In central China's Henan Province, the wheat harvest is about to begin. Over 56,000 square kilometers of wheat will be reaped from south to north. Farmers are working hard to ensure a good summer harvest. They are using drones, drip irrigation and sprinklers to water the crop and increase yields. Henan is one of the major grain production areas in China, producing a quarter of the country's wheat output, but recently a severe drought has gripped the province.
