The Role of Potassium in Agriculture includes contributions by a number of outstanding national and international scientists who have firsthand knowledge of the use of potassium and the indispensable role it plays in modern agriculture. The "from mine to man" arrangement of the book illustrates the role of potassium as a vital element from the time it is extracted from the mine or the brine solution to the time it is consumed in foodstuffs or feed. The authors not only explain how potassium is processed into fertilizer, but they evaluate and compare the different forms of potassium used in today's agricultural industry. Experienced researchers describe the chemical and physical behavior of potassium in the soil and in the plant itself. Other researchers explain the nutritive effects of potassium not only on the more common forage, fruit, vegetable, and field crops of the United States but also on the tropical crops grown in the Southern Hemisphere. Though this book is by no means an exhaustive treatise on the role of potassium in agriculture, the most important facets of potassium technology and use are thoroughly explored. The book is directed to extension workers, farm managers, college and high school teachers, applied research groups, members of the fertilizer industry, teams concerned with the use of potassium in developing countries, and others with specific interests in potassium and its use in fertilizer.
