  • Keeping a pulse on the soil

    Leaving behind stubble is not ideal when shaving, but it’s a good practice to leave behind crop “stubble” after harvest. According to soil scientist Frank Larney, crop residue anchors the soil against wind and water erosion. Avoiding bare soils is one part of a soil conservation package he and his research team demonstrate in a 12-year experiment growing pulses in southern ...

  • Cultivation affects pesticide–soil interactions

    Pesticides are often used to enhance crop production by killing unwanted animals or plants. Unfortunately, they can also negatively impact humans and environmental health. The degree of impact, in part, depends on the fate and behavior of pesticides in the environment. The latter is governed by complex interactions of pesticides with soil components. One such important interaction is sorption of ...

  • Using organic fertilizers could protect against climate change

    Studies show that soil fertilized with organic materials, such as compost, could increase the amount of stored carbon and potentially help slow down greenhouse emissions. Applying organic fertilizers, such as those resulting from composting, to agricultural land could increase the amount of carbon stored in these soils and contribute significantly to the reduction of greenhouse gas emissions, ...

  • Phosphorus-rich soils support larger invertebrates

    In a recent study, researchers have defined the relationship between soil conditions and nutrients with the health of soil ecosystems. The results suggest that organic grassland, rich in phosphorus, is supportive of large populations of bigger invertebrates. All living things are made up of chemical elements in certain proportions and the availability of these elements in the environment can ...

  • `We need a new approach for better soil`

    ‘Dutch agricultural soils are not future-proof’ was a widely accepted statement at the final meeting of the Public Private Partnership (PPP) Sustainable Soil. Breeders, chain partners, suppliers, the government and the science sector see a gradual deterioration in soil quality and are joining forces within the PPP to find a solution. “It isn’t a simple matter,” says ...

  • A model to measure soil health in the era of bioenergy

    One of the biggest threats to today’s farmlands is the loss of soil organic carbon (SOC) and soil organic matter (SOM) from poor land-management practices. The presence of these materials is essential as they do everything from providing plants with proper nutrients to filtering harmful chemical compounds to the prevention of soil erosion. Sustainable management practices for crop residues are ...

  • Glomalin is key to locking up soil carbon

    A soil constituent known as glomalin provides a secure vault for the world's soil carbon. That’s according to Kristine Nichols, a microbiologist at the Agricultural Research Service (ARS) Northern Great Plains Research Laboratory in Mandan, N.D. Glomalin is a sticky substance secreted by threadlike fungal structures called hyphae that funnel nutrients and water to plant roots. Glomalin acts like ...

  • 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 ...

  • Soil biodiversity: functions, threats and tools for policy makers
