  • “Biofortification” boosts nutrients in Africa’s staple crops

    Whether a bowl of rice or a piece of bread, staple foods provide millions of poor people around the world with a source of basic sustenance day in and day out. Now, a new technology promises to make these foods-which provide calories but do not always contain enough of the micronutrients required for good health-more nutritious. People who intake insufficient amounts of iron, zinc, and vitamin A ...

  • Integrating animal and crop production can reduce nutrient leaching from agricultural fields

    Nutrient leaching, the movement of plant nutrients from soil to water, can have negative effects on aquatic ecosystems due to eutrophication, which reduces the oxygen available in water, causing species and habitat loss. Ecological Recycling Agriculture (ERA), which is based on ecological principles and integrates crop production and animal husbandry, may limit this effect. This study ...

  • 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 ...

  • Free webinar: Managing nutrients after the drought

    Join a panel of experts as they discuss how to practice good nutrient management in the wake of this year's drought Sponsored by the Agricultural Nutrient Policy Council and hosted by the American Society of Agronomy The drought of 2012 will long be remembered for its devastating effects on crops across a huge swath of North America's most productive soils. And ...

  • Nutrient Management Plans: A Study in Cause and Effect

    It seems practical on the surface. Nutrient management plans (NMPs) should supply plants with ideal amounts of nutrients, minimize runoff, and maintain or even improve the soil condition. And the farmer behind the plan would work with a set of conservation practices designed to reduce harmful pollutants while still obtaining optimal crop yields. However, many U.S. Animal Feeding Operations (AFOs) ...

  • Can GM crops feed the hungry?

    Golden Rice burst into the public imagination a decade ago, in the form of a cover article in Time magazine that claimed the genetically modified (GM) rice could 'save a million kids a year'. The rice gets its golden hue from an excess of beta carotene, a precursor to vitamin A that could help half a million children who go blind each year from an often-fatal vitamin A deficiency. But ten years ...

  • 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, ...

  • Beet your Molasses requirements with dedicated Molasses Tanks

    Towards the end of the summer, attention gradually shifts towards providing for livestock throughout the winter months, and along with the impending beet crops, the production and storage of molasses is once more back on the agenda. Across many livestock and dairy farms, molasses forms the basis of numerous feed formulas. As we all know, molasses provide a number of core nutrients for cattle and ...

  • Diversifying crops `could green African agriculture`

    The biodiversity of crop fields could be key to a greener revolution in Africa, where ecosystems are degrading and crop yields are stagnating, says a study conducted in Malawi. African farmers could halve their fertiliser use and still get the same yields, the study found, with less year-to-year variation in yields and with as much as 70 per cent more protein in grains — by simply rotating ...

  • Genetically Modified Crop Industry Continues to Expand

    One of the familiar narratives for the promotion of genetically modified (GM) crops is that they have the potential to alleviate poverty and hunger. But the real impacts of GM crops deserve closer assessment, writes Wanqing Zhou, research associate in the Food and Agriculture Program at the Worldwatch Institute, in the Institute’s latest Vital Signs Online article ...

  • Improve crop yield by removing manure solids

    Manure has long been used as a crop fertilizer, but the challenge of finding an efficient use of the nutrients found in manure is ever present. The ratio of nitrogen to phosphorus in manure is low in relation to the nutrient needs of most crops. Therefore, crops tend to be overloaded with manure to meet the nitrogen requirement of agricultural crops, but the excess phosphorus from the process can ...

  • Corn out earns energy crops—for now

    Corn stover is the most profitable cellulosic biofuel feedstock on cropland in the Great Lakes Region at current prices. For perennial biomass crops to earn farmers more than corn, prices or yields would have to change. At biomass prices of US$110–US$130 per metric ton or yield gains of 50–60%, poplar, switchgrass, and mixed grasses would become attractive. If prices of expensive U.S. miscanthus ...

  • Using rotation crops to improve soil quality

    Soil quality issues are being researched within two crop rotation experiments that started in 1994 at Narrabri. They compare several crop rotations that include or exclude legume phases. The data presented here relate to the most recent 2-year cycles of these experiments. Following cotton harvest at the end of the previous cycle, rotation crops are sown (winter cereal, faba beans (grain) or vetch ...

  • Keeping tabs on the next generation of transgenic crops

    A team of government and university crop scientists from across Canada has developed a scientific framework for monitoring the release of second-generation genetically modified crops. The framework is designed to assess the risks of novel genes entering wild populations. First-generation genetically modified (GM)/transgenic crops with novel traits have been grown in a number of countries since ...

  • The dire need to support ‘orphan crop’ research

    In spite of debate over its definition, the term ‘orphan crops’ refers to crops that are under-researched and underfunded due to their limited importance in the global market. These include cereals, legumes, vegetables, root crops, fodder crops, oil crops, fibre crops and ...
