Application of organic and compost to the newly reclaimed lands maintain ecological balance and develops biological processes to their optimum case. In addition to preservation of soil structure, earthworm, and microorganisms. Addition of composts improves soil chemical and physical properties. It increases the water holding capacity and improve the soil structure and aggregates. Chemical properties include, decrease soil pH, increase cation exchange capacity (CEC) and enhance the availability of the most nutrient which important for plant growth and agricultural production. The intensive use of compost for increasing agricultural production, maintaining and enhancing soil fertility and decreasing pollution hazards is of vital importance especially in the newly reclaimed soil. There are several sources of heavy metals in the environment, both natural and man-made: soil parent material (rocks), commercial fertilizers, liming materials, sewage sludge, animal wastes, pesticides, irrigation waters, coal combustion residues, metal-smelting industries, auto emission, and other.
