This research was done with the aim of valuation of main soil nutrients and emphasize on forest soil in Shimbar conservative forest in Khozestan province. At first, EPM method was applied for determining erosion and then the amount of soil waste of 3 main nutrients including nitrogene, phosphorus, and potassium based on differences of soil nutrients of control and eroded area, then valuation of forest soil nutrients based on replacement method was assessed. The results of present research showed that in study area including 3116ha, 468.5 ton of NPK eroded caused by erosion, that means 88202945491 Rials to environment. On the other hand, the results indicated that the studied forest can prevent eroding NPK equal to 28306465 Rial, that means the high value of canopy cover and forest.
