This book is concerned with the ways in which crops might be developed, or improved, for soils that are agriculturally unproductive because of excesses- high salinity and metal toxicity - and/or deficiencies of certain minerals. The aim is that those working to derive crops for growth on these problem soils should be aware of the many diverse avenues that areavailable. The methods discussed are conventional breeding, selection based on knowledge of the physiological basis of tolerance, the use of cell culture and cytogenetics, and the exploitation of native flora.

This text presents the principles of mineral nutrition in the light of current advances. For this second edition more emphasis has been placed on root water relations and functions of micronutrients as well as external and internal factors on root growth and the root-soil interface.

Written by an international team of experts, this book provides researchers with a better understanding of the major physiological and molecular mechanisms facilitating plant tolerance to adverse environmental factors. This new edition of Plant Stress Physiology is an essential resource for researchers and students of ecology, plant biology, agriculture, agronomy and plant breeding.

Plants are subjected to a variety of abiotic stresses such as drought, temperature, salinity, air pollution, heavy metals, UV radiations, etc. To survive under these harsh conditions plants are equipped with different resistance mechanisms which vary from species to species. Due to the environmental fluctuations agricultural and horticultural crops are often exposed to different environmental stresses leading to decreased yield and problems in the growth and development of the crops. Drought stress has been found to decrease the yield to an alarming rate of some important crops throughout the globe. During last few decades, lots of physiological and molecular works have been conducted under water stress in crop plants. Water Stress and Crop Plants: A Sustainable Approach presents an up-to-date in-depth coverage of drought and flooding stress in plants, including the types, causes and consequences on plant growth and development. It discusses the physiobiochemical, molecular and omic approaches, and responses of crop plants towards water stress. Topics include nutritional stress, oxidative stress, hormonal regulation, transgenic approaches, mitigation of water stress, approaches to sustainability, and modern tools and techniques to alleviate the water stress on crop yields. This practical book offers pragmatic guidance for scientists and researchers in plant biology, and agribusinesses and biotechnology companies dealing with agronomy and environment, to mitigate the negative effects of stress and improve yield under stress. The broad coverage also makes this a valuable guide enabling students to understand the physiological, biochemical, and molecular mechanisms of environmental stress in plants.

Crops as Enhancers of Nutrient Use examines the various plant and soil factors that contribute to nutrient use efficiency of plants. It attempts to address policies regarding Low Input Sustainable Agriculture (LISA), conservation-oriented cropping systems, and reductions in environmental contaminants. It also presents longer-term remedies to some of the inherent problems of high volume applications of expensive fertilizer nutrients. This book emphasizes plant-soil interaction, particularly, nutritional interactions involving rhizosphere, microbes, and stress on the root system. Stress factors include moisture and low and high pH. The book also covers the genetic and physiological response of plant to nutrients at the cellular level, on a whole-plant basis, and when subjected to stress. This book will contribute to the development of a more cost-effective and judicious nutrient usage of major crops.

World population is growing at an alarming rate and is anticipated to reach about six billion by the end of year 2050. On the other hand, agricultural productivity is not increasing at a required rate to keep up with the food demand. The reasons for this are water shortages, depleting soil fertility and mainly various abiotic stresses. The fast pace at which developments and novel findings that are recently taking place in the cutting edge areas of molecular biology and basic genetics, have reinforced and augmented the efficiency of science outputs in dealing with plant abiotic stresses. In depth understanding of the stresses and their effects on plants is of paramount importance to evolve effective strategies to counter them. This book is broadly dived into sections on the stresses, their mechanisms and tolerance, genetics and adaptation, and focuses on the mechanic aspects in addition to touching some adaptation features. The chief objective of the book hence is to deliver state of the art information for comprehending the nature of abiotic stress in plants. We attempted here to present a judicious mixture of outlooks in order to interest workers in all areas of plant sciences.

Abiotic Stress and Legumes: Tolerance and Management is the first book to focus on the ability of legume plants to adapt effectively to environmental challenges. Using the -omic approach, this book takes a targeted approach to understanding the methods and means of ensuring survival and maximizing the productivity of the legume plant by improving tolerance to environmental /abiotic stress factors including drought, temperature change, and other challenges. The book presents a comprehensive overview of the progress that has been made in identifying means of managing abiotic stress effects, specifically in legumes, including the development of several varieties which exhibit tolerance through high yield using transcriptomic, proteomic, metabolomic and ionomic approaches. Further, exogenous application of various stimulants such as plant hormones, nutrients, sugars, and polyamines has emerged as an alternative strategy to improve productivity under these environmental challenges. Abiotic Stress and Legumes: Tolerance and Management examines these emerging strategies and serves as an important resource for researchers, academicians and scientists, enhancing their knowledge and aiding further research. - Explores the progress made in managing abiotic stress, specifically with high yield legumes - Highlights the molecular mechanisms related to acclimation - Presents proven strategies and emerging approaches to guide additional research

This book covers many facets of plant selenium (Se) accumulation: molecular genetics, biochemistry, physiology, and ecological and evolutionary aspects. Broader impacts and applications of plant Se accumulation also receive attention. Plant Se accumulation is very relevant for environmental and human health. Selenium is both essential at low levels and toxic at high levels, and both Se deficiency and toxicity are problems worldwide. Selenium can positively affect crop productivity and nutritional value. Plants may also be used to clean up excess environmental Se. Selenium in plants has profound ecological impact, and likely contributes to Se movement in ecosystems and global Se cycling.

Dokuchaev carried out most of his research in Ukraine. His student and friend, Volodymyr Vernadsky, went on to create trans-disciplinary environmental sciences and the concept of Earth as a living organism, famously taken up by James Lovelock. That spring of ideas still flows and the researches captured in this volume are relevant to present-day problems, and not only in Ukraine. Soils have always been under stress but, in the Anthropocene, mankind is in the driving seat. As a sequel to Soil Science Working for a Living: Applications of soil science to present-day problems, we consider issues of policy as well as soil genesis, attributes and functions in various environments, natural and man-made. We consider human impacts on the soil cover through its use and misuse, highlight methods of research and assessment of soil quality, and the threats of soil degradation. The distinguished contributors also describe and propose various options for evaluation and remediation of degraded soils, drawing on the latest methods of modelling and cartography as well as long-term field experiments and long experience. The book will be invaluable to researchers and practitioners in soil science including graduate and post-graduate education, academics and professionals.
