  • 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 ...

  • 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 ...

  • Gas analysis workshop focuses on FTIR versatility

    Gasmet Technologies, the manufacturer of FTIR gas analyzers, organised a meeting in Lisbon, immediately prior to the CEM 2016 conference and exhibition in May, to provide delegates with an insight into the wide variety of applications for which FTIR technology is employed. The measurement of greenhouse gases (GHGs) was a particular focus for the event, with presentations from a number ...

  • 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 ...

  • 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. ...

  • ASTM D7758 - 11 Standard Practice for Passive Soil Gas Sampling in the Vadose Zone for Source Identification, Spatial Variability Assessment, Monitoring, and Vapor Intrusion Evaluations

    Passive soil gas samplers are a minimally invasive, easy-to-use technique in the field for identifying VOCs and SVOCs in the vadose zone. Similar to active soil gas and other field screening techniques, the simplicity and low cost of passive samplers enables them to be applied in large numbers, facilitating detailed mapping of contamination across a site, for the purpose ...

  • New analysis of energy and environmental performance of biofuels

    New research identifies important influences on the energy and environmental performance of biofuels made from agricultural crops. Type of land use change, type of biofuel crop and the by-products from the conversion process all influence performance. The benefits of introducing biofuels in the transport sector or as feedstock in the chemical industry are widely debated. Research has produced ...

  • On-site analysis of cannabis potency using Infrared spectroscopy

    Cannabis is increasingly being recognised for its therapeutic value. This has led to a reduction in its regulation, and even its legalisation, by many different governments. As cannabis production becomes legalised and regulated it is important that manufacturers can assess the chemical content and potency of their plants. The value of cannabis in the control of pain, spasm and a range of ...
