Indian cooperative IFFCO is launching a national campaign to promote the use of nano fertilisers, with plans to procure 2,500 agri-drones and train 5,000 rural entrepreneurs. The drones will be used to spray IFFCO's nano urea and nano di-ammonium phosphate products. The cooperative will also purchase 2,500 electric three-wheelers to transport the drones to farmers' fields. The campaign will also train rural entrepreneurs to use the drones for spraying nano fertilisers.
