Quantity, characteristics and composition of organic matter widely vary by changing seasons and geographical conditions. On the other hand when soil conditioning due to poor drainage limits then decomposition of organic matter by soil microorganisms highly reduces. Soil and plant testing is one of the best management methods in measuring these changes. In this study, the effect of seven types of organic fertilizer including Leaf Mold (LM), Rice Husk (RH), manure, Spent Mushroom Compost (SMC), a mixture of LM, RH and manure (mixture 1), a mixture of LM, RH and SMC (mixture 2) with the ratio of 1:1:1 and control (no fertilizer) at three levels of compaction including roller weighted at 36, 56 and 76 kilograms on some nutrient content of sport lawn were investigated in different seasons. An experiment was conducted as a strip plot design in three replications, in research farm of Gorgan University of Agricultural Sciences and Natural Resources during 2008-9. With the comparison of the total mean of leaf nitrogen and potassium in different seasons, the highest and the lowest absorption rate of these elements was observed in the fall and summer respectively. Moreover, statistical analysis indicated higher concentration of phosphorus in spring and summer than fall and winter.
