Micronutrients in Agriculture

As yield potentials increase, micronutrient nutrition, especially interactions with other elements, should become more important. Particular attention must be paid to effects of genetic diversity on micronutrient nutrition. The availability of the essential micronutrients boron, copper, iron, manganese, molybdenum, and zinc to plants is often poorly related to the total quantity of the particular element in the soil. Soil properties such as pH, redox potential, organic matter content, nutrient interactions, the type of plant or variety, and environmental factors, such as soil water content, temperature and light, greatly influence the likelihood that a plant will exhibit micronutrient-deficiency or -toxicity symptoms. This chapter examines the specific effects of environmental factors on the solubility of the micronutrients in soil. It then discusses the influence of parent material, pH, organic matter, redox potential, and nutrient interactions on soil micronutrient availability. © 1991 Soil Science Society of America.
