Estimation of Economic Value for Disadvantage of Agricultural Soil

초록

Agriculture soil can contribute adverse effect on ecosystem and total of 4 major adverse effect of agriculturesoil was evaluated for estimating economic value. Soil salinization, soil pollution, soil loss, and greenhousegas production were evaluated. Result showed that total of 20.2 trillion won was estimated and 10.7 trillionwon could be loss due to soil salinization followed by 7.8 trillion won by soil pollution. Soil loss would becost 1.5 trillion won and greenhouse gas emission might cost 1,296 billion won due to methane and nitrogenoxide emission. The highest economic loss was occurred because of over used fertilizer causing soilsalinization followed by soil pollution of heavy metal or pesticide. Overall, reduction of overused fertilizerand best management practice of hazard materials in agricultural field would be the most important factors tominimize disadvantage of agriculture soil.
