  • Fighting selenium deficiency

    Approximately 1 billion people worldwide suffer from a deficiency of selenium, an essential nutrient for liver, heart, thyroid, and immune function. Since selenium deficiency is prevalent in Southeast Asia, researchers are studying the best biofortification for lowland rice production. In a study funded by the Commonwealth Government of Australia, the soil retention of three types of selenium was ...

  • “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 ...

  • Iron deficiency in soil threatens soybean production

    An expansion of soybean production into areas where soybean has seldom, if ever, been grown can be problematic for some farmers. Soils having high pH values and large amounts of calcium and/or magnesium carbonate are notoriously iron deficient. Iron deficient soils in the North Central United States are estimated to reduce soy bean production by 12.5 million bushels every year. John Wiersma, a ...

  • Food security depends on sustainable nutrient management of soils

    Food security is being threatened by loss of soil nutrients that are essential for the high yield of crops. A recent study outlines strategies to ensure the sustainable production of food through a holistic approach to soil nutrient management. In response to the rising demand for food from an increasing world population, high-yielding crops are being grown with the help of artificial fertilisers ...

  • 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 ...

  • IAEA and HarvestPlus link to enhance nutrition in poor regions

    An IAEA technical meeting this week examined new strategies to bolster nutrition among the world’s poor. The meeting, held in joint cooperation between the IAEA and a global group of scientists and institutions called HarvestPlus, centered on a process called biofortification, a practice being used to confront nutritional deficiencies in diets among the world’s poor. “HarvestPlus is the leading ...

  • Maryland, Michigan Farmers Keep Soil, Environment Healthy

    As farming practices increasingly attract interest from the general public, two farmers are ensuring they meet public approval. They use proven management practices that focus on improving soil quality and maintaining a quality natural environment. In fact, getting the right nutrients to where they belong and in the right amounts when they’re needed enables them to improve yields while ...

  • Ending hunger in Africa

    As hunger and drought spread across Africa, there’s a huge focus on increasing yields of staple crops, such as maize, wheat, cassava, and rice. Although these crops are important for improving food security, they cannot cure malnutrition alone. There is no one-size fits all or single crop solution to solving global hunger, alleviating poverty, or protecting the environment and mitigating ...

  • Nitrogen Management Studied in Greenhouse Pepper Production

    As consumer demand for year-round fresh produce increases, vegetable and fruit producers are facing significant environmental and sustainability issues, and are being challenged to examine traditional production practices in order to improve product quality while limiting environmental impact. A recent focus on both the positive and negative effects of nitrogen applications has researchers across ...

  • New plant protein discoveries could ease global food and fuel demands

    New discoveries of the way plants transport important substances across their biological membranes to resist toxic metals and pests, increase salt and drought tolerance, control water loss and store sugar can have profound implications for increasing the supply of food and energy for our rapidly growing global population. That’s the conclusion of 12 leading plant biologists from around the ...

  • How to feed the world without destroying the planet

    By 2050, there will be another two to three billion people on Earth, and the planet's population will consume twice as much food as now. For 50 years farmland has grown at the cost of natural habitat and biodiversity, and already more than two-thirds of agricultural land is either in use or protected. As a ...

  • FAO urges end of malnutrition as priority

    Denouncing the huge social and economic costs of malnutrition, FAO Director-General José Graziano da Silva today called for resolute efforts to eradicate malnutrition as well as hunger from around the world. In a recorded statement marking the launch of FAO's flagship annual publication The State of Food and Agriculture ...

  • Arcadia Biosciences and African Agricultural Technology Foundation collaborate on test planting of nitrogen use efficient rice

    Arcadia Biosciences, Inc., an agricultural technology company focused on developing technologies and products that benefit the environment and human health, and the African Agricultural Technology Foundation (AATF) today announced the planting of the first field trial of Nitrogen Use Efficient (NUE) rice in Africa. The NUE rice field trial is the result of more than five years of collaboration ...

  • Keeping oilseed rape on track with a nutritional boost

    A nutritional boost to stimulate root development and provide for oilseed rape’s additional nutrition needs, will help maintain health and reliance in oilseed rape crops this spring. Despite the losses to flea beetle and drought, particularly in East Anglia, many oilseed rape crops have made a decent start. However, signs of disease pressure are already ...

  • Asia and the Pacific must increase food production to meet future demand

    Governments in Asia and the Pacific should take some major, fundamental decisions – and soon – about ways to increase their food production and address undernourishment, FAO has warned. The warning comes as nearly 40 FAO member countries gathered in the Mongolian capital for the 32nd FAO Regional Conference for Asia and the Pacific to examine the state of food and agriculture in the ...

  • Sustainable phosphorus use — evaluating past patterns to inform future management

    Recycling waste from farming and mining could help improve the sustainable use of phosphorus, a recent study suggests. The study traced the stocks and flows of phosphorus over a 50 year period to reveal changing patterns of global phosphorus use. The results can be used to develop the sustainable management of phosphorus — a finite and critical resource — in the future. ...
