  • Sustainable mechanization has much to offer in sub-Saharan Africa

    Feeding the burgeoning world population will require significant improvements in agricultural productivity, above all in Africa, and mechanization and appropriate mechanization strategies have a large role to play, according to a new report from FAO. The opportunity must be guided in a way that meets smallholder farmers' needs and that does not require a Green-Revolution type of approach with ...

  • Manure runoff depends on soil texture

    Research has documented the rise of nutrient runoff from flat agricultural fields with high rates of precipitation that adds nitrates and phosphates to waterways. These nutrients increase the amount of phytoplankton in the water, which depletes oxygen and kills fish and other aquatic creatures. While injecting animal manure slurry into the soil has been proven to be an effective way of reducing ...

  • Scientists to map out earth`s soil

    Some of the answers to the world’s greatest challenges -- such as climate change, food security, and water scarcity -- lie right beneath our feet. Responding to these and other critical issues, a group of scientists from around the world have announced an ambitious new plan to digitally map the Earth’s soil and its properties. Scientists, industry leaders, and government officials gathered ...

  • Business commits to UNCCD capacity building for soil leadership

    UNCCD today launched a Soil Leadership Academy with support from the World Business Council for Sustainable Development (WBCSD) and leading WBCSD member Syngenta and called on other business and stakeholders to join. The main goal of the joint initiative is to fill the gap in capacity building opportunities for policy makers to address land management issues, through distilling and sharing the ...

  • Satellites help map soil carbon flux

    Changes in soil carbon occur with changes in land management. Scientists at Oak Ridge National Laboratory and the University of Tennessee investigated quantifying soil carbon changes over large regions. They integrated remote sensing products with a national carbon accounting framework in a project funded by the U.S. National Aeronautics and Space Administration, Office of Earth Science. Results ...

  • Through microbes, nitrogen alters soil carbon cycle

    Soil scientists studying bacterial communities in hardwood forests have found evidence that extra human-derived nitrogen deposited from the atmosphere can change the composition of the soil microbial community, with implications for carbon cycling and sequestration. Don Zak and Sarah Eisenlord from the University of Michigan conducted a study on the response the soil bacterial community to levels ...

  • Carbon payments `could help enrich African soil`

    Paying farmers in Sub-Saharan Africa to sequester carbon may provide a stronger incentive to improve soil quality than simply offering official fertiliser subsidies, a modelling study has found. In recent years, fertiliser subsidies have been vigorously promoted to farmers in countries like Ghana, Kenya, Malawi, Tanzania and Zambia. But despite widespread levels of soil degradation, take-up rates ...

  • African soil diversity mapped for the first time

    A team of international experts has drawn up the Soil Atlas of Africa — the first such book mapping this key natural resource — to help farmers, land managers and policymakers understand the diversity and importance of soil and the need to manage it through sustainable use. They say that despite soil's importance, most people in Africa lack knowledge about it, partly because ...

  • Research to restore the fertility of earth`s soils

    In keynote addresses at the FAO Workshop on Sustainable Agriculture in Riyadh, Saudi Arabia on April 28 and April 29, 2009, soil fertility experts from the Nutrition Security Institute, (NSI) a non-profit organization located in Bellevue, Washington, presented advances and understandings in biotic soil fertility as a proven solution to the serious problems facing global agriculture. Their dual ...

  • Unique Acacia tree`s promise to revive African soils

    Scientists said at the 2nd World Congress of Agroforestry that a type of acacia tree with an unusual growth habit-unlike virtually all other trees-holds particular promise for farmers in Africa as a free source of nitrogen for their soils that could last generations. With its nitrogen-fixing qualities, the tall, long-lived acacia tree, Faidherbia albida (Mgunga in Swahili) could limit the use of ...

  • Some but not all plants can defend themselves against disease on saline soil

    Some plants with resistance against a specific disease are also able to defend themselves effectively when they are stressed due to, for example, drought or saline soil. At the same time, the resistance of other plants no longer functions in these very same conditions. Although this had been assumed for some time, Wageningen scientist Christos Kissoudis is the first person to show why. As a ...

  • Science preview: October 2012 meetings of agronomy, crop, and soil science societies

    How are manufactured nanoparticles affecting the world’s terrestrial and aquatic ecosystems? What are the linkages between organic farming, healthy soils, and healthy foods? Can “grey” wastewater be safely used to irrigate farmland and replenish groundwater supplies? What strategies are underway around the world to sustain food security in the face of climate change? These are ...

  • Global plans of action endorsed to halt the escalating degradation of soils

    Urgent action is required to improve the health of the world's limited soil resources and stop land degradation, so as to ensure that future generations have enough supplies of food, water, energy and raw materials, government representatives and experts meeting at FAO warned today. The Global Soil Partnership has endorsed a series of action plans ...

  • GM crops can thrive as climate warms

    Genetically engineering photosynthesis in plants could take advantage of rising global temperatures and increased levels of carbon dioxide, US scientists say. They believe this could achieve much higher yields on the same amount of land and help to stave off the prospect of widespread hunger as human populations increase. Researchers at ...

  • Quantum leap taken in measuring greenhouse effect

    British scientists have devised a new way to observe the greenhouse world, enabling researchers to measure with exquisite accuracy how atmospheric carbon dioxide builds up, migrates, evolves and absorbs radiation. The technique will allow more accurate predictions about how much the Earth is likely to warm over the next few ...

  • Application for the calculation of C02 balance in olive farming

    We now have evidence that, when the appropriate agricultural practices are applied, the carbon sink effect (or carbon sequestration) of olive trees through the biomass and soil is much greater than the greenhouse gas emissions for one production unit (one litre of virgin olive oil). According to Environmental Product Declarations for olive oil and published research, on average 1.5 kg of CO2e is ...
