The effect of different kinds of organic Fertilizers Addition on microorganisms in chooesed Soil from beach region

In field's experiment had been done in the Tartus governorate during the growing season (2013-2012) Different rates of organic fertilizers were used, the experimental transactions were (10) treatments, control (without fertilization) sheep wastes(10-20-30)tn/h, cow wastes(10-20-30)tn/h, poultry wastes(10-20-30)tn/h. This study aimed to know the effect of adding these fertilizers on biological properties of the soil (the number of physiological groups of microorganisms, and soil respiration). The Results showed increasing in the number of Hertotrophic bacteria , Actenomycetes in the soils which were fertilized in poultry wastes(20),(30)tn/h, and increasing in the number of(bacteria, using mineral from nitrogen, and decomposed of celluose micro organisms) in the soils which were fertilized in poultry wastes(30)tn/h and cow wastes(30)tn/h. As for fertilization, The Results showed decreasing pH in the soils which were fertilized cow wastes(30)tn/h, while soil contents of available P and K and organic mater increased in soil which were treated fertilized in poultry wastes(20),(30)tn/ h, and cow wastes(30)tn/h.
