  • Opportunities To Increase Phosphorus Efficiency

    Wednesday, October 19th, 2011

    A national review of phosphorus fertiliser use in Australian grazing systems has found that there are opportunities to close the ‘inefficiency gap’ and maintain high farm productivity.
    Three key areas of potential have been identified including:

    Developing new pasture plant varieties that can use phosphorus better, or grow better, in lower-phosphorus soils.
    Exploring new [...]

  • Banana compost could boost crop yields, a study finds

    Wednesday, October 19th, 2011

    Using old banana trees to make compost may help boost crop yields while cutting down water and fertiliser use, according to an Egyptian researcher.
    Banana-based fertiliser could cut about 20 per cent of the water used in irrigating maize and lead to better yields and improved soil properties — such as [...]

  • Does Converting Cow Manure To Electricity Pay Off?

    Wednesday, October 19th, 2011

    Because more and more farmers and communities are interested in generating renewable energy from farm waste, there is a growing need for information on the economic feasibility and sustainability of such programmes.
    Now, in a case study published in the Journal of Dairy Science, researchers at the University [...]

  • Carbon Credits From Restored Grasslands

    Monday, October 3rd, 2011

    Large swathes of the world’s grasslands are moderately to severely degraded — restoring them to a healthy state could remove gigatonnes of carbon from the atmosphere and improve resilience to climate change. So far, however, carbon crediting schemes that pay projects for reducing greenhouse gas (GHG) emissions and sequestering carbon have largely ignored agriculture, [...]
