Analyzing Wheat Crop Health with a Field Spectroradiometer

Measurements of a wheat canopy taken with a field spectroradiometer like the PSR-1100 or PSR-1100F, can provide data on protein, lignin, cellulose, water, sugar, starch, chlorophyll content, and more. With these spectroradiomers, spectral reflectance measurements provide insights for physiological wheat trait selection, estimated crop yield for agricultural planning, monitoring of crop stress, irrigation and nutrient planning, and potential early diagnosis and control of crop pests.

With the PSR-1100 and PSR-1100F, NIR spectroscopy is fast, easy-to-use, and completely harmless to the crop sample. Spectra scanned in the field can be analyzed to:

•    Determine the photosynthetic area and activity of a wheat canopy
•    Measure health and growth
•    Estimate potential grain yield
•    Monitor plant stress through measurement of chlorophyll content
•    Check for nutrient deficiencies and over-fertilization
•    Check for moisture content and fine-tune irrigation strategies

The PSR-1100 offers a fixed 4° FOV optic while the PSR-1100F provides a detachable fiber optic cable for connection to a wide array of FOV lenses, irradiance diffusers, sample probes and more. They both feature:

•    320-1100nm spectral range
•    Keypad and LCD display—stores 2500 scans without a computer
•    One-touch operation with auto-exposure and auto-shutter
•    Compact, lightweight, handheld unit—less than four pounds
•    Snap-in rechargeable battery
•    Built-in laser targeting
•    Easy-to-use DARWin SP Data Acquisition software saves scans as ASCII files for use with third party software, including chemometrics, without pre-processing
