How NIR Supports Agricultural Analysis
Near-infrared spectroscopy measures how a sample absorbs or reflects NIR light. Agricultural materials often contain molecular bonds such as C-H, O-H, and N-H, which produce useful spectral information for composition and quality assessment.
NIR is commonly used for grain testing, feed analysis, forage assessment, seed quality checks, and process control in agricultural production. It can provide fast, non-destructive results that support decisions about storage, blending, pricing, processing, or quality control.
Accuracy depends on calibration quality and sample consistency. Moisture, particle size, temperature, variety, growing conditions, and sample presentation can all influence spectra. Reliable agricultural NIR methods should be validated for the crop, property, and measurement conditions being used.
