Soil and Fertilizers: Managing the Environmental Footprint presents strategies to improve soil health by reducing the rate of fertilizer input while maintaining high agronomic yields. It is estimated that fertilizer use supported nearly half of global births in 2008. In a context of potential food insecurity exacerbated by population growth and climate change, the importance of fertilizers in sustaining the agronomic production is clear. However, excessive use of chemical fertilizers poses serious risks both to the environment and to human health. Highlighting a tenfold increase in global fertilizer consumption between 2002 and 2016, the book explains the effects on the quality of soil, water, air and biota from overuse of chemical fertilizers. Written by an interdisciplinary author team, this book presents methods for enhancing the efficiency of fertilizer use and outlines agricultural practices that can reduce the environmental footprint. Features: Includes a thorough literature review on the agronomic and environmental impact of fertilizer, from degradation of ecosystems to the eutrophication of drinking water Devotes specific chapters to enhancing the use efficiency and effectiveness of the fertilizers through improved formulations, time and mode of application, and the use of precision farming technology Reveals geographic variation in fertilizer consumption volume by presenting case studies for specific countries and regions, including India and Africa Discusses the pros and cons of organic vs. chemical fertilizers, innovative technologies including nuclear energy, and the U.N.’s Sustainable Development Goals Part of the Advances in Soil Sciences series, this solutions-focused volume will appeal to soil scientists, environmental scientists and agricultural engineers.

The study of soils today has taken on increased importance because a rapidly expanding population is placing demands on the soil never before experienced. This has led to an increase in land degradation. Land degradation is one of the most severe problems facing mankind. Volume 11 of Advances in Soil Science was devoted entirely to this critical area of soil science. From the beginning of agriculture until about 1950, increased food production came almost entirely from expanding the cropland base. Since 1950, however, the yield per unit of land area for major crops has increased dramatically. Much of the increase in yields was because of increased inputs of energy. Between 1950 and 1985, the farm tractor fleet quadrupled, world irrigated area tripled, and use of fertilizer increased ninefold. Between 1950 and 1985, the total energy used in world agriculture increased 6. 9 times. Until recently, sustainability was seldom, if ever, mentioned in agricultural literature. Now, it is one of the most widely used terms. The high costs ofirriga tion development, escalating energy costs during the 1970s, public concern over potential negative impacts of fertilizer and pesticides on water supplies, soil ero sion, soil compaction and salinity problems, and other concerns have caused many people to question whether many of the present agriculture systems can be sustained. As a result, soil science is beginning to focus more on sustaining the resource base.

In the current scenario, marked by a continual improvement in living standards, it becomes imperative to boost the productivity as well as the efficiency of agriculture, especially horticulture, which holds the potential for significant economic prosperity aligning with Sustainable Development Goal number 8, "Decent Work and Economic Growth". Modern technological interventions, such as geospatial technology and geographic information system (GIS) technology, can be harnessed to yield effective results in addressing challenges and providing enhanced decision support, particularly in the planning of horticultural resource management. Cultivation and production of fresh produce face several challenges, including prolonged juvenile phases and reproductive cycles with extended breeding periods, creating bottlenecks in the process. The evolving trends in biotechnology offer promising solutions for improving the selection of desirable traits. Biotechnological techniques aimed at improving fruit efficiency encompass tissue culture, induction of genetic variability, germplasm conservation, and molecular breeding/genomics. These methods involve the study of genetic diversity, DNA fingerprinting, and Quantitative Trait Loci (QTL) analysis for marker-assisted selection. Over the past few decades, the global population has consistently risen, raising concerns about the ability of the current food system to adequately feed the anticipated 10 billion people in the next 30 years. While this challenge is deemed achievable, certain changes in both food production and consumption systems are essential to ensure sustainability, reduce food loss and waste, and contribute to a global shift toward healthier and more sustainable diets. Implementing sustainable models of crop production represents a significant undertaking. To address the growing food demand amid deteriorating production environments, there is a need for promising technologies and effective management options to enhance productivity. This book is poised to be a valuable resource for horticultural scientists operating in universities, government agencies, and research centers, offering insights into achieving sustainable cultivation practices for fruits. It stands out as the first of its kind, providing in‐depth knowledge on environmentally friendly methods for cultivating temperate fruit crops, to reduce harmful emissions and pollution. This book will delve into the application of geographic information system (GIS) for estimating horticulture area expansion and crop yield. Additionally, it will encompass recent biotechnological interventions in horticulture, circular agriculture models, and emerging non‐thermal food preservation techniques as significant components. Features: Aims to provide a comprehensive and integrated overview of current techno-statistical techniques employed in horticulture, delving into the associated livelihood benefits derived from the practice. Explores the novel geographical trends to identify the site suitability indices of several temperate fruits. Offers a comprehensive and integrated exploration of recent trends in biotechnological approaches aimed at enhancing food production, quality, and safety.

Physiological plant ecology is primarily concerned with the function and performance of plants in their environment. Within this broad focus, attempts are made on one hand to understand the underlying physiological, biochemical and molecular attributes of plants with respect to performance under the constraints imposed by the environment. On the other hand physiological ecology is also concerned with a more synthetic view which attempts to under stand the distribution and success of plants measured in terms of the factors that promote long-term survival and reproduction in the environment. These concerns are not mutually exclusive but rather represent a continuum of research approaches. Osmond et al. (1980) have elegantly pointed this out in a space-time scale showing that the concerns of physiological ecology range from biochemical and organelle-scale events with time constants of a second or minutes to succession and evolutionary-scale events involving communities and ecosystems and thousands, if not millions, of years. The focus of physiological ecology is typically at the single leaf or root system level extending up to the whole plant. The time scale is on the order of minutes to a year. The activities of individual physiological ecologists extend in one direction or the other, but few if any are directly concerned with the whole space-time scale. In their work, however, they must be cognizant both of the underlying mechanisms as well as the consequences to ecological and evolutionary processes.
