  • With Changing Climate, Farmers Should Prepare

    Climate change may trigger images of polar bears falling off melting ice slabs in the Arctic, but the changes are relevant for Ohio farmers as well. Winters in Ohio are warming quicker than summers are, while summer nighttime lows are increasing faster than daytime highs, said Aaron Wilson, climate specialist for Ohio State University Extension, the outreach arm of the College of Food, ...

  • Crop water use efficiency

    Crop water use efficiency (WUE), or yield per unit of water used, 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 agricultural production with limited water ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Energy crops and their environmental implications

    Interest in producing cellulosic ethanol from renewable energy sources is growing. Potential energy crops include row crops such as corn, perennial warm-season grasses, and short-rotation woody crops. However, impacts of growing dedicated energy crops as biofuel on soil and environment have not been well documented. This review article looks at the impacts of growing warm-season grasses and ...

  • 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 ...

  • Herbicide-tolerant crops can improve water quality

    The residual herbicides commonly used in the production of corn and soybean are frequently detected in rivers, streams, and reservoirs at concentrations that exceed drinking water standards in areas where these crops are extensively grown. When these bodies of water are used as sources of drinking water this contamination can lead to increased treatment costs or a need to seek alternative sources ...

  • 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 ...

  • 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 ...

  • Nitrogen recommendations based on crop reflectance

    Nitrogen fertilizer is usually applied in greater quantities to corn than almost any other crop. But when it’s applied in excess of requirements, loss of the excess fertilizer to the environment can contribute to degraded water quality. One of the challenges to making an appropriate nitrogen fertilizer recommendation is the potential variability in soil nitrogen availability that may occur ...

  • 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 ...

  • 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. ...

  • Assessing stressed crops from the sky

    In Peru, the International Potato Center (CIP), Lima, uses drones to aerially assess crop performance under different stresses, such as pests, diseases, drought and frost — all of them widespread phenomena in the Andes, one ...

  • 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 ...
