Book Description
Plants require essential nutrients (macronutrients and micronutrients) for normal functioning. Sufficiency range is the levels of nutrients necessary to meet the plant’s needs for optimal growth. This range depends on individual plant species and the particular nutrient. Nutrient levels outside of a plant’s sufficiency range cause overall crop growth and health to decline, due either to deficiency or toxicity from over-accumulation. Apart from micronutrients (B, Cl, Mn, Fe, Zn, Cu and Mo), Aluminum (Al), cerium (Ce), cobalt (Co), iodine (I), lanthanum (La), sodium (Na), selenium (Se), silicon (Si), titanium (Ti), and vanadium (V) are emerging as novel biostimulants that may enhance crop productivity and nutritional quality. These beneficial elements are not "essential" but when supplied at low dosages, they augment plant growth, development, and yield by stimulating specific molecular, biochemical, and physiological pathways in responses to challenging environments. The book is the first reference volume that approaches plant micronutrient management with the latest biotechnological and omics tools. Expertly curated chapters highlight working solutions as well as open problems and future challenges in plant micronutrient deficiency or toxicity. We believe this book will introduce readers to state-of-the-art developments and research trends in this field.

Book Description
Large-scale chemical fertilizer application causes irreparable damage to soil structure, mineral cycles, soil microbial flora, plants, and other food chains across ecosystems, culminating in heritable mutations in future generations of consumers. A better way forward is the use of nanofertilizers to focus on macro elements (N, P, K), as switching to nanofertilizers may result in large environmental benefits by replacing the majority of these nutrients. Furthermore, the biosynthesis of nanomaterials using bacteria, algae, yeast, fungus, actinomycetes, and plants has opened up a new avenue of research in the production of inorganic nanoparticles as ecologically friendly fertilizers. Nanofertilizers should also attain increased efficiency because of a several-fold increase in the surface-to-volume ratio of nano-forms of nutrients and their suitability for foliar application, where environmental losses are further reduced. Nanostructured fertilizers can also improve nutrient use efficiency through strategies such as targeted distribution and progressive or controlled-release as they can precisely release their active molecules in response to environmental cues and biological demands. Recent research shows nanofertilizers can increase agricultural productivity by speeding up seed germination, seedling growth, photosynthetic activity, nitrogen metabolism, and carbohydrate and protein synthesis. The potential agricultural benefits of nanofertilizers, their modes of action, and the fate of nanomaterials in soil are all discussed in this book. It also covers nanofertilizer formulation and delivery, applications, uptake, translocation, and their fate in plants, as well as their impact on plant physiology and metabolism. Nutrient nanoformulation is a valuable method that has the potential to alter the agricultural sector and provide solutions to current and future concerns for sustainable and climate-sensitive crops

Book Description
Changes in natural ecosystems can affect biodiversity on a global scale, which in turn affects global food production. Climate change develops under different environmental conditions such as high CO2 concentration, ultraviolet radiation, temperature, salinity, rainfall intensity, etc., causing an increase in the growth of new weeds and pathogens. All these factors alone and in complex can reduce growth, complicate photosynthesis, and reduce the physiological and biochemical responses of plants. On the other hand, studies in recent years have shown that the development of a dual strategy of breeding for stress tolerance and introducing stress tolerant plants into production systems to increase their resistance to various stresses is particularly relevant today. Therefore, research related to physiological, biochemical and molecular responses of plants is of paramount importance to authorize the effects of climate-induced stresses and the likely mechanisms of resistance and/or factors mitigating these stresses in crop plants. Climate change is a dynamic, multifaceted system of modifications to environmental conditions that include abiotic and biotic factors in the world. Therefore, rapid development of studies on the integration between physiological, biochemical and molecular responses that can admit a systems analysis of plants is important, and knowledge of molecular mechanisms will provide breeding programs with relevance to obtaining cultivars tolerant to abiotic stresses with increased productivity. Under this research topic, reviews, new methods and scientific articles will be selected for publication based on applications to agriculture under climate change. This research topic will cover the following themes: - Adaptive capacity of plants to withstand climate change - The role of biodiversity in sustainable agriculture - Manipulation of microclimate for plant productivity - Role of plant extracts in plant stress mitigation - Phytoremediation and bioremediation factors for crop improvement - Perspective of underutilized crops under climate change - Contribution of plant secondary metabolism to stress tolerance - Plant tissue culture and crop improvement - The role of nanotechnology for climate-resilient agriculture - Pre-breeding and germplasm characterization for the development of agronomically relevant crop traits

Book Description
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.

Book Description
This volume is the newest release in the authoritative series issued by the National Academy of Sciences on dietary reference intakes (DRIs). This series provides recommended intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for individuals based on age and gender. In addition, a new reference intake, the Tolerable Upper Intake Level (UL), has also been established to assist an individual in knowing how much is "too much" of a nutrient. Based on the Institute of Medicine's review of the scientific literature regarding dietary micronutrients, recommendations have been formulated regarding vitamins A and K, iron, iodine, chromium, copper, manganese, molybdenum, zinc, and other potentially beneficial trace elements such as boron to determine the roles, if any, they play in health. The book also: Reviews selected components of food that may influence the bioavailability of these compounds. Develops estimates of dietary intake of these compounds that are compatible with good nutrition throughout the life span and that may decrease risk of chronic disease where data indicate they play a role. Determines Tolerable Upper Intake levels for each nutrient reviewed where adequate scientific data are available in specific population subgroups. Identifies research needed to improve knowledge of the role of these micronutrients in human health. This book will be important to professionals in nutrition research and education.
