Real-time measurements of plant stress and growth rate are important components of ecosystem analysis and precision agriculture. Apogee Instruments, Inc. in Logan, UT, has refined the use of the StellarNet spectroradiometer to image plants to predict growth rate and identify stress. Apogee Instruments distributes the StellarNet spectroradiometer and provides custom software and customer support for these applications. Spectroradiometer measurements allow us to determine plant growth rate, percent ground cover, nitrogen status, and water stress.
