The impact of mineral fertilizers on an agricultural system has been analyzed. It has been shown that encapsulated fertilizers of prolonged action are the effective type of fertilizers that enable to achieve rich harvests and simultaneously consistently reduce the load on the agricultural system. Balance calculations on evaluating the agricultural system contamination level in case of implementing granulated and encapsulated fertilizers have been carried out. It has been shown that in case of using encapsulated fertilizers instead of granulated fertilizers, the environmental contamination caused by excessive nutrition elements of mineral fertilizers indigested by the plants decreases almost fourfold. Pilot experiments on using such cultures as potato, soy, and maize have proven that the effectiveness of using encapsulated fertilizers in comparison with granulated fertilizers under condition of less expenses of mineral fertilizer is 30–50 % higher.
