  • Algae and their Biotechnological Potential

    Algae are important organisms that include seaweeds and a number of single-celled and multicellular microscopic forms. Algae are ubiquitous; they inhabit almost everywhere including oceans, freshwater bodies, rocks, soils, and trees. Man's uses of algae may date back to ancient times. In recent decades, there has been renewed interest in the ...

  • Unlocking the water potential of agriculture (En)

    Series: Non-series TitlesAll statistical evidence confirms that agriculture is the key sector for water management, now and in the next decades. Nevertheless, the rural water development sector fails at present to get priority, compared to other competing sectors, in international fora. Strong and new arguments are needed to bring rural water back ...

  • The Fish Production Potential of the Baltic Sea

    It presents a new approach to set fish quota based on holistic ecosystem modeling (the CoastWeb-model) and also a plan to optimize a sustainable management of the Baltic Sea including a cost-benefit analysis. This plan accounts for the production of prey and predatory fish under different environmental conditions, professional fishing, ...

  • Guidelines for soil description. Fourth edition (En)

    Soils are affected by human activities, such as industrial, municipal and agriculture, that often result in soil degradation and loss. In order to prevent soil degradation and to rehabilitate the potentials of degraded soils, reliable soil data are the most important prerequisites for the design of appropriate land-use systems and soil management ...

  • 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 ...

  • Experiences of Farmer Participation in Soil Fertility Research in Southern Zimbabwe

    This working paper discusses the impact of a multi-institutional research programme in low potential areas of Kenya. The programme elaborated nutrient balances, combined with economic analysis, to better understand causes and effects of soil fertility decline. Alongside, better soil fertility management practices were developed using a ...

  • Belowground Responses to Rising Atmospheric CO2: Implications for Plants, Soil Biota, and Ecosystem Processes

    As atmospheric CO2 increases there will almost certainly be alterations in soil carbon fluxes. It is likely that such alterations will be accompanied by changes in the partitioning of carbon between organic structures and to soil processes. These changes have the potential for further altering the structure and function of terrestrial ...

  • Lubrication in Inland and Coastal Water Activities

    This book describes successful experiences of many companies, institutions and individual users in Germany, the Netherlands, Belgium, France and Spain, that are willing to apply 'bio'lubricants in their equipment and ready to monitor the effects. Their experiences are summarized in useful tips that help the potential user to realize a successful ...

  • Plantations in the tropics : environmental concerns

    Based on thorough bibliographic research of a highly controversial topic, this report, jointly sponsored by IUCN, UNEP and WWF, shows the potential of plantations, while also exposing problems which may arise if massive tree plantations proposed for the tropics are to be established. Major issues covered include; species selection, soil and water ...

  • Sulphur in Agroecosystems

    This is the second volume in the series Nutrients in Ecosystems. Sulphur as an essential plant nutrient has received little attention. This is explained by the facts that sulphur was obviously in sufficient supply from the atmosphere, from soil and as a by-product in mineral fertilizers. Increases in the yield potential and thus in the ...

  • Ethylene

    This revolutionary book examines the biochemistry of endogenous ethylene biosynthesis and its role in the physiology of higher plants. Never before has such comprehensive attention been given to soil microbiota and their potential exogenous source of ethylene. This book provides chapters examining ethylene as a hormone, its role in plant ...

  • Phenology of Ecosystem Processes

    Terrestrial carbon balance is uncertain at the regional and global scale. A significant source of variability in mid-latitude ecosystems is related to the timing and duration of phenological phases. Spring phenology, in particular, has disproportionate effects on the annual carbon balance. However, the traditional phenological indices that are ...
