چکیده

Plane (Plantanus Spp) is one of the annually deciduous tree that the procedure of it·s leaves composting takes long time. In order to study the effect of additive organic materials on quality and rate of plane tree leaves composting, a green house experiment were conducted using complete randomized design block with 3 replications. The treatments included 0, 25, 50, 75 percent of additive materials (manure, eagle fem( Pteridium aquilinium) andelder(Sambucus eblulus) leaves on volume base. The control was 100% plane tree leaves. This materials were composted in 6 month, and were monthly sampeled and C/N, C/P, pH and Ec parameter were measured. The results showed that the chenges of C/N ratio in plane tree leaves was too low; however the C/N ratio of the additive materials had decreased significantly (P< 0.01 ). Different volume percents of additive materials decreased C/P ratio significantly (P< 0.01).The greatest decline of C/P ratio obse1ved in manure treatments.The value of pH in all treatments ranged from 5.5 to 8 in 6 month. All treatments showed increasing in Ec significantly (P< 0.01) at the end of experiment
