The main reason for this is high energy consumption of the production process of solid nitrogen fertilizers. While production of liquid nitrogen fertilizers is 30-40% cheaper than manufacturing of complex concentrated water soluble fertilizers. In the agriculture of the United States about 50% of all nitrogen fertilizers are used in liquid form. One of such fertilizer types is ammonia water with ammonia concentration which is 25% min. But using of this liquid nitrogen fertilizer is economically efficient at a short distance from the production plant and manufacturing of liquid nitrogen fertilizers with high nitrogen content is a significant challenge for the chemical industry of Ukraine and the EU.
