Fertilizer Urea DAP Spreading
Works in wet paddy tractor cannot enter, 20ha/hr
Mission briefing
Fertilizer Urea DAP Spreading sits in the treatment stage of the crop cycle. It runs on a agras t40 spreader / xag p150 carrying granule spreader 50-70kg, and in Bihar the window is tillering, pi stage at a frequency of 2x. Expect roughly 20ha/hr per sortie, and stand the drone down outside the wind <8m/s envelope — flying past it wastes chemical and risks drift onto neighbouring plots. Readings are interpreted through NA, so the payload has to output those bands rather than plain RGB. Works in wet paddy tractor cannot enter, 20ha/hr On a easy-difficulty mission like this, the cost driver is not the drone — it is the number of return trips and the pilot hours around them, which is what the payback maths on the economics page turns on.
