Normalized Difference Vegetation Index (NDVI)
The Normalized Difference Vegetation Index is a simple graphical indicator used to assess whether the target area contains live green vegetation or not based on remote sensing data.

NDVI is widely used in precision agriculture to monitor crop health, vegetation density, and growth stage progression. By analyzing how plants reflect specific light wavelengths, agronomists can identify areas of stress, nutrient deficiency, or pest infestations at an early stage.
Practical application involves variable rate application of fertilizers and crop monitoring during the entire growing season. This data-driven approach helps optimize input costs and increases the efficiency of field scouting operations, allowing managers to focus efforts on problematic areas.
Common mistakes include misinterpreting data without considering the specific crop phenology and soil moisture conditions. Another limitation to keep in mind is the saturation effect, where the index becomes less sensitive to biomass differences once the canopy reaches a high level of density.
