Book Description
Plant nutrients are found in a relatively thin layer of soil materials that covers all of the continents of the entire world. These plant nutrients provide the necessary food, clothing, and shelter for human existence. As the population of the world increases, the plant nutrients in desert environments become more and more important for the survival of mankind. Plant Nutrients in Desert Environments is a general information book for both professionals and laymen. The common plant nutrients present in deserts are identified, and detailed instructions are given on how to effectively utilize them in commercial agriculture, home gardening, home landscaping, for disturbed land reclamation and for recreational purposes. Outstanding photographs illustrate the topics.

Book Description
"Food Plants of the Sanoran Desert includes not only plants such as gourds and legumes but also unexpected food sources such as palms, lilies, and cattails, all of which have provided nutrition to desert peoples. Each species entry lists recorded names and describes indigenous uses, which often include nonfood therapeutic and commodity applications. The agave, for example, is cited for its use as food and for alcoholic and nonalcoholic beverages, syrup, fiber, cordage, clothing, sandals, nets, blankets, lances, fire hearths, musical instruments, hedgerows, soap, and medicine, and for ceremonial purposes. The agave entry includes information on harvesting, roasting, and consumption - and on distinguishing between edible and inedible varieties.".

Book Description
Nearly one-third of the land area on our planet is classified as arid or desert. Therefore, an understanding of the dynamics of such arid ecosystems is essential to managing those systems in a way that sustains human populations. This second edition of Ecology of Desert Systems provides a clear, extensive guide to the complex interactions involved in these areas. This book details the relationships between abiotic and biotic environments of desert ecosystems, demonstrating to readers how these interactions drive ecological processes. These include plant growth and animal reproductive success, the spatial and temporal distribution of vegetation and animals, and the influence of invasive species and anthropogenic climate change specific to arid systems. Drawing on the extensive experience of its expert authors, Ecology of Desert Systems is an essential guide to arid ecosystems for students looking for an overview of the field, researchers keen to learn how their work fits in to the overall picture, and those involved with environmental management of desert areas. - Highlights the complexity of global desert systems in a clear, concise way - Reviews the most current issues facing researchers in the field, including the spread of invasive species due to globalized trade, the impact of industrial mining, and climate change - Updated and extended to include information on invasive species management, industrial mining impacts, and the current and future role of climate change in desert systems

Book Description
This book offers a concise but comprehensive introduction to desert ecology and adopts a strong evolutionary focus. As with other titles in the Biology of Habitats Series, the emphasis in the book is on the organisms that dominate this harsh environment, although theoretical and experimental aspects are also discussed. In this updated second edition, there is a greater focus on the effects of climate change and some of its likely effects on deserts, seeing desertification as among the most serious results of climate change, leading ultimately to the increasing size of arid and semi-arid regions. The Biology of Deserts Second Edition includes a wide range of ecological and evolutionary issues including morphological and physiological adaptations of desert plants and animals, species interactions, the importance of predation and parasitism, food webs, biodiversity, and conservation. It features a balance of plant and animal (both invertebrate and vertebrate) examples, and also emphasizes topical applied issues such as desertification and invasive species. The book concludes by considering the positive aspects of desert conservation. This accessible textbook is intended for senior undergraduate and graduate students, as well as professional ecologists, conservation practitioners, and resource managers working in the field of desert ecology.

Book Description
This collection reviews current research on understanding nutrient cycles, the ways crops process nutrients, the environmental effects of fertilizer use and how this understanding can be used to improve nutrient use efficiency for a more resource-efficient and climate-smart agriculture. Parts 1-3 summarise research on the primary macronutrients: nitrogen, phosphorus and potassium. Chapter review what we know about nutrient cycles, crop nutrient processing, potential environmental effects and ways of optimising nutrient use efficiency (NUE). The fourth section of the book discusses secondary macronutrients and micronutrients including: calcium, magnesium, sulphur, zinc, boron, manganese and molybdenum. The final two parts of the book review research on optimising fertiliser use. Chapters cover topics such as assessing nutrient availability, decision support systems for optimising crop nutrition, advances in site-specific nutrient management and advances in integrated plant nutrient management. Other chapters discuss enhanced efficiency fertilisers, the use of bio-effectors/bio-stimulants, fertigation techniques and the use of organic amendments. With its distinguished editor and international team of expert authors, this will be a standard reference on optimising crop nutrition for the crop science and farming community.

Book Description
The current agricultural plant production system is dominated by mono-cropping with genetically uniform cultivars. This genetic erosion has led to a displacement of locally adapted landraces and cultivars and poses a serious threat to plant productivity in stressed agro-ecosystems. The adaptation of crops to drought, heat, salinity, and low soil fertility is becoming paramount due to global climate change. Utilizing exotic or underused germplasms as a source of adaptive traits is a largely untapped way to ensure a stable yield. The task to apply biodiversity in crop production to confer food security and sustainability was acknowledged by the Food and Agriculture Organization of the United Nations and reflected by the United Nations Sustainable Development Goals. In many parts of the world, poor soil fertility threatens yield stability. Therefore, the soil nutrient reserve must be replenished to sustain crop yield. Mineral fertilizer in excess, however, is detrimental to the environment. For instance, elevated loads of nitrogen, phosphorus, or chlorine pollute water bodies and impact on biodiversity. Major anticipated concerns for our agricultural systems are the limitation in phosphorus, temperature increase, extreme and unpredictable weather events, and salinity. Therefore, environmentally friendly strategies to optimize nutrient cycling are urgently required and this involves increasing nutrient use efficiency. In the face of climate change, it is necessary to mine crop biodiversity to increase nutrient uptake and usage, and to help implement a "Zero-Waste" concept in plant nutrition. This Research Topic is intended to provide an updated view on the use of crop biodiversity to open new avenues for improved nutrient cycling. We welcome contributions (Original Research, Review, Mini Review, and Perspective) covering any of the following aspects: - Studies on improving nutrient fluxes through control of production factors both in controlled environments and in the field (horticulture/agriculture) - Screening and application of genebank material for improved nutrient use efficiency - Studies on the effect of combining (novel) crop species (multi-cropping, intercropping, rotations, cover cropping) on crop performance and nutrient availability - Effect of mutualistic species (mycorrhiza or bacteria) on nutrient cycling; e.g. improvement of nutrient uptake and by mutualism. - Climate change-driven effects on nutrient cycling; e.g. how do different temperatures/precipitation influence nutrient cycling through soils?

Book Description
Plants require a proper balance of matter and energy to maintain their survival and reproduction. Biotic and/or abiotic stresses in diverse environments could influence plant photosynthesis, water and nutrient acquisition and utilization. Through the lens of plant physiological and functional ecology, the study of responses of individual plant traits and/or integration of plant responses to environmental change has been well developed. The variation of plant physiological characteristics and functional traits has been recognized with hundreds of high-quality papers on topics of plant responses to environmental stresses. For now, despite the increasing number of studies trying to establish a linkage between plant physiological processes and functional traits, these covariations have received limited theoretical and experimental verification. This knowledge gap hampers our ability to understand and predict the comprehensive responses of plants to environmental stresses at different scales.
