  • Monitoring groundwater, vapor & soil gas

    Monitoring shallow groundwater, vapor and soil gas up to 25 ft. below surface is simplified using Drive-Point Piezometer technology. There are three drive point piezometer tip options; where an airtight connection is most desirable, the 615C has a compression fitting for 1/4" ID tubing, ideal for ...

  • Soil Gas Analyzer CH4 CO2 NH3 H2O

    LGR’s new CH4/CO2/H2O/NH3 Analyzer reports measurements of ammonia, methane, carbon dioxide, water vapor simultaneously in a package that is compact, crushproof and travels anywhere. Small enough to be carried on-board aircraft (TSA approved size) and requiring less than 70 W, the analyzer offers new opportunities to quickly, reliably and accurately measure trace gas emissions anywhere. As ...

  • Gas sensors `see` through soil to analyze microbial interactions

    Rice University researchers have developed gas biosensors to “see” into soil and allow them to follow the behavior of the microbial communities within. In a study in the American Chemical Society’s journal Environmental Science and Technology, the Rice team described using genetically engineered bacteria that release ...

  • 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 ...

  • Rediscovering sound soil management

    At the same time that demand for food is soaring along with the world’s population, the soil’s ability to sustain and enhance agricultural productivity is becoming increasingly diminished and unreliable. Fortunately, it’s not too late to restore our soil resources. What it will take, say the editors and contributors to a new book, Soil Management: Building a Stable Base for ...

  • Gas Spill? Chill - Soil Vapor Extraction (SVE) system to alleviate high levels of gasoline vapors

    It's not often you get instant gratification. Unless you're in this bind: a 600-gallon gasoline spill due to vandalism that threatened a local municipal pump station in Oregon. As gas made its way along a sewer line trench, it infiltrated soil and below-ground infrastructure. A lost cause, right? Wrong. Enter BB&A Environmental, an RPI Group member. After ...

  • Los Gatos Research Now Offers Ten Ultraportable Analyzers for Soil Trace Gas Flux Measurements

    Los Gatos Research (LGR), the leader in precision trace gas analyzers, today announced that it has expanded the lower speed (up to 1 Hz) trace gas analyzer line to include as many as nine different Ultraportable trace gas analyzers with various combinations available in ten different products. This year's R&D 100 Award winning analyzer for NO2 (nitrogen dioxide) joins a series of 1 Hz ...

  • Smithsonian exhibition reveals impact of soil

    Starting on Saturday, October 2, visitors to The Durham Museum will enjoy a journey into the skin of the earth and explore the amazing world of soils in the new exhibition, Dig It! The Secrets of Soil. Completely familiar yet largely unknown, soils help sustain virtually every form of life on Earth. Still, it is said that we know more about the dark side of the moon than we do about the Earth ...

  • Landfill cover soil methane oxidation underestimated

    Landfilled waste decomposes in the absence of oxygen and results in the production of methane. Landfills are classified as the second-largest human-made source of CH4 in the U.S. Additionally, landfill gas contains numerous non-methane hydrocarbons that are either volatilized directly from waste materials or produced through biochemical reactions during waste degradation. Microbial methane ...

  • Sophisticated soil analysis for improved land use

    Soil variation occurs across multiple geographic scales ranging from vast climatic regions of the Earth to a 50 acre farm field to the molecular world of soil nano-particles in a pinch of soil. For example, in a forest or an agricultural field, soil properties vary from the summit of a hill down to the base. Within a single soil aggregate that may be less than a quarter inch in diameter, there ...

  • Environment Agency Updates Soil Test Policy

    Ashtead Technology Rentals reports a rapid rise in rentals of their portable contaminated land assessment instruments following a recent amendment to UK Environment Agency policy. The qualification requirements for chemical test data on contaminated soils now acknowledges that portable measuring instruments can both improve the quality of contaminated land assessment and reduce costs. Ashtead ...

  • Safety measures proposed for soil fumigant pesticides

    New draft safety measures for soil fumigant pesticides proposed by the US Environmental Protection Agency last week require that users of these chemicals submit written, site-specific fumigant management plans before fumigations begin. All soil fumigant products will be classified as restricted-use pesticides, to ensure that only specially trained individuals can apply and oversee fumigant ...

  • New edition of soil analysis `bible` released

    “It’s been almost 20 years since an earlier ‘Soil Chemical Methods’ book was published in the Australian Soil and Land Survey Handbook series,” said lead author, former Principal Scientist with the Queensland Department of Environment and Resource Management (QDERM) Dr George Rayment. The new book, written by George Rayment and David Lyons (also from QDERM) and ...

  • Cattle can help restore degraded soil

    Agriculture Research Service has tested cattle grazing on degraded soil to determine if the activity would have any effect on restoring depleted nutrients. During a 12 year period, 18 paddocks were used to monitor the soils response to different land management practices. In the end, the paddocks with medium to heavy grazing proved to be the best way to sequester nitrogen and carbon in the soil. ...

  • Help students think like soil scientists

    Emphasizing cross-disciplinary concepts in teaching soil science courses, such as mass-volume relationships, can help undergraduates learn real-world, problem-solving skills that are crucial to their success in soil science careers. Drs. Josh Heitman and Michael Vepraskas, North Carolina State University Soil Science Department, highlighted this need for quantitative measurement skills in an ...

  • New portable FTIR Gas Analyser detects almost any gas

    Gasmet Technologies Oy (Finland) has announced the launch of the DX4040 – a portable FTIR gas analyser that enables the field measurement of literally thousands of gases.
