so ive been doing manual scouting on our family farm for years, basically walking fields with my agronomist every couple weeks and its fine but were expanding and honestly 400+ acres of corn and soybeans is getting to be too much to cover properly on foot. been looking at using a drone for NDVI mapping and general crop health monitoring but im not sure where to start or if the cost makes sense at this scale.

we already have a mavic 3 that i use for general stuff but i know that wont cut it for serious multispectral work. been looking at the micasense altum-pt sensor mounted on a bigger platform but the price jump is significant. anyone running a setup like this on a mid-size operation and actually seeing ROI? or is this more of a large-scale commercial ag thing where the numbers make more sense

400 acres is honestly right at the tipping point where it starts making sense imo. we run about 600 acres of mixed crops and switched to a matrice 350 with a micasense redEdge-P about two seasons ago. the NDVI data is genuinely useful once you figure out how to actually interpret it and stop just staring at pretty colored maps. the first season we caught a drainage problem in the north field that was causing nitrogen deficiency in a pretty specific area and we would have missed it doing manual walks probably.

the software side is where it gets annoying though. processing flights through something like agisoft or even DJI terra takes time and you need to have a system for it or the data just piles up. if youre not gonna commit to actually using the outputs consistently then yeah the ROI gets fuzzy fast

not sure about the specific sensor stuff but my neighbor farms about 350 acres and hes just using a regular phantom 4 multispectral which is way cheaper entry point than the altum setup. he says its good enough for catching obvious stress patterns, maybe not the most precise thing out there but it gets the job done for his needs. might be worth looking at before going full commercial rig
