Abstract :This study was carried out to determine the effects of rice husk compost insert ignore into journalissuearticles values(RC);, town waste compost insert ignore into journalissuearticles values(TW); and tobacco waste insert ignore into journalissuearticles values(TB); on bicarbonate extractable phosphate content insert ignore into journalissuearticles values(P); in soils having different pH levels under greenhouse conditions. Soil samples used in this study were taken from surfaces insert ignore into journalissuearticles values(0-20 cm); of agricultural fields around Samsun, Northern Anatolia. The experiment was conducted according to split plot design with four doses of organic matterials insert ignore into journalissuearticles values(0, 2.5, 5.0 and 7.5, %);. After a month of mixing organic matterials into soils, lettuce were grown in the medias. According to the results, RC, TW and TB applications into acidic insert ignore into journalissuearticles values(Tepecik);, neutral insert ignore into journalissuearticles values(Kampüs); and alkaline insert ignore into journalissuearticles values(Çetinkaya); soils increased extractable P content. It was observed that effectiveness of organic matterials changed depend on soil reaction, type and dose of organic matterials. All organic wastes were more effective on increment of bicarbonate extractable phosphate content in neutral soil pH when compared the other soil pH levels.
