  • Can simple measures of labile soil organic matter predict corn performance?

    Organic matter is important for soil health and crop productivity. While an indicator of soil quality, a lot of organic matter is in extremely stable forms, and the nutrients in such forms are difficult for plants to use. The active, labile fraction, however, is a modest but important part of the organic matter. “The labile fraction is small – usually less than 20 or even 10 percent, ...

  • Strategic organic matter throughput helps to build soil carbon and boost crop yields

    Potential improvement in crop yields and reduced greenhouse gas emissions were among the benefits of increased soil organic matter throughput according to the findings of a project funded by growers and the Australian Government through the Grains Research and Development Corporation (GRDC) and the Victorian Department of Primary Industries (DPI). The relationships between organic matter inputs ...

  • 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 ...

  • Safeguarding our soils for the future

    Measures to protect and improve our soil to meet rising demand for food and to combat climate change have been unveiled by Environment Secretary Hilary Benn. England’s soil has suffered over the last 200 years from the impacts of intensive farming and industrial pollution, and today is under threat from erosion by wind and rain, a loss of organic matter and nutrients, and pressure for ...

  • Easing the soil’s temperature

    Soil characteristics like organic matter content and moisture play a vital role in helping plants flourish. It turns out that soil temperature is just as important. Every plant needs a certain soil temperature to thrive. If the temperature changes too quickly, plants won’t do well. Their seeds won’t germinate or their roots will die. “Most plants are sensitive to extreme ...

  • 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 ...

  • 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 ...

  • Select groundcover management systems found viable for organically managed apple orchard

    Determining and implementing orchard management practices that can improve soil organic matter is one of the primary goals of the USDA's National Organic Program. For producers in the southeastern United States, where interest in small-scale and organically managed orchards is growing, the challenge can be finding combinations of groundcover management systems and organic nutrient sources that ...

  • ARS explores ways to keep carbon in the soil

    Agricultural Research Service (ARS) scientists are testing out alternative ways of tilling the soil and rotating crops to see if they can help wheat farmers in Oregon sequester more carbon in the soil and reduce greenhouse gas emissions. Soil organic carbon plays a major role in how well a cultivated field holds moisture, provides nutrients and remains productive. That can be a problem in ...

  • Cattle contribute to greenhouse gas production in soil

    As harmless as cattle may seem, they are regarded as a threat to the climate. Through their digestion they produce the green house gas methane, which they expel continuously. Scientists from the Institute of Soil Ecology of the GSF – National Research Centre for Environment and Health in Neuherberg, Germany and Czech colleagues at the Budwies Academy of Sciences have shown that cattle can boost ...

  • Crop residues provide valuable protection for soil

    Removing wheat and sorghum crop residue after harvest, such as stalks, stubble and leaves, may cause more harm than good according to new research. Results indicate that removing residue can increase nutrient and sediment levels in water runoff, and decrease organic carbon stored in the soil. Crop residue left after harvest performs several ecosystem services. In particular it protects the soil ...
