Abstarct: As most soils are poor of the organic matter content add organic matter in Iran, especially in the form of compost, they are increasing crop yield positive, useful impact on soil physical and chemical properties. Using compost reduces the need to utilize chemical fertilizers of environmental benefits. In order to investigate the effect of municipal solid waste compost fertilizers enriched and un-enriched with chemical fertilizer on some soil chemical and organs of rice, the researcher carried out an experiment as a randomized complete blocks design with three replications and fourteen fertilizer treatment in the research field of Sari University of agricultural Sciences and Natural resources in 2014. Fertilizer treatments included the control (without fertilizer and organic fertilizer), fertilizer treatments (best on the soil test), and treatments of 15, 30 and 45 tons of municipal solid waste compost per hectare as a simple form along with 1/4, 2/4 and 3/4 of chemical fertilizer. The result of analysis of variance showed that application of compost had significant effect on macro element concentration (N, P and K) soil, seed, K leaf and micro element (Fe, Mn, cu and Zn) available soil, leaf and seed rice and treatment of 45 tons of municipal waste compost enriched with 75% chemical fertilizer were 73.68, 230.99, 30.74, 37.25, 16.83, 61.90 and 118% increased rate compared to control treatment had the highest concentration of macro elements (N, P and K) in soil, seed and leaf K. The highest concentration of Fe, Mn and Cu in soil was obtained 45 tons in municipal solid waste compost with 64.62, 51.30 and 142.78% increased rate compared to control treatment. The highest concentration of Zn in soil with 264.3% increase compared to control related to 45 tons of municipal waste compost enriched with 75% chemical fertilizer. Treatment of 45 tons of municipal waste compost with 81.16, 103.3, 48.06, 26, 233.7 and 14.19% increase compared to control have the highest concentration of Mn, Cu and Zn in leaf and seed. Application of 45 tons of compost enriched with 25 and 75% chemical fertilizer showed 70.33 and 87.87% increased rate compared to control treatment the highest concentration of Fe in leaf and seed.
