“Space-Age Farming: The 2025 Guide to Satellites That Spot Crop Stress, Soil Moisture & Yields—Almost in Real Time”
Expert soundbites 1) What satellite crop monitoring actually measures Plant status (optical & thermal):Multispectral imagers (Sentinel‑2, Landsat, PlanetScope) quantify greenness (NDVI/EVI), chlorophyll (red‑edge indices), and canopy water (NDWI/NDMI), proxies for vigor and stress. Sentinel‑2’s unique red‑edge bands (705–783 nm) sharpen sensitivity to chlorophyll
