We will be using the Photosynq to evaluate different zones of a farmer's field. The results will be compared to yield data at harvest and aerial photos from throughout the growing season.
- Chlorophyll content (SPAD) II
REQUIREMENTS: Firmware v0.39 or v0.40. Measures transmission at 940nm and 650nm in order to determine the 'greenness' of a leaf, an indicator of chlorophyll content and nitrogen content. The 940 is used to account for leaf thickness. Improvements over Chlorophyll content (SPAD): - performs 3 different spads at 3 intensities for thin and thick leaves - auto-chooses appropriate intensity - is calibrated to a Minolta SPAD device from factory
