When to check your satellite crop maps through the Pakistani cropping year — a month-by-month guide for wheat, rice, cotton, sugarcane and maize growers.
An honest comparison of free Sentinel-2 NDVI, drone mapping, and commercial satellite subscriptions — cost, resolution, revisit, and which farms actually need which.
NDVI is powerful but not infallible. Soil background, saturation, cloud shadows, weeds and more — eight situations where the map misleads and how to recognize each one.
Seven ways to connect NDVI patterns with field inspections, records and follow-up, with clear limits on what the map can establish.
Why your field gets a new satellite image every 5 days in theory but sometimes waits weeks in practice — understanding Sentinel-2 revisit cycles, cloud cover, and image quality.
Read NDVI in the context of wheat, rice, cotton and maize growth stages, without treating fixed values as a diagnosis.
NDVI explained in plain language: what the colors mean, how satellites measure crop health, and how to use a free NDVI map to make better decisions on your farm.
