Farmers increasingly rely on satellite imagery to monitor crop health across large fields without walking every row by hand. Multispectral sensors capture light reflected from plants at wavelengths invisible to the human eye, revealing stress from drought or disease days before visible symptoms appear. This early detection allows targeted irrigation or pesticide application only where needed, reducing water and chemical use compared to blanket treatment of entire fields. However, satellite data can be delayed by cloud cover, sometimes leaving farmers without updated images for over a week during rainy seasons. Smaller farms have been slower to adopt the technology, partly due to subscription costs and partly because imagery resolution is sometimes too coarse to distinguish individual plant clusters on modest plot sizes.
