Available in PDF, EPUB and Kindle. Book excerpt: The interactions between the plant, soil and microbes are complex in nature. Events may be antagonistic, mutualistic or synergistic, depending upon the types of microorganisms and their association with the plant and soil in question. Multi-trophic tactics can therefore be employed to nourish plants in various habitats and growth conditions. Understanding the mechanisms of these interactions is thus highly desired in order to utilize the knowledge in an ecofriendly and sustainable way. This holistic approach to crop improvement may not only resolve the upcoming food security issues, but also make the environment greener by reducing the chemical inputs. Plant, soil and microbe, Volume 1: Implications in Crop Science, along with the forthcoming Volume 2: Mechanisms and Molecular Interactions, provide detailed accounts of the exquisite and delicate balance between the three critical components of agronomy. Specifically, these two titles focus on the basis of nutrient exchange between the microorganisms and the host plants, the mechanism of disease protection and the recent molecular details emerged from studying this multi-tropic interaction. Together they aim to provide a solid foundation for the students, teachers, and researchers interested in soil microbiology, plant pathology, ecology and agronomy.

Available in PDF, EPUB and Kindle. Book excerpt: Protists are by far the most diverse and abundant eukaryotes in soils. Nevertheless, very little is known about individual representatives, the diversity and community composition and ecological functioning of these important organisms. For instance, soil protists are commonly lumped into a single functional unit, i.e. bacterivores. This work tackles missing knowledge gaps on soil protists and common misconceptions using multi-methodological approaches including cultivation, microcosm experiments and environmental sequencing. In a first part, several new species and genera of amoeboid protists are described showing their immense unknown diversity. In the second part, the enormous complexity of soil protists communities is highlighted using cultivation- and sequence-based approaches. In the third part, the present of diverse mycophagous and nematophagous protists are shown in functional studies on cultivated taxa and their environmental importance supported by sequence-based approaches. This work is just a start for a promising future of soil Protistology that is likely to find other important roles of these diverse organisms.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents the soil pedodiversity in Libya. Soils are the source of all life; there can be no life without them. Further, each soil has its own history and its present conditions, which have been shaped by many different factors (e.g. climate, biota, parent material, and relief or topography). The book, divided into eight chapters, provides extensive information on Libyan soils. Chapter one provides an introduction and a broad perspective of the subject, while Chapter two covers the history of soil mapping and research in Libya. Chapter three focuses on local factors of soil formation and describes the geology and climate of the region to explain the diversity of its soils. Chapter four discusses soil classification systems and those most commonly used in the country. The fifth chapter illustrates the constraints and limiting factors that negatively affect agricultural activities across the country. The land cover/land use and the vegetation of the country are described in Chapter six. In turn, Chapter seven presents the status quo of soil biology, the corresponding related research activities, and the other biological properties of Libyan soils. The final chapter (Chapter eight) focus on land degradation and desertification in Libya, emphasizing the main causes, impacts of the phenomena, and efforts to combat it. This book demonstrates the problems that the country is currently facing as a result of climate change, soil erosion, salinization, and pollution, and outlines potential remedies to improve local food security. Bringing together the perspectives and expertise of many distinguished scientists from various universities and institutions in and outside of Libya, the book represents a unique and highly valuable resource.
