NIR spectroscopy can be used to provide critical information on
wheat crop health and growth in the field. Measurements taken of a
wheat canopy during different growth stages can reveal data on
protein, lignin, cellulose, water, sugar, starch, chlorophyll content
and more.

Using a
PSR-1100f in the field, a researcher can gain in formation for
wheat trait selection, estimation of crop yield, crop stress, and
identification and control of crop pests.

An NIR agricultural spectroradiometer provides fast, easy-to-use and
non-destructive methods for characterizing wheat samples. A
researcher can analyze the spectra data collected to:
  • Determine the photosynthetic activity of a crop canopy
  • Measure crop health and growth at various stages
  • Estimate potential grain yield
  • Monitor plant stress through chlorophyll content measurement
  • Check for nutrient deficiencies or over fertilization
  • Check moisture content and fine-tune irrigation practices

The PSR-1100
f is a handheld spectroradiometer with the following
features:
  • 320-1100 nm spectral range
  • Rugged anodized aluminum construction for field reliability
  • High resolution and high sensitivity
  • Keypad, LCD display, and on-board storage for 2500 scans
  • One-touch operation with auto-exposure, auto-dark current,
    and auto-shutter
  • Compact and lightweight unit
  • Snap-in rechargeable battery
  • Built-in laser targeting
  • Easy to use DARWin SP Data Acquisition software that saves
    scans as ASCII files for further analysis with other software
    packages
  • Access within DARWin SP to 19 vegetation indices

The PSR-1100f includes a detachable fiber optic cable with a
wide range of optional FOV lenses and irradiance diffuser.
DARWin SP Data Aquisition software includes access to 19
vegetation indices via pull-down menus. The indices include NDVI,
ARVI, SR, and more.
