A field experiment was conducted during 2006 - 2007 and 2007-2008 period  growing seasons at Galbana village of Sahl El-Tina plane east Sueiz canal, Egypt ,which representing a new reclaimed area ,to study effects of organic material and mineral nitrogen rates on some chemical  soil  properties ( EC , pH, cations, anions and available  N, P K , Fe ,Mn, Zn , and Cu contents in saline soil and spinach productivity Results proved that the addition of organic martial and mineral N-fertilizer led to decrease EC and pH values significantly. Increasing of organic material and N –fertilizer additions to soil led to increasing available macro- and micronutrients in soil compared with plots without organic material. The amendment effect on available micronutrients content in soil followed the order, ChM manure > FYM > PRC for Fe, Zn, Cu while for Mn was effect of PRC > ChM > FYM. The organic amendments rates and mineral N-fertilizer led to increase in spinach productivity and its content of macro and micronutrients in leaf The efficient treatments graduated in the orders ChM > PRC > FYM when each  of them  was added at a rate of 10 ton fed.^-1 combined with 40kg urea fed.^-1.
