soil respiration measurement News

  • Even soil feels the heat

    Twenty years of field studies reveal that as the Earth has gotten warmer, plants and microbes in the soil have given off more carbon dioxide. So-called soil respiration has increased about one-tenth of 1 percent per year since 1989, according to an analysis of past studies in this week's issue of Nature. The scientists also calculated the total amount of carbon dioxide flowing from soils, which ...

  • Mapping Earth`s soil moisture with NASA

    Professor Dara Entekhabi from the Massachusetts Institute of Technology is to lead a science team designing a NASA satellite mission to collect global soil moisture measurements and other data seen as key to improving weather, flood and drought forecasts and predictions of agricultural productivity and climate change. At present, scientists have no network for gathering soil ...

  • Soil CO2 emissions may continue for longer than previously thought

    Current models of soil carbon suggest CO2 emissions caused by rising temperatures will decrease over time. However, a recent study, which deliberately warmed soil for ten years, found no evidence of such a decline. The results indicate that our understanding of soil carbon dynamics may need revisiting. Soil is one of the most important carbon stores in the world. Just 0.1 per cent of carbon ...

  • Study helps clarify role of soil microbes in global warming

    Current models of global climate change predict warmer temperatures will increase the rate that bacteria and other microbes decompose soil organic matter, a scenario that pumps even more heat-trapping carbon into the atmosphere. But a new study led by a University of Georgia researcher shows that while the rate of decomposition increases for a brief period in response to warmer temperatures, ...

  • Common soil bacteria could clean up nuclear contamination

    Researchers are studying some common soil bacteria that “inhale” toxic metals and “exhale” them in a non-toxic form. The bacteria might one day be used to clean up toxic chemicals left over from nuclear weapons production decades ago. Using a unique combination of microscopes, researchers at Ohio State University and their colleagues were able to glimpse how the Shewanella oneidensis bacterium ...


  • The Vaisala CARBOCAP®: Compact, Reliable, Accurate and Durable

    The Vaisala CARBOCAP® Carbon Dioxide Probe GMP343 is a compact field instrument designed for soil respiration measurements, other ecological measurements and various custom applications.The Vaisala CARBOCAP® Sensor is a silicon based, non-dispersive infrared (NDIR) sensor for the measurement of carbon dioxide. In the sensor a true dual-wavelength measurement is provided with a simple and ...


  • Macaulay Institute chooses Enviro Technology’s Picarro for their international research

    Leading Aberdeen based land-use research centre the Macaulay Institute has purchased two Picarro isotopic CO2 (Carbon Dioxide) analysers from Enviro Technology for its world-wide research programme. The analysers are being used for the Institute’s field campaigns, which look at the 13C isotope content of CO2 which leaves the soil surface. By measuring  the ...

  • Trade-offs in ecosystem services in Central and Eastern Europe

    Researchers have developed a new approach for identifying regions that are most suitable for expanding ecosystem services. This could be used to help inform spatial planning decisions. By modelling ecosystem services’ opportunity costs in relation to agricultural revenue, the study provides a map of suitable areas of ecosystem service expansion in Eastern Europe. Understanding where ...

  • Greenhouse Gas Benchmark of 400 Parts per Million reached and excceded

    For the first time since the U.S. National Oceanic and Atmospheric Administration began tracking carbon dioxide in the global atmosphere, the monthly global average concentration of this greenhouse gas surpassed 400 parts per million in March 2015, according to NOAA’s latest results. ...

  • Entsorga-Enteco 2009 – Focus on `Air Quality Control & Emissions Protection`: Mission `Clean Air` forges ahead

    Air quality control is one of the success stories of European environmental policy. Ever fewer air pollutants are being released into the atmosphere from power stations, waste incineration plants,industrial processes. But this is no reason to sitback. Environmental policy is still focussing above all on nitrogen compounds such as NOx and ammonia as well as particulate matter and ground-level ...
