The lawn has an incredible role in designing and construction of landscape areas and lawn bed provides aeration, moisture and nutrients, which is essential for having an acceptance lawn, so the role of organic matter and degree of soil compactness need to be studied. In the current study, the effect of some bed mixtures including Leaf Mold (LM), Rice Husk (RH), manure, Spent Mushroom Compost (SMC), a mixture of LM, RH and SMC (mixture 1), a mixture of LM, RH and manure (mixture 2) with the ratio of 1:1:1 and control (no fertilizer), also the effect of some different soil compactness (roller weights of 36, 56 and 76 kilograms) on the content of some nutrients of sport lawn in fall season were investigated. Hence, an experiment was conducted at the strip plot design with three replications, in research farm of Gorgan University of Agricultural Sciences and Natural Resources during 2008-09. According to the results of this study, interaction of fertilizer and soil compactness was significant for most measured factors. The manure and control treatments showed the most and the least amount of nitrogen in all compactness treatments respectively. The manure and SMC treatments and also treatments containing these organic matters increased plant phosphorus content in comparing with RH, LM and control treatments. Also in three compactness, manure and SMC treatments showed more plant potassium in contrast to control.
