  • World Soil Day hails symbiotic role of pulses to boost sustainable agriculture

    Soil and pulses can make major contributions to the challenge of feeding the world's growing population and combating climate change, especially when deployed together, according to Soils and Pulses: Symbiosis for Life, a new report by the UN Food and Agriculture Organization released on  ...

  • Arsenic in irrigation water is transferred to crops

    A team of researchers from the University of Valladolid (UVA) and the Salamanca Institute of Natural Resources and Agrobiology (IRNASA-CSIC) has shown that potatoes irrigated with arsenic-rich water contain this element at levels up to 35 times higher than crops on which this water was not used. The scientists have also confirmed the impact of water with high arsenic content on beet, carrot and ...

  • Saltwater solution to save crops

    Technology under development at the University of New South Wales could offer new hope to farmers in drought-affected and marginal areas by enabling crops to grow using salty groundwater. Associate Professor Greg Leslie, a chemical engineer at UNSW's UNESCO Centre for Membrane Science and Technology, is working with the University of Sydney on technology which uses reverse-osmosis membranes to ...

  • Motorizing Sudanese crop irrigation

    The parched landscape of Sudan, on the southern edge of the Sahara desert, is among the world's driest regions, with a nine-month dry season and a highly unreliable rainy season. Large-scale farmers there manage to grow about half of the impoverished nation's food production with the help of motorized irrigation pumps, but for individual subsistence farmers and their families--about two-thirds of ...

  • How much water is needed to grow bioenergy crops?

    A Dutch study has assessed the water requirements of 13 bioenergy crops across the world. The findings could help select the best crops and locations to produce bioenergy. The EU climate action and renewable energy package has set a target of increasing the share of renewable energy to 20 per cent of energy used by 20201. This includes a minimum 10 per cent share for transport, which could ...

  • Cultivating crops on city rooftops

    To meet the challenges of producing food in a more environmentally-friendly way, the European Environment Agency (EEA) has called on cities to develop 'living walls' of edible plants. Through vertical farming, agriculture could become a feature of urban life, lowering energy consumption, carbon emissions and resource use in food production. By shortening the distance produce has to travel from ...

  • The future of cover crops

    Winter cover crops are an important component of nutrient cycling, soil cover and organic matter content. Although its benefits are well documented, cover crop use in farming systems is relatively low. Research has shown that time and money are the two primary reasons why farmers are hesitant to adopt the technique. Developing innovative and cost-effective crop cover systems could increase the ...

  • Cereal Crops Feeling the Heat

    LIVERMORE, California (ENS) - Warming temperatures since 1981 have caused annual losses of about US$5 billion for six major cereal crops, new research has found. This is the first study to estimate how much global food production already has been affected by climate change. From 1981 to 2002, fields of wheat, corn and barley throughout the world have produced a combined 40 million ...

  • Squeezing more crop out of each drop of water

    Studies in China and Colorado by Agricultural Research Service (ARS) scientists and cooperators have revealed some interesting tactics on how to irrigate with limited water, based on a crop’s critical growth stages. Laj Ahuja, research leader at the ARS Agricultural Systems Research Unit in Fort Collins, Colo., and colleagues conducted the studies. As one example, with wheat in China, they found ...

  • Crops and soil threatened by floods in the Midwest

    Here, in some of the best soil in the world, the stunted stalks of Dave Timmerman's newly planted corn are wilting in what sometimes look more like rice paddies than the plains, the sunshine glinting off of pools of collected water. Although time is running out, he has yet to plant all of his soybean crop because the waterlogged soil cannot support his footsteps, much less heavy machinery. Mr. ...

  • Crop yields stall in China, India

    China and India, the world's two most populous countries, are beset by stagnation in the production of staples like rice, wheat, soybean and maize (corn), says a new study on crop yield growth. Based on statistics from around the world during the 1951– 2008 period, the study 'Recent patterns of crop yield growth and stagnation', says that for some crops in China and India the spatial extent ...

  • New crop sprayer is kinder on the environment

    An EU project has developed a new crop spray system for orchards that is precise, efficient and safer for the environment. It sprays pesticides according to the needs of the crop and local environment, and can reduce spray drift by up to 80 per cent. Preliminary field tests conducted in Poland have demonstrated its effectiveness. The EU has adopted a framework directive on the sustainable use of ...

  • 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 ...

  • Reality check for `miracle` biofuel crop

    The hardy jatropha tree as a biofuel source may not be the panacea for smallholders that some have claimed, say Miyuki Iiyama and James Onchieku. It sounds too good to be true: a biofuel crop that grows on semi-arid lands and degraded soils, replaces fossil fuels in developing countries and brings huge injections of cash to poor smallholders. That is what some are claiming for Jatropha curcas, ...

  • Biodiesel Crop of the Week: Pongamia Pinnata

    Pongamia is an ancient tree that is native to India. It is frost tolerant, but not freeze-proof. It is also happens to be a legume, which is at the heart of what makes the business model so interesting. The tree yields a generous annual nut crop that is harvested with conventional shakers, such as those used by almond and other nut growers. That seed has approximately a 40 percent oil content ...

  • Cover Crops Add to Farm Sustainability

    A potentially record-setting U.S. corn harvest is underway. Many farmers can attribute the use of cover crops as one of multiple best management practices (BMPs) that help them increase yield year after year. Combined with BMPs of The Fertilizer Institute’s 4R Nutrient Stewardship program that promotes the application of nutrients at the right source, right rate, right time and right place, ...

  • Crop models help increase yield per unit of water used

    Crop water use efficiency (WUE, or yield per unit of water used), also known as crop water productivity, can be improved through irrigation management and methods, including deficit irrigation (irrigating less than is required for maximum yields) and supplemental irrigation (irrigating to supplement precipitation so as to avoid crop failure or severe yield decline). Thus, WUE is key for ...

  • Taller, thinner crop beds save money, water, other resources

    Looking out over thousands of acres of tomatoes, Miguel Talavera, director of East Coast growing operations at Pacific Tomato Grower, Ltd., marvels at the narrow lanes of fruit that are thriving in the hot Florida sun. Talavera credits increase in yield and a decrease in the use of fumigants to a collaboration with researchers and Extension faculty at the University of Florida Institute of Food ...

  • Water demand for crops may rise in northern Germany under warmer climate

    By 2070, there may be insufficient water for irrigation to ensure yields and profitability for some crops currently grown in northern Germany - if the IPCC´s worst case climate change scenario becomes a reality - new research warns. To reduce future demand for water under a changing climate, the study suggests that farmers grow different crops and change their management practices. In ...
