SPAD Measurement of Watermelon Seedlings-Food Waste Compost Study

Caption

A University of Arkansas System Division of Agriculture researcher takes a SPAD meter measurement of watermelon plants during a study on food waste as a substrate. A SPAD measurement offers a quick, non-destructive reading of a plant's leaf "greenness," which estimates its relative chlorophyll content, indicating plant health and nitrogen levels for optimizing fertilizer use in agriculture and research.
