Soil Electric Conductivity, separation 1m
More sensitivity in late growth stage (high LAI). It tries to correct for soil background signals and atmospheric influences.
Extra Units of Measure for EU BigDataGrapes, based on QUDT 2.0
Very high Chlorophyll & Nitrogen sensitivity. Canopy Chlorophyll & Nitrogen contents can be derived for a wide range of crops (e.g. potato, soybean, maize) and grassland. This can be used to plan harvests.

A Brix degree equals 1 gram of sucrose per 100 grams of solution. This is a convenience unit equal to percent, but applicable only to this specific compound
Reduced soil background effects. SAVI tries to correct for bare soil areas in the field. Therefore it is interesting in sparse vegetation canopies or early growing stages.
Antioxidant activity: Spectrophotometric method of antioxidant capacity using DPPH assay measuring density of trolox equivalent" ;
Soil Electric Conductivity, separation 0.5m
Total microbial count: Measurement of TPC with classic development of micro-organism in petri-dishes
ratio: number of judges who detected a specific aroma divied by all judges number

Associated with chlorophyll and nitrogen content. This index can be found in precision agriculture applications. Crops with a low Nitrogen content can have a high carotenoid to chlorophyll ratio. Using the red and blue spectral bands, NPCRI captures the information needed to quantify chlorophyll and Nitrogen.
Normalized Pigment Chlorophyll Ratio Index
The Red Edge Indices are designed to estimate chlorophyll content in the canopy. More sensitivity in vegetation with high LAI. Less sensitivity to open water.
Sensitive to Vegetation water content & water stress. Allows drought monitoring. NDWI is less sensitive to atmospheric effects than NDVI.
2,2-diphenyl-1-picrylhydrazyl, a common anti-oxidant assay

Vegetation vitality. NDVI correlates with the amount of leaf area (LAI) of active, healthy, green vegetation. Advantage: The most widely used vegetation index. Disadvantage: It saturates at high LAI levels and therefore shows limited variation in dense fields with high biomass. It minimizes topographic effects. Negative values of NDVI (values approaching -1) typically correspond to open water. Values around zero (-0.1 to 0.1) generally correspond to bare soil, barren areas of rock, sand, or snow. Low, positive values represent low or sparse vegetation (approximately 0.2 to 0.4), while high values indicate dense vegetation (values approaching 1).
Gram per liter is a convenience unit, numerically the same as Kilogram per Cubic Meter
