A deficiency of one or more of the eight plant micronutrients (boron, chlorine, copper, iron, manganese, molybdenum, nickel and zinc) will adversely affect both the yield and quality of crops. Micronutrient deficiencies in crops occur in many parts of the world, at various scales (from one to millions of hectares), but differences in soil conditions, climate, crop genotypes and management, result in marked variations in their occurrence. The causes, effects and alleviation of micronutrient deficiencies in crops in: Australia, India, China, Turkey, the Near East, Africa, Europe, South America and the United States of America, are covered, and these are representative of most of the different conditions under which crops are grown anywhere in the world.
Links between low contents of iodine, iron and zinc (human micronutrients) in staple grains and the incidence of human health problems are discussed, together with the ways in which the micronutrient content of food crops can be increased and their bioavailability to humans improved. Detailed treatment of topics, such as: soil types associated with deficiencies, soil testing and plant analysis, field experiments, innovative treatments, micronutrients in the subsoil, nutrient interactions, effects of changing cropping systems, micronutrient budgets and hidden deficiencies in various chapters provides depth to the broad coverage of the book.
This book provides a valuable guide to the requirements of crops for plant micronutrients and the causes, occurrence and treatment of deficiencies. It is essential reading for many agronomy, plant nutrition and agricultural extension professionals.
Provides an up to date account of the incidence of micronutrient deficiencies in countries, regions and continents representative of most of the different conditions under which crops are grown anywhere in the world
Deals with the physiological functions of boron, chlorine, copper, iron, manganese, molybdenum and zinc in higher plants and the effects that deficiencies have on these functions
The links between the contents micronutrients, such as iron and zinc, in crop products and human health are discussed in detail
Covers in detail, micronutrient deficiencies in the world's major staple grains: maize, rice and wheat as well as legumes, vegetable, root, oil and tree crops
Individual chapters cover numerous related topics in considerable detail, including: soil and plant analysis, field experiments, micronutrient fertilisers, trace element budgets, interactions between nutrients, effects of changes in cropping system, and hidden deficiencies
No other book covers the occurrence of deficiencies in a wide range of countries and regions and their respective cropping systems in such detail
