NIR spectroscopy is an excellent tool for evaluating soil properties.

The PSR-3500 full range, field portable spectroradiometer provides scientists and researchers with a relatively simple, non-destructive, reliable, fast and accurate method for measuring total carbon, inorganic carbon, organic matter, total nitrogen, mineralized nitrogen, clay, silt, sand, moisture, pH, cation exchange capacity (CEC), and much more. Lightweight and rugged, the PSR-3500 provides for soil analysis in the field to categorize soil/land changes over large or small areas.

Soil measurement applications can include:

  • Measuring topsoil fertility
  • Estimating erosion risks
  • Measuring hydraulic properties
  • Analyzing soil degradation
  • Soil mapping and monitoring
  • Crop monitoring during growth cycles
  • Measuring the presence, amount, and effect of fertilizer in the soil

    The PSR-3500 features:
    *
    Fast, full spectrum 350-2500nm measurement with just one scan
    *
    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
    *
    Superior signal-to-noise ratio with faster scan times and better reflectance measurement

    The PSR-3500 is equipped with the exclusive DARWin SP Data Analysis software package so you can take advantage of the following analysis features:
    *
    Automatically saves data as an ASCII file for easy use with  3rd party software -
    no pre-processing is necessary
    *
    Collect reference or target data with a single click
    *
    Display reflectance/transmittance data (percentage) or absorbance (logarithmic) versus wavelength
    *
    Single and multiple spectral plots available
    *
    Compare current scans against libraries
