The mission of the International Fertilizer Development Center is to increase food production through the improvement of fertilizers and fertilizer practices for the developing countries with special emphasis on tropical and subtropical agriculture. The principal aim is to ensure that fertilizer technology is not a limiting factor to food production in those regions. Although the full extent to which deficiency of micronutrients hampers food production is yet un known, there is ample evidence that problem areas exist and more will be identified as crop production is intensified and marginal lands are exploited. Therefore, it seems fully appropriate at this time that IFDC, as an international organization, take a leadership role in developing micronutrient fertilizer technology appropriate for the tropics and subtropics. The gravity of micronutrient deficiency as a limiting factor to crop pro duction varies from crop to crop and from soil to soil. The effects may range from slight yield reductions to complete crop failure. While the economic impact of omitting micronutrients in seriously affected areas (e.g., Zn in Brazilian Cerrado) is convincing, it is difficult to estimate the yearly loss in crop production due to unsuspected micronutrient deficiency. Active soil and crop testing programs in regions with advanced agricultural systems are aimed at recognizing micronutrients as a limiting plant nutrient in time to allow corrective measures and prevent yield loss. Successful micronutrient monitoring systems are generally limited to developed economies or to developing economies producing export cash crops.

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.

Micronutrient research has been an important component of the soil fertility and plant nutrition program in Pakistan since the identification of zinc deficiency in rice in 1969. Since then, considerable progress has been made on diagnosis and management of micronutrient nutrition problems in crops. However, now there is growing R&D evidence that micronutrient malnutrition in humans could be addressed through enriching staple food grains with micronutrients. This book presents the latest R&D information on micronutrient problems in crop plants/cropping systems and their corrective measures. The current status, the constraints, and economic benefits of using micronutrient fertilizers for optimizing crop productivity and soil resource sustainability are discussed along with estimating future potential requirement of micronutrient fertilizers to optimize crop productivity, produce quality, and soil resource sustainability. Wide-scale preventable micronutrient deficiencies in human populations originate from micronutrient-deficient soils over which staple cereals and other food crops are grown. This book summarizes R&D information on fertilizer use-based micronutrient biofortification in staple food grains to address "hidden hunger" in human populations. The book also presents the best management practices by which micronutrient deficiencies could be corrected in crop plants in a farmer-friendly manner. Features Reviews the micronutrients R&D carried out in Pakistan over the past five decades Focuses on soil–plant analysis techniques for effective prognosis and diagnosis of micronutrient disorders Presents spatial variability maps of micronutrient deficiencies in agricultural soils and crops Provides value–cost ratios of using micronutrient fertilizers for major crops Works out current use level of micronutrient fertilizers and their potential future requirements in the country Discusses agronomic biofortification approach for enriching crop-based food with micronutrients to address "hidden hunger" Presents a compelling case for enhanced use of the deficient micronutrient fertilizers to optimize crop productivity, farmer income, and national economy Presents micronutrient fertilizer use recommendations for salient crops and discusses fertilizer use for micronutrients in the context of 4R nutrient stewardship Recommends future R&D needed for optimizing micronutrient nutrition of crops

This volume addresses various issues related to micronutrient deficiency, especially zinc, and discusses the possible approaches for combating mineral deficiency among humans and plants. The book mainly focuses on the zinc biofortification of vegetable and cereal crops and highlights the consequences of zinc deficiency and the health risks associated with zinc deficiency, especially in children and expecting mothers. The authors discuss different types of food that are rich in zinc and other minerals, how diets can be designed to meet the daily zinc requirements, and the impact of zinc deficiency on plant health and quality of agricultural products and the role of micronutrients in abiotic stress tolerance. The book also covers sustainable approaches to zinc biofortification in crops, such as the microbial solubilization of zinc in soil to improve zinc uptake by plants, and the formulation of these microbes into biofertilizers. The book will be of interest to dieticians, agricultural scientists, students and microbiologists.
