The client is using agricultural drones to fertilize rice paddies. Each drone can spread 70 kg of fertilizer per application, totaling approximately 10 tons per day, covering an area of ​​300-400mu (about 20-20 hectares), equivalent to the daily workload of more than 50 workers. This method not only solves the problem of farmers finding it difficult to recruit workers during the spring planting season, but also improves the management efficiency of rice cultivation through precision fertilization, reducing labor costs.
