  • Nitrogen fertiliser `could prevent locust swarms`

    A surprising finding promises a cheap and environmentally friendly way of controlling locust swarms, a major plague that devastates crops around the world. Land erosion caused by heavy livestock grazing promotes ...

  • Fertiliser Storage Tanks and the Latest ADAS Farming Report

    The latest arable crop report from the Agricultural Development and Advisory Service (ADAS) was recently published, revealing that winter drilled crops were in good condition at the end of March. It also reveals that winter wheat crops were in good condition at the end of the month with typical crops at the end of late tillering stage. The control of black-grass and broadleaved weeds was good, ...

  • Comparing N2O emissions from organic and mineral fertilisers

    A recent study compares the effects of organic, 'natural' fertilisers, such as compost, with mineral, synthetic fertilisers, such as urea, on N2O emissions from Mediterranean soil. It suggests that there is little difference between the fertilisers, but that pig slurry offers the best overall balance in terms of emissions and crop yield. Nitrous oxide (N2O) is a powerful greenhouse gas (GHG). ...

  • Household compost as good for soil as conventional fertilisers, say EU researchers

    Since 2005, conventional disposal of organic waste has been prohibited in Sweden. Instead, this waste is incinerated or separated at source, processed (composted or anaerobically digested) and recycled as fertiliser on crop land. A new study has investigated the use of organic waste from different sources as a fertiliser and found that residue from biogas production is an effective fertiliser. ...

  • Mysteries of soil and nitrogen to be probed at Jamestown

    Making better use of soil moisture and nitrogen will be a major focus of the Grains Research and Development Corporation (GRDC) Update at Jamestown on August 19. GRDC Southern Regional Panel chair David Shannon said improving efficiencies in the use of moisture and nutrients was an important investment for the GRDC and keenly sought by growers in South Australia’s Mid North. “While the ...

  • Nutrient levels on the decline in many Estonian rivers

    A new study has analysed the impact of industrial and agricultural changes on nutrients in Estonian rivers. The results indicated that there were significant reductions in nitrogen in one third of the sites, significant reductions in phosphorus in a quarter of sites and significant reductions in both nutrients in nearly a tenth of sites. High levels of nutrients, such as nitrogen and phosphorus, ...

  • Rising CO2 levels likely to have impact on soil, says EU

    One issue of concern is the relationship between above ground (e.g. by trees) and below ground (e.g. by soil microbes) carbon cycling. Soil fertility appears to play an important role in this process as higher CO2 levels lead to greater competition between microbes and trees for soil nutrients, according to new research.  Soils are an important sink for carbon and understanding how microbes that ...

  • China launches rural pollution study

    The Chinese government has pledged funds to carry out the country's first survey of pollution sources in rural areas, according to state media. Zhang Fengtong, a senior official in the Ministry of Agriculture, told a press conference that the central government has allocated 230m yuan (US$31m) to the survey, which is set to get underway next year. The research will focus on animal, crop and fish ...

  • Potentially harmful effects of nanomaterials on soybean crops

    A new study has examined contamination of fully grown soybean plants by two nanomaterials – nano-cerium oxide and nano-zinc oxide. The results could be concerning, as they indicate that the nanomaterials are absorbed by plants, possibly affecting growth, yield, and the fixation of nitrogen in soil, an important ecosytem service. With the rapid expansion of nanotechnology, there is ...

  • Strong focus on soils at Cummins GRDC Update

    Probing soil moisture and building soil carbon will be key topics explored at the Grains Research and Development Corporation (GRDC) Update at Cummins on August 11. GRDC Southern Regional Panel chair David Shannon said growers on the lower Eyre Peninsula often dealt with ‘difficult’ soils and were keen for information to assist them in managing their soils. “The lower Eyre Peninsula is a very ...

  • Protecting farmland biodiversity

    A new study describes the rate of loss in plant diversity in intensively farmed fields. The authors recommend that measures to protect biodiversity should focus on low-intensity farmland, due to difficulties associated with rebuilding lost biodiversity in intensively farmed land. Intensive agriculture is one of the main drivers of the decline in worldwide biodiversity. The rate of species ...

  • Is biochar the answer for ag?

    Scientists demonstrate that biochar, a type charcoal applied to soils in order to capture and store carbon, can reduce emissions of nitrous oxide, a potent greenhouse gas, and inorganic nitrogen runoff from agriculture settings. The finding will help develop strategies and technologies to reduce soil nitrous oxide emissions and reduce agriculture’s influence on climate change. A research ...

  • Preserve, promote, and utilise rich soil life

    Healthy soil life can contribute to sustainable agriculture which, in addition to ensuring a good yield, keeps diseases under control and generates carbon and nitrogen retention. That is what Prof. Gerlinde De Deyn, Professor holding a personal chair in Soil Ecology, asserted in her inaugural address at Wageningen University & Research on 18 May. Life underground is richer in species than ...

  • GM crops can thrive as climate warms

    Genetically engineering photosynthesis in plants could take advantage of rising global temperatures and increased levels of carbon dioxide, US scientists say. They believe this could achieve much higher yields on the same amount of land and help to stave off the prospect of widespread hunger as human populations increase. Researchers at ...
