Corn is one of the most important agricultural crops of the world. This chapter examines the more pertinent literature dealing with the field of mineral nutrition and growth of corn, particularly as it relates to various cultural aspects of corn production—probably one of the most comprehensive studies ever published on the accumulation and movement of various organic and inorganic materials in developing corn plant. This work represents the first great forward step in advancing the knowledge of the nutrition of corn. The uptake of nutrients and water by corn roots is influenced by many factors ranging from the rate of growth and location of the roots in the soil to the influence of one ion upon the entry of another. Many interrelationships and interactions exist between the various factors, all of that influence: directly or indirectly, the ability of the corn plant to absorb the nutrients and water essential to its growth. The approximate quantity of each element required, the pattern of its translocation within the plant during growth, and the final effects upon the composition and quality of the crop all have an important bearing in the determination of the nutrient needs of the crop and in developing and evaluating fertilizer and management practices. The corn plant exhibits characteristic symptoms of most of the common nutrient deficiencies. Nitrogen deficiency symptoms are by far the most prevalent and are observed in most localities where corn is grown. Lack of adequate soil moisture is one of the major limiting factors in corn production not only in the arid and subhumid regions but also in the humid eastern states. These include practices involving irrigation, thickness of planting, row spacing, fertilizing, and tilling.
