Sewage sludge effect on organic matter of soil with plants of Vicia [aha and Sec ale montanum inocoloum with Arbuscular Mycorrhizal fungi

In the recent years use of sewage sludge as a fett ilizer has become prevalent in agricultural lands, because of it is cheap. Sewage sludge is source of nutritional elements. The aims of present study were to Sewage sludge effect on organic matter of soil with plants of Vicia faba and Secale montanum inocoloum with Arbuscular Myconhizal fungi. The experiment was conducted in controlled conditions was completely randomized design and factorile test. Three levels of sewage sludge (0, 100 and 200 tonlha) , two levels of myconhiza (with and without mycorrhiza) and two plant (Secale montanum and Vicia faba) in tln·ee replicated were used. Organic matter content were measured. . The data were analyzed using statistical softwru·e(SPSS). The result showed that as the added sewage sludge is increased , organic matter content is increased both myconhizal plants and control ones, but organic matter was much higher in mycorrhizal plants. As the added sewage sludge in soil that treated by 100 tonlha, organic matter content in plants tissues increased but organic matter in plants tissues were higher in mycoorhizal plants than nonmyconhizal ones.With increase sewage sludge in soil in treated by 200 tonlha, organic matter content in treated soil and plants tissue Secale montanum and Vicia faba are increase. Contents of organic matter were higher colonized plants than control ones
