  • Herbicide reduction can preserve crop yields as well as biodiversity benefits of weeds

    Pesticide-sparing approaches to farming do not have to compromise on crop yields, new research suggests. A study that explored the impact of reduced herbicide use across a variety of different farming contexts found that herbicideefficient systems could be just as productive as conventional systems — and more so than organic systems — whilst having other important environmental ...

  • Agricultural ammonia emissions could be reduced without affecting crop yield

    Ammonia released by nitrogen fertilisers in Spanish agriculture could be reduced by up to 82% with only a very minimal impact on crop yield, finds new research. This could be achieved by combining optimised management of manure with the use of non-urea synthetic fertilisers. Agriculture accounted for almost 94% of total European atmospheric emissions of ammonia in 2011. The main sources of these ...

  • Patches of flowers boost pollinator diversity and lead to higher crop yields

    Falling levels of insect pollination are causing declining yields of important agricultural crops. However, new research from South Africa now indicates that planting small patches of native flowers in agricultural fields can be a profitable and sustainable method of increasing pollination and yield. Insect pollination is a vital ecosystem service as animal-pollinated crops form an ...

  • Weather extremes slash cereal yields

    Climate change may have already begun to take its toll of agriculture. New research suggests that drought and extreme heat in the last 50 years have reduced cereal production by up to 10%. And, for once, developed nations may have sustained greater losses than developing nations. Researchers have been warning for years that ...

  • New report finds green investments in South Africa could spur growth and jobs while enhancing crop yields, water supplies and land restoration

    Improving the management of natural resources and investing in the environment could increase South Africa’s crop yields by almost a quarter, create 170,000 additional jobs, and significantly increase the availability of water, compared to current practices. These are among the key findings of a new report released today by South Africa’s Minister of Water and Environmental Affairs ...

  • Rice yields targetted in first CGIAR `mega-programme`

    Farmers could benefit from increased rice yields and new varieties of the staple crop adapted to climate change, with the launch of a global research programme that aims to lift millions out of hunger and poverty by 2035. The Global Rice Science Partnership (GRiSP) was launched by the Consultative Group on International Agriculture Research (CGIAR) at the 3rd International Rice Congress in Hanoi, ...

  • Counting the cost of ozone pollution on crops

    A recent study has calculated crop losses as a result of surface ozone pollution. The study suggests that future earnings will be significantly reduced by ozone damage to crops, especially for some developing and agriculture-dependent countries. Surface ozone is an air pollutant that forms as a result of chemical reactions between other pollutants, particularly emissions from motor vehicles and ...

  • CSIRO and Bayer to focus on sustainable crops

    This collaboration will develop and apply models to assess the system-wide consequences of new-generation cereal crops in the face of global environmental and food security challenges. The project will assess the full environmental impact of the crops, including their influence on the carbon footprint of cereal production. This program will build on a long-term cereal research agreement between ...

  • Cover crops reduce erosion, runoff

    Cover crops may be more effective at reducing soil erosion and runoff after maize harvest than rough tillage, according to scientists from the Université Catholique de Louvain, in collaboration with the Independent Center for the Promotion of Forage (CIPF). The three-year study, supervised by Charles Bielders and conducted by Eric Laloy, measured erosion and runoff losses from silt loam ...

  • BiOWiSHâ„¢-Crop receives Organic Certification

  • Rice Farmers in China use Less Fertilizer, Increase Yield

    “Rice farmers can decrease their nitrogen fertilizer and pesticide use by around 20%, and increase their yield by 10% by using the ‘three controls technology’ (3CT),” says Dr. Xuhua Zhong, crop physiologist at the Rice Research Institute of the Guangdong Academy of Agricultural Sciences (GDRRI).  The meaning of “three controls” is controlling the amount of ...

  • Rise in CO2 could restrict growing days for crops

    The positive consequences of climate change may not be so positive. Although plants in the colder regions are expected to thrive as average global temperatures rise, even this benefit could be limited. Some tropical regions could lose up to 200 growing days a year, and more than two billion rural people could see their hopes wither on the vine or in the field. Even in temperate zones, there will ...

  • Lack of data on droughts hampers risk reduction efforts

    Droughts pose a "hidden risk" as they are poorly understood and lack reliable data that could inform mitigation strategies, says a report on global disaster risk. Lack of systematic monitoring means that the risk of impeding drought is largely invisible despite having significant effects on agricultural production, rural livelihoods and economies, says 'Global Assessment Report on Disaster Risk ...

  • Syria: Poor crop prospects reflect the impact of continued conflict and drought conditions

    Drought conditions combined with continued conflict are adding pressure to an already dire food security situation in the Syrian Arab Republic, raising the prospect of further severe reductions in wheat and barley production in key areas, along with increased food import needs and higher prices for 2014, FAO reports. Wheat and barley are the country’s two most important food crops. The ...

  • Halving EU meat and dairy consumption yields lower pollution and land use, and better health

    Halving meat and dairy consumption in Europe could reduce agricultural greenhouse-gas emissions by up to 42% and nitrogen pollution by 40%, new research suggests. The amount of land needed to grow food for each EU citizen would fall from 0.23 to 0.17 hectares and the reduced intake of saturated fats and red meat could have substantial health benefits, the researchers conclude. The Roadmap to a ...
