used in three levels of each were added: 0, 50 and 100% of rccwnn-\cndcd amounts.
