This open access book distinguished itself from other publications by offering step-by-step instructions on how to extract, purify, provide modifications, and major issues to be encountered during the process. For the 18OP method to progress, further fundamental research as well as field and laboratory studies need to be conducted for a better understanding of P cycling in the environment. Chapter 1 outlines the background and examples of 18Op studies in sediments, soils, fresh water, mineral fertilizers, and plants. Chapters 2 and 3 examine the stepwise extraction and purification protocols including reagents, equipment and consumables and preparations for analyses. Chapter 4 examines some of the challenges and modifications during the purification process. Chapter 5 discusses planning and designing of a study using 18Op, external quality assurance with an example of an inter-laboratory study. Chapter 6 outlines the conclusions, future trends, and opportunities, the scaling out of the method from laboratory to field studies. It is expected that the 18OP would be extensively applied in research geared to understand phosphorus dynamics in different agro-environments. .

Phosphorus (P) is a finite resource which is essential for life. It is a limiting nutrient in many ecosystems but also a pollutant which can affect biodiversity in terrestrial ecosystems and change the ecology of water bodies. This book collects the latest information on biological processes in soil P cycling, which to date have remained much less understood than physico-chemical processes. The methods section presents spectroscopic techniques and the characterization of microbial P forms, as well as the use of tracers, molecular approaches and modeling of soil-plant systems. The section on processes deals with mycorrhizal symbioses, microbial P solubilization, soil macrofauna, phosphatase enzymes and rhizosphere processes. On the system level, P cycling is examined for grasslands, arctic and alpine soils, forest plantations, tropical forests, and dryland regions. Further, P management with respect to animal production and cropping, and the interactions between global change and P cycling, are treated.

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.

It is commonly acknowledged that the cycling of nutrients, including phosphorus (P) and nitrogen (N), from plant residues in crop rotations is important for the sustainability of agricultural systems. This is especially the case for Australian low input rain-fed cropping systems, where, due to economic, climatic and edaphic factors, additions of P and N as fertilizers or manures are limited. Optimal management of P and N cycled from break crop residues requires a sound understanding of the quantity of each nutrient in residues and what proportion potentially becomes available for a following cereal crop. A review of the literature (Thesis Chapter 1) highlighted that whilst there is information concerning quantities of N, and to a lesser extent P, contained in mature above-ground crop residues, much less has been reported concerning quantities of P or N of below-ground (BG) residues from various crop species. This is partly because root studies are time consuming and hence expensive to undertake, but also quantification is hampered by the certainty that not all roots can be recovered from soils, especially in fine textured soils. As a result root turnover and nutrient release have largely been investigated under somewhat 'artificial' or 'unrealistic' conditions - using roots that have been extracted from soil, dried, often chopped or finely ground and finally incorporated back into soil to decompose. More recent innovative studies, summarised in the review (Chapter 1), have used a stem wick-feeding technique to label crop root systems in situ with the 15N isotope. These studies demonstrated that total BG N accumulation for these crop species was larger than quantified from recovered roots alone. The labelling technique allowed for direct in situ quantitative tracing of the N from legume and oilseed root residues into subsequent wheat plants. It was demonstrated that up to 20% of wheat N uptake may be derived from the BG N input by root systems of a previous break crop. The review (Chapter 1) further highlighted that quantitative assessment of the amounts of P accumulated by crop root systems were extremely scarce and there did not appear to be any in situ isotope studies related to P accumulation BG. Hence the work described in this thesis broadly explored the potential to adapt the approaches used for 15N isotope studies in order to quantitatively assess in situ P accumulation BG by break crop species in soils differing in texture, and the uptake of P derived from those BG break crop residues by a following wheat plant. The specific aims of the work were: i) to adapt the stem wick-feeding technique for use with 33P to allow in situ quantification of total BG P accumulation by plants, ii) to quantify and compare BG P in two break crops species (an oilseed and a legume) important in Australian rain-fed cropping systems, iii) to assess and measure whether soil texture influences BG P accumulation in canola (oilseed) and lupin (legume), and iv) to trace the fate of break crop BG P relative to BG N in a following cereal (wheat).

Due to the rapid increase in world population and improving living standards, the global agriculture sector is confronting with challenges for the sustainability of agricultural production and of the environment. Intensive high-yield agriculture is typically dependent on addition of fertilizers (synthetic chemicals, animal manure, etc.). However, non-point nutrient losses from agricultural fields due to fertilization could adversely impact the environment. Increased knowledge on plant nutrient chemistry is required for improving utilization efficiency and minimizing loses from both inorganic and organic nutrient sources. For this purpose, the book is composed of 19 chapters that highlight recent research activities in applied nutrient chemistry geared toward sustainable agriculture and environment. Topics of interest include, but are not limited, to speciation, quantification, and interactions of various plant nutrients and relevant contributories in manure, soil, and plants. This book outlooks emerging researchable issues on alternative utilization and environmental monitoring of manure and other agricultural by products that may stimulate new research ideas and direction in the relevant fields.

The world population is projected to reach nine billion by 2050, and in the coming years, global food demand is expected to increase by 50% or more. Higher crop productivity gains in the future will have to be achieved in developing countries through better natural resources management and crop improvement. After nitrogen, phosphorus (P) has more widespread influence on both natural and agricultural ecosystems than any other essential plant element. It has been estimated that 5.7 billion hectares of land worldwide contain insufficient amounts of available P for sustainable crop production, and P deficiency in crop plants is a widespread problem in various parts of the world. However, it has been estimated that worldwide minable P could last less than 40 years. For sustaining future food supplies, it is vital to enhance plant P use efficiency. To bring the latest knowledge and research advances in efficient management of P for economically viable and environmentally beneficial crop production in sustainable agriculture, Phosphorus Management in Crop Production contains chapters covering functions and diagnostic techniques for P requirements in crop plants, P use efficiency and interactions with other nutrients in crop plants, management of P for optimal crop production and environmental quality, and basic principles and methodology regarding P nutrition in crop plants. The majority of research data included are derived from many years of field, greenhouse, and lab work, hence the information is practical in nature and will have a significant impact on efficient management of P-fertilizers to enhance P use efficiency, improve crop production, promote sustainable agriculture, and reduce P losses through eluviations, leaching, and erosion to minimize environmental degradation. A comprehensive book that combines practical and applied information, Phosphorus Management in Crop Production is an excellent reference for students, professors, agricultural research scientists, food scientists, agricultural extension specialists, private consultants, fertilizer companies, and government agencies that deal with agricultural and environmental issues.
