Spectroscopy in Agriculture

Pressure of competition, decreasing available land for agriculture and last not least an increasing world population are driving forces for innovation in the agricultural sector. Modern testing methods of grow lights and improved grading and sorting methods are important factors to help improve crop yields.

Spectroscopy can play a vital role here. Learn about some agriculture spectroscopy application examples listed below.

Many fruits and vegetables can be graded and sorted by their color. Depending on the species often more accurate results can be achieved by assessing the spectral power distribution in the visible or near-infrared range.

During quality control of wine and whiskey it is needed to assess the alcohol content (proof number) and the color. By measuring the spectrum in the range from 380 nm to 1100 nm the color is determined in the visible range from 380 nm to 780 nm, while the alcohol content can be determined due the alcohol peak which appears around 907 nm in the absorbance spectrum.
