Like all living things, plants require nutrient elements to grow. The Plant Nutrition Manual describes the principles that determine how plants grow and discusses all the essential elements necessary for successful crop production. The nutritional needs of plants that add color and variety to our visual senses are addressed as well. Altogether, nutritional requirements are given for 143 plants grouped in seven categories from food crop plants to ornamentals. The text begins with an introduction to the basic principles of plant nutrition. Chapters 2 and 3 describe the roles of the major elements and micronutrients. The last two chapters describe techniques for determining the nutrient element status of growing plants through plant analysis and tissue tests. The Plant Nutrition Manual is loaded with information on what plants need for normal vigorous growth and development-free of nutritional stress.
