Using a field spectroradiometer for wheat crop analysis
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 information 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-1100f is a handheld spectroradiometer with the following features:
- 320-1100nm 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
- 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.
