| Abstract | ||
| This study aimsat evaluating the impacts of applying different compost types produced in Alexandria city on the soil and plant. Composting is the biological decomposition and stabilization of organic substrates. It isa means of converting objectionable wastes, such as sewage sludge, garbage, organic trash, food processing wastes and farm manures into materials suitable for application to land. Sandy soils and four types of compost with different rates were applied; composted sewage sludge, Composted domestic solid waste, composted plant residues, and composted animal manure. The Tested plantwas Wheat (Giza 75). Pot experiments were carried out at lab.the results revealed that application of different types of compost to sandy soil cultivated with wheat plant increased soil salinity (EC), organic matter (OM), available nitrogen, and trace element (Fe, Mn, Zn, Cu, Cr, and Pb) contents while decreased pH and available phosphorus. As the soil treated with different compost types were enriched with macro and micronutrients, the fresh plants and oven-dried weights of the plants of treated soil were higher than those of plants of untreated control soil. It is clear that sewage sludge and domestic solid wastes composts application indicated a highest plant yield among other compost types.This study recommended Application of sewage sludge compost must be under special control, Application of domestic solid wastes could be used at the rate of 10 and 20% for sandy soil, plant residues compost could be applied on sandy soil, at the rate of 10% only for cultivation of all crops, and Application of animal manure compost could be applied at the range of 20-30% in case of sandy soil for all crops. | ||
