ABSTRACT
The increasing demand for food globally has been an incentive for the development of various means to raise the agricultural productivity of land. In striving for higher and higher crop yields, fertilizers have made a significant contribution, and the world production of fertilizers has experienced continuous growth. At an early stage, fertilizer production grew rapidly in developed countries. Later, the fertilizer industry gradually developed in countries possessing important resources of raw materials, as well as in countries with large populations where food had a high priority.
