We use Normalized Difference Vegetation Index (NDVI) to give farmers a clear picture of crop health. By analyzing how plants reflect light, NDVI maps reveal areas of strong growth versus zones that may need attention.
✅ High NDVI = dense, healthy vegetation 🌿
⚠️ Low NDVI = poor crop health, nutrient stress, or bare soil
🟥 Red / Orange (Very Low NDVI)
Bare soil, water bodies, or severely stressed crops.
Requires immediate investigation.
🟨 Yellow (Low NDVI)
Sparse or weak vegetation.
May indicate nutrient deficiencies, early stress, or uneven germination.
🟩 Light Green (Moderate NDVI)
Vegetation present but not at peak health.
Monitor closely; could need irrigation or fertilization.
🟩🌿 Dark Green (High NDVI)
Dense, healthy, and vigorous vegetation.
Indicates strong growth and optimal conditions.
How it’s applied:
Monitor crop growth across the entire field
Detect stress early for timely intervention
Guide corrective actions in low NDVI zones (fertilization, irrigation, pest management)
NDVI helps transform field observations into data-driven decisions, ensuring healthier crops and higher yields. 🌾
