Precision Scouting Plans Built for Kansas Farms

You already know herbicide costs are climbing and weed resistance is getting worse every season. What if one drone flight could show you exactly where to spray — and where you can skip? That is what precision weed scouting does. You save money, protect your soil, and get better weed control on the same pass.
Why Citadel Drones
Stop Spraying Blind — Scout Smarter with AI
Cut Herbicide Costs 40–60%
University research shows drone-guided precision spraying saves farmers $10–$15 per acre on post-emergence herbicides. Your scouting fee pays for itself on the first pass.
Prescription Maps Your Sprayer Loads Directly
No more guessing. You get a shapefile prescription map showing exactly where to apply — compatible with your variable-rate equipment.
Variable-Rate Fertilizer Mapping — Coming Soon
With fertilizer costs rising fast, the same NDVI drone data that maps your weeds can pinpoint exactly where your crops need nitrogen — and where they don't. Ask us about early access.
Proven Results
Farmers Across the Midwest Are Already Saving Thousands
University field trials and real-world data from over 5 million acres show precision weed scouting cuts herbicide use 40–76% with zero yield loss. At $6–$10/acre for scouting, most farmers save more than they spend on the very first pass.
How It Works
You book a flight. We fly your fields, run AI analysis, and hand you a prescription map your sprayer loads directly. Most jobs done start to finish in under 48 hours.

Experience & Credentials
I founded Citadel Drones because most "precision ag" tools feel anything but precise when you actually put them to work in the field. Too often, they overpromise, underdeliver, complicate workflows, or waste time with unreliable outputs.
My background includes hands on work with drones and field data, rigorous quality control and assurance processes, and inspecting civil engineering projects for FHWA, KDOT, and various city/county jobs. I have also worked in Research and Development at a specialized leader in advanced composites that has been quietly powering cutting edge aerospace programs for decades. This aerospace environment instilled a deep appreciation for precision engineering, repeatable processes, reliable data, and systems that perform under demanding conditions. Principles I now apply directly to agricultural drone services.
That is why Citadel Drones keeps things straightforward: we fly your field with RGB and multispectral technology to collect high quality imagery, process and analyze the data using proven AI pipelines, generate clear weed maps and actionable prescription maps, and deliver them ready to load directly into your sprayer controller. No fluff, no unnecessary steps just the clear view you need to target weeds effectively, cut herbicide use, and protect your bottom line.
Every part of our process draws from techniques I have personally researched, tested, and refined, backed by public university studies and real-world field trial data from Kansas and beyond. When you work with Citadel Drones, you are getting services built by someone who brings aerospace-level attention to detail and technical rigor to Kansas farming.
Proven by Research
40–76%
Near 50% herbicide product savings and $13.42 per acre in reduced chemical costs on soybeans. 94% weed detection accuracy confirmed in field trials.

Iowa State University
Drone Weed Mapping Study, 2024
Average herbicide savings of 59% across over 1 million acres of corn, soybean, and cotton. A Kansas farmer near Salina cut his herbicide costs by two-thirds using this technology.

John Deere See and Spray
Industry Data, 2024-2025
Herbicide savings from 44% to 91% across five soybean fields totaling 415 acres. Average product savings of 76% and economic savings of $15.70 per acre.
