Abstract:
The study of the chemical fertilizer consumption in different countries provides basal data for the decision-making of fertilizer production and for the environmental impact assessment of fertilizer application. Hence, the aim of this research was to study and compare the trend of the chemical fertilizer consumption from 1980 to 2012 in Iran, Turkey, Japan, Germany, France, and the USA. For this purpose, various indices such as application rates (kg ha-1) of N, P, and K, arable land, and total fertilizer consumption were analysed. Results showed that the application rates of nutrients (N-P2O5-K2O) in Iran, Turkey, Japan, Germany, France, and the USA in 2012 were 100-42-7, 100-42-7, 100-94-60, 100-17-25, 100-13-38, and 100-33-35, respectively. The lowest and highest area under production were observed in Japan with 4.0 million ha (0.033 ha/person) and in the USA with 155.0 million ha (0.51 ha/person) during 2008-2015, respectively. In addition, the highest and lowest application rates of net nutrient consumption were recorded in France and Germany (285 and 285 kg ha-1) and in Iran (66 kg ha-1), respectively. Overall, the average net consumption of fertilizers in the studied countries in three recent decades (million tonnes) decreased in the order: the USA (19.282) > France (4.601) > Germany (3.302) > Turkey (1.825) > Japan (1.604) > Iran (1.130). Regarding an estimated 9.2 billion people by 2050, the balanced consumption of nutrients (N-P2O5-K2O) and the principles of optimal consumption of fertilizers are keys for achieving the increased food production, food security, and environmental conservation.
