  • Nutrient Management: Regulatory Approaches to Protect Water Quality

    Utilities work with regulators to treat wastewater to levels that protect human health and ecosystems.  Water quality criteria and permits are based on scientifically defensible and shared understanding of sources of pollutants in a watershed, as well as treatment capabilities and costs to control these in the aquatic environment.  The national ...

  • Guide to laboratory establishment for plant nutrient analysis

    This publication provides practical guidelines on establishing composite service laboratories for the analysis of soil, plants, water and fertilizers (mineral, organic and biofertilizers). It also provides various analytical methods for assessing soil fertility and making nutrient recommendations, assessing quality of irrigation water, and details ...

  • Fingerponds: Managing Nutrients & Primary Productivity For Enhanced Fish Production in Lake Victoria’s Wetlands Uganda

    This study examines fingerponds in the Lake Victoria wetlands in Uganda. It discusses the importance of organic manure applications in enhancing nutrient levels, phytoplankton, and periphyton productivities and ultimately fish production. The study demonstrates that organic manures enhance algal development and fish production, emphasizing that ...

  • Importance of soil organic matter, (The). Key to drought-resistant soil and sustained food production (English)

    Series: FAO Soils BulletinsSoil organic matter - the product of on-site biological decomposition - affects the chemical and physical properties of the soil and its overall health. Its composition and breakdown rate affect: the soil structure and porosity; the water infiltration rate and moisture holding capacity of soils; the diversity and ...

  • Pacific Islands food composition tables, (The). Second edition (En)

    Traditional Pacific Island diets were diverse and nutritionally appropriate. In recent decades Pacific Islanders have experienced many changes in lifestyle and diet. Most of the dietary changes have not been for the better, and have contributed to the burden of malnutrition throughout the Pacific. The vast natural biodiversity of food plants and ...

  • Scaling soil nutrient balances. Enabling mesolevel applications for African realities (En)

    Series: FAO Fertilizer and Plant Nutrition BulletinsUsing data on three countries in sub-Saharan Africa, this report compares macro- and microlevel approaches to determine soil nutrient balances with an innovative mesolevel approach. It highlights the added value that a mesolevel approach can provide in terms of its usefulness to mesolevel ...

  • Glossary of Soil Science Terms, 2001 Edition

    More than 1800 terms are included in this newly revised glossary. Subject matter includes soil physics, soil chemistry, soil biology and biochemistry, pedology, soil and water management and conservation, forest and range soils, nutrient management and soil and plant analysis, mineralogy, wetland soils, and soils and environmental quality. Two ...

  • 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 ...

  • Gradients in a Tropical Mountain Ecosystem of Ecuador

    A tropical mountain ecosystem in one of the 'hottest' biodiversity hotspots worldwide was investigated by some 30 research teams of numerous disciplines in the natural and social sciences. Ecosystem analysis followed two gradients: an altitudinal gradient and a gradient of land-use intensity and ecosystem regeneration, respectively.This volume ...

  • North American Temperate Deciduous Forest Responses to Changing Precipitation Regimes

    Large-scale experimentation allows scientists to test the specific responses of ecosystems to changing environmental conditions. Researchers at Oak Ridge National Laboratory together with other Federal and University scientists conducted a large-scale climatic change experiment at the Walker Branch Watershed in Tennessee, a model upland hardwood ...

  • Advances in Nitrogen Management for Water Quality

    Scientific literature provides overwhelming evidence of the importance of managing nitrogen (N) to protect water quality as well as the environment in general. The goal of this chapter is to address many of the questions concerning this subject. Enhanced N management is increasingly necessary to decrease the impacts that excessive amounts of N in ...

  • Salinity and Water Stress

    Salinity and water stress limit crop productivity worldwide and generate substantial economic losses each year, yet innovative research on crop and natural resource management can reveal cost-effective ways in which farmers can increase both their productivity and their income.Presenting recent research findings on salt stress, water stress and ...

  • 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 ...
