  • Endocrine Disruption in Fish

    Endocrine Disruption in Fish

    There is increasing concern in the media, among politicians and within environmental organizations, about the effects of chemicals in our environment that affect the endocrine systems of wildlife and humans. At its simplest these are referred to as 'gender-bending' chemicals or 'environmental estrogens'. The chemicals in question (pesticides, PCBs, plasticizers, petrochemicals, and a variety of industrial chemicals) have been known to ...

  • Fertilizers and Environment

    Fertilizers and Environment

    Food production remains the highest agricultural priority, subject to the constraint that it be done in harmony with nature, or at least with minimum environmental pollution. The amount of fertilizer applied can be controlled using modern application techniques, including soil and crop management, guaranteeing higher economic profit and lower environmental cost. It is in such a context that the present book addresses the efficient and ...

  • Grassland Invertebrates

    Grassland Invertebrates

    Grasslands comprise more than a quarter of the Earth's land surface. In addition to supporting a wide range of vertebrates such as domestic livestock and a variety of games species, grassland is the natural habitat for a wide range of invertebrate species, and this book considers those which occur in grassland and their impact on soil fertility and herbage growth. It describes grassland as a habitat for invertebrates, the groups which ...

  • Improving Efficiency of Urea Fertilizers by Inhibition of Soil Urease Activity

    Improving Efficiency of Urea Fertilizers by Inhibition of Soil Urease Activity

    This book is a comprehensive and updated review of fundamental studies on inhibition of soil urease activity and of applied studies on improving efficiency of urea fertilizers by inhibition of soil urease activity. The general literature on these topics covers 65 years and the patent literature comprises a period of nearly 40 years. The potential of food production to meet the growing needs related to population increase is largely conditioned ...

  • Managing Organic Matter in Tropical Soils: Scope and Limitations

    Managing Organic Matter in Tropical Soils: Scope and Limitations

    Soil organic matter is a reservoir for plant nutrients, provides water-holding capacity, stabilizes soil structure against compaction and erosion, and thus determines soil productivity. All agriculture to some degree depends on soil organic matter. It has long been known that soil organic matter declines when land is taken into cultivation, and that the productivity of new agricultural land is governed by fertility contributions from decomposing ...

  • Plant-Induced Soil Changes: Processes and Feedbacks

    Plant-Induced Soil Changes: Processes and Feedbacks

    This book by soil scientists and ecologists reviews how and why plants influence soils. Topics include effects on mineral weathering, soil structure, and soil organic matter and nutrient dynamics, case studies of soil-plant interactions in specific biomes and of secondary chemicals influencing nutrient cycling, the rhizosphere, and potential evolutionary consequences of plant-induced soil changes. This is the first volume that specifically ...
