Kolkata (West Bengal) [India], May 25: Every morning, across thousands of farms in India and Bangladesh, farmers receive an advisory that tells them precisely what their crop needs that day. Not a generic recommendation pulled from a government extension handbook. Not a broad seasonal guideline applicable to an entire district. A specific, contextual, data-driven instruction — calibrated to the soil under their feet, the crop stage in their field, the disease pressure building in their microclimate, and the weather pattern moving toward them in the next seventy-two hours.
