SPAD 502 Chlorophyll Meter, with Data Logger
Announcement posted by John Morris Group 18 May 2015
Reduce your risk of yield-limiting deficiencies or costly over-fertilising. The SPAD 502 Plus quantifies subtle changes or trends in plant health long before it is visible to the human eye. The SPAD 502 Plus instantly measures the chlorophyll content or "greenness" of your plant. Nitrogen (N) is a key element in chlorophyll production; hence, chlorophyll can be used as an index to gauge the nitrogen status of a plant.
Non-invasive measurements are completed by simply clamping the meter over leafy tissue. An indexed chlorophyll content reading is displayed in less than 2 seconds. Assess nitrogen needs by comparing your in-field SPAD readings to university guidelines. The Konica Minolta SPAD 502Plus can be purchased with or without a integrated data logger plus a GPS-compatible data logger. Store up to 4096 measurements (1488 with GPS coordinates) for easy analysis.
Assess nitrogen needs by comparing in-field SPAD readings university guidelines or adequately fertilised check or reference strips. Research shows a strong correlation between SPAD measurements and leaf N content. You benefit by increasing reducing costly under/overfertilising, increasing N-efficiency and producing healthier, higher-yield crops. Research has proved a strong correlation between SPAD measurement and N leaf content.
