Abstract

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