Press Release: Measuring Soil Organic Carbon in Situ with a Field Spectroradiometer

The PSR™+ field, portable spectroradiometer from SPECTRAL EVOLUTION provides fast, affordable analysis of soil organic carbon.

Lawrence, MA – July 27, 2017 – Measuring soil organic carbon provides critical information on soil characteristics including color, nutrient capacity (cation and anion exchange capacity), nutrient stability and turnover, water relationships, aeration, and cultivation. Measuring soil organic carbon with a field spectroradiometer like the Spectral Evolution PSR+ can provide critical information on soil fertility, aggregate stability, and
the exchange of CO2 with the atmosphere – all important for environmental monitoring and precision agriculture.

TOC is the main source of energy for soil microorganisms and plants, and functions as a trigger for nutrient availability through mineralization. In a typical soil spectra, soil organic carbon features would be seen at 1100, 1600, 1700-1800, 2000, and 2200-2400nm. The PSR+ has the highest resolution and sensitivity available in a field spectroradiometer, giving you an edge in measuring and analyzing soil.

The PSR+ is specifically designed for the field with rugged and reliable construction. It offers a wide range of direct attach FOV lenses as well as swappable fiber optic mount options for use with a handheld contact probe or a benchtop probe with compactor for easy soil sample loading. The fiber mount with contact probe is ideal for taking scans of vertical and horizontal layers in a soil pit. The PSR+ features:

  • Fast, full spectum 350-2500nm measurement with just one scan
  • Highest resolution and sensitivity in a portable instrument
  • Autoshutter, autoexposure, and auto-dark correction before each new scan for easy, one-touch operation
  • Small and lightweight with rechargeable Li-ion batteries for field operation – half the weight of competitive instruments
  • Reliable field performance with an all photodiode array platform and no moving gratings that can jam unexpectedly
  • Single user operation with optional rugged handheld microcomputer that provides a sunlight readable screen plus the ability to tag spectra with GPS, digital camera images, and audio notes
  • Standalone operation with 1,000 scan storage
  • DARWin™ SP Data Acquisition software automatically saves spectra and data to ASCII file format for use with other analysis software
  • Optional EZ-ID™ sample identification software with Custom Library Builder module to create your own soil reference library from known samples
