To accurately estimate vegetation health, it’s important to measure water content. Water stress negatively affects plant growth and health, cutting back on photosynthesis efficiency. In most cases, researchers look at water content on a leaf/variety basis. A portable field agricultural spectrometer like the PSR+ allows researchers to measure water content/stress in the field without affecting the sample. The PSR+ is a full range (350-2500nm) NIR field portable spectroradiometer with high resolution and high sensitivity for clear and accurate spectra. Using the PSR+, spectra are collected quickly, accurately and without sample preparation. The spectra can exhibit main water absorption features including the most pronounced at 1450nm and 1950nm.
