so ive been running a small operation, about 400 acres of corn and soybeans, and my agronomist keeps pushing me to look into drone scouting instead of walking fields every week. i finally borrowed a friends mavic 3 multispectral last season just to try it out and honestly the NDVI data was kind of eye opening ? caught a nitrogen deficiency in one section way earlier than i would have on foot.

but heres my thing, i dont know if its worth the investment for someone at my scale. i keep seeing the DJI Agras stuff and the senseFly fixed wings being thrown around on here but those are more for the big guys it seems like. im more interested in whether a standard multispectral setup like the Mavic 3M or maybe an Autel with a separate sensor makes more sense if youre not doing thousands of acres. anyone actually running something like this on a smaller farm or are you all contract operators working bigger land?

also curious how you handle the data processing side, like are you using Pix4Dfields or something else. that part feels like it could get expensive fast

400 acres is actually a pretty decent sized for a multispectral setup to make sense, id say the break-even for owning vs hiring a service is somewhere around 200-300 acres depending on crop value. soybeans are thinner margin so maybe lean toward corn fields for priority scouting.

i run a Mavic 3M on about 600 acres mixed corn and wheat and the workflow is manageable. Pix4Dfields is what i use and honestly its not that bad once youre used to it, the subscription stings a little but i process maybe 2-3 flights a week during peak season so it pays out. the real time NDVI coloring in the app is actually good enough for basic decisions without even doing the full processing sometimes.

the thing nobody tells you is the time investment for learning to actually interpret the data correctly. the maps are easy to generate but acting on them without screwing up is a different skill, spent a whole summer figuring that part out the hard way

yeah i had the same question like a year ago and just went for it, no regrets. the mavic 3 multispectral is honestly fine for what youre describing. fixed wings are kind of overkill unless you need to cover like 2000+ acres in one shot or are doing contract work where time is money per acre.

one thing ? dont sleep on DroneDeploy if youre already comfortable with subscription tools, their field health stuff has gotten pretty solid and the mobile app makes ground truthing way easier when youre actually walking problem areas you spotted from the data
