  • Nitrogen applied

    Combating soil erosion is a primary concern for agricultural producers in the United States, and many have incorporated conservation tillage systems in their effort to maintain a profitable crop output. Cover crops are an important tool in this cycle, and while it is known that using nitrogen fertilizers can increase these crops biomass, the resulting levels of nitrogen for the following cash ...

  • Soil nitrogen increased through greater plant biodiversity

    Increased plant biodiversity improves grassland soil quality by boosting its nitrogen levels, even in the absence of nitrogen-fixing plants, recent research has found. Previous research has shown that grasslands with higher biodiversity had higher levels of carbon and nitrogen. However, in the case of nitrogen it has been suggested that this was purely a result of increased numbers of ...

  • Bringing nitrogen out to pasture

    Cows in Brazil might start bellowing "leguuume" rather than "moo." That's because Jose Dubeux Jr. wants to plant more legume trees in cow pastures. Dubeux is an assistant professor of Agronomy at North Florida Research & Education Center. Growing up, Dubeux spent a lot of time on his grandparents' farm in Brazil. There he developed a passion for livestock operations and the grasslands on ...

  • Straw residue helps keep nitrogen on the farm

    Scientists are exploring ways to reduce non-point pollution from agriculture. A new study finds that using straw residue in conjunction with legume cover crops reduces leaching of nitrogen into waterways, but may lower economic return. Agriculture is the largest source of nitrogen non-point pollution to waterways in the United States, flowing into streams and rivers via erosion from farmlands, or ...

  • 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 ...

  • Nitrogen use by warm-season grasses for biomass production

    Perennial, warm-season grasses are being evaluated as potential renewable energy crops. These species are well-suited for the production of biomass for energy applications because they utilize C4 photosynthesis and are perennial. Grasses that employ the C4 photosynthetic pathway use water, nitrogen (N), and solar radiation more efficiently than plants having the C3 pathway, and therefore are ...

  • A little nitrogen can go a long way

    Varying the rate of crop production inputs such as fertilizer and seed makes intuitive sense, as farmers have long observed differences in crop yield in various areas of a single field. The availability of spatial yield information from combines equipped with yield monitors has provided a good resource for improved management. So, optimizing inputs to match yield potential of different areas ...

  • Arcadia Biosciences Receives Chinese Patent for Key Nitrogen Use Efficiency Technology

    Arcadia Biosciences, Inc., an agricultural technology company focused on developing technologies and products that benefit the environment and human health, today announced that the company has been granted a key patent for its Nitrogen Use Efficiency (NUE) technology from the State Intellectual Property Office of China. Issuance of this patent is an important ...

  • Nitrogen fixation helps double some African farm yields

    A large-scale research and development project has shown that giving farmers resources and advice on nitrogen fixation through legume plants can double yields and boost incomes in Africa. But not all farmers are benefiting from this practice due to a lack of access to inputs, such as fertilisers says Ken Giller, the leader of the ...

  • Using Liquid Manure to Fertilize Wheat? Consider Timing, Nitrogen Content

    Liquid livestock manure can be a great option as a spring top-dress fertilizer for wheat fields if applied during the appropriate window of time and if it has the right amount of nitrogen, according to research conducted by the College of Food, Agricultural, and Environmental Sciences at The Ohio State University. In a report published in the latest issue of the college’s  ...

  • Global Biofertilizers Market Forecast to 2017 - Nitrogen Fixing, Phosphate Solubilizing, Potash Mobilizing

    Biofertilizers are preparations containing living cells or latent cells of efficient strains of micro-organisms which helps the crop plants in uptake of nutrients from the soil. Once applied the biofertilizers quickens the microbial activities in the soil. These microorganisms generate plant nutrients like nitrogen and phosphorous through the activities in the soil or rhizosphere which is ...

  • Before spring planting expert says, `Dig a little. Learn a lot.`

    As spring temperatures go up, it's an excellent time for farmers, ranchers and gardeners to focus their attention down to the soil below them. A spring check-up of your soil's health gives clues of your ground's ability to feed plants, hold water, capture carbon and more.  No fancy equipment required. Just grab a spade or shovel and prepare your senses todig a little and learn a lot. "It ...

  • Plant and soil science conference emphasizes food, energy and environmental security

    A conference is coming to Long Beach Oct. 31 to Nov. 3 that presents the latest research in plant and soil science, emphasizing the security of food, energy and the environment in the next green revolution.

  • Increasing aridity will disrupt soil nutrient cycles in global drylands

    The drying of soils under global warming could disrupt the balance of nutrients in large areas of the Earth’s land surface, according to new research. The study focused on ‘drylands’ – arid areas with low levels of rainfall – which support over 38% of the world’s population. Such nutrient imbalances could diminish the provision of ecosystem services, such as ...

  • Microbe diet key to carbon dioxide release

    As microbes in the soil break down fallen plant matter, a diet 'balanced' in nutrients appears to help control soil fertility and the normal release of the greenhouse gas carbon dioxide into the atmosphere. When plants drop their leaves, stems and twigs, this organic matter slowly becomes part of the soil as a result of decomposition, which is facilitated by bacteria and other microbes. This ...

  • Signs of recovery in polluted Czech forests

    Pollution has had a significant impact on European forests, where it disrupts many natural processes. Forests in Central Europe are among the most severely affected by pollution worldwide. New research1 from the Czech Republic suggests that attempts to cut sulfur-based pollution (such as acid rain) could also be important in a longer-term reduction of nitrate output from forest watersheds as ...
