The drones would first apply herbicides to clear previously logged land of grasses and brush that would otherwise choke off young tree saplings. Spraying is currently done rather messily via helicopter, or through slow, laborious manual labor. DroneSeed’s drones can carry an 11-liter container of liquid and spot spray within two centimeters of GPS coordinates.
Loaded with a batch of seeds, the drones would then fly to specified sites and fire a seed into the ground at a rate of 350 feet per second (384 km/h) using compressed air. According to the company, a drone could plant up to 800 seeds per hour, compared to 800 seeds a human can plant in a day, covering an acre (0.4 ha) of forest in 1.5 hours on a full battery charge.
Forestry techniques … hmmmmm
