Abstract: 
Effects of soil erosion in agricultural production emerge to decreasing form of quality and quantity of crops. Its effects in related to soil are poverty of nutrition and change of soil structure that following of these effects are cost in farm. In this paper, using field information of soil components in seven provinces including: West and East Azarbayjan, Hamedan, Kordestan, Zanjan, Golestan and Kermanshah and apply replacement cost approach, cost of soil erosion are estimated.
Results showed that average annual cost of soil erosion in rainfed wheat lands in 1378-79 is 204411 rials per hectar. With assumption of constant cost for rainfed wheat lands, average annual cost of soil erosion for total rainfed wheat lands (3951 thousand hectar) of Iran is equal 807 bil1ion rials.
With regards to the results, investment on soil conservation practices, attentions to soil sector in policymaking on soil conservation, credit allocation and finally payment of green subsidy as suggestion is introduced.
