We run commercial ground rigs and precision agricultural drones across dryland wheat acreage in Walla Walla and Columbia counties.
Three D Farms delivers targeted chemical and nutritional applications built specifically for the steep slopes, rolling benches, and variable weather windows of eastern Washington wheat country. Whether treating heavy broadleaf weed flushes across wide benches or applying late-season flag-leaf fungicide into steep draws without leaving wheel tracks, our equipment is staged, calibrated, and operated to protect your crop yield.
Our high-clearance ground sprayer treats large dryland wheat benches with wide-swath boom efficiency and automated drift management.
For open rolling wheat fields where ground travel is safe and efficient, our commercial high-clearance wheel sprayer provides massive daily capacity. With a ninety-foot boom span, pulse-width modulation nozzle control, and real-time GPS auto-guidance, our ground rig applies uniform carrier volumes across varied terrain elevations. We maintain accurate target pressure regardless of tractor speed fluctuations along contour ridges.
Ground application is particularly suited for early spring broadleaf weed passes, fall pre-plant or post-harvest burn-downs, and early jointing stage canopy nutrition. Rates for ground field treatment range from $14.00 to $28.00 per acre depending on field acreage density, chemical formulation, carrier volume requirements (ranging from 8 to 20 gallons per acre), and haul distance from our Reservoir Road depot.
| Operational Specification | Ground Rig Parameter | Agronomic Benefit to Grower |
|---|---|---|
| Application Rate Range | $14.00 – $28.00 per acre | Transparent pricing based on field acreage, volume, and chemical mix. |
| Working Swath Width | 90-foot commercial boom | Broad swath minimizes wheel passes and finishes large blocks quickly. |
| Nozzle & Pressure Control | Pulse-width modulation with auto-shutoff | Consistent droplet spectrum with zero overlap at field turnarounds. |
| Shift Daily Capacity | Up to 600–800 acres per shift | Knocks out entire field runs before impending spring rain systems. |
| Minimum Dispatch Unit | 1 complete field (shift reservation) | No multi-thousand-acre contract required to book our ground equipment. |
Our precision agricultural drone treats steep hillside coulees and late-stage flag leaves without compacting soil or crushing standing wheat.
When winter wheat approaches flag-leaf emergence or early flowering, driving a twelve-ton wheeled sprayer across the field knocks down standing stems and leaves permanent wheel tracks that directly reduce final harvest bushels. On steep Palouse and Walla Walla hillside draws, ground machinery also faces severe slip, ditch rutting, and equipment rollover risks.
Our unmanned multi-rotor agricultural spray drones fly eight to twelve feet directly above the wheat canopy, dispersing an exact twelve-to-sixteen-foot spray ribbon driven downward by propeller downwash. This vortex drives fungicides and foliar nutrients deep into lower canopy leaves where stripe rust spores incubate. Drone application rates stay between $12.00 and $16.00 per acre, providing a cost-effective aerial solution with zero wheel trample and single-field shift flexibility.
| Operational Specification | Precision Drone Parameter | Agronomic Benefit to Grower |
|---|---|---|
| Application Rate Range | $12.00 – $16.00 per acre | Direct per-acre economics with no aircraft ferry fees or runway requirements. |
| Canopy Yield Trample | 0.0% ground contact | Saves the 2% to 4% bushel loss caused by heavy sprayer tires in mature stands. |
| Flight Swath & Altitude | 12–16 ft swath, 8–12 ft AGL | Propeller downwash pushes active ingredient deep into dense crop foliage. |
| Terrain Capability | Steep coulees, terraces, saturated draws | Applies crop protection in areas impossible or unsafe for wheeled tractors. |
| Flight Guidance | Centimeter-accurate RTK positioning | Follows hillside contours and locks to boundary edges without overspray. |
We schedule field shifts around critical agronomic application windows so treatments stop rust before fungus damages kernel fill.
Dryland wheat yield in Walla Walla and Columbia counties is won or lost during narrow operational timing windows. Missing an active stripe rust cycle by forty-eight hours or delaying herbicide until downy brome hardens off severely penalizes bushel output. We maintain close communication with our growers to stage equipment precisely when field conditions and crop stages align.
Broadleaf Herbicide & Tillering Boost
Ground rig or drone passes addressing winter annual broadleaf weeds, kochia, and Russian thistle before they rob early spring soil moisture from tillering winter wheat stands.
Stripe Rust Protection (Jointing Stage)
Early fungicide application targeting stripe rust sporulation on lower leaf surfaces as daytime temperatures warm, preventing spore transfer to emerging upper leaves.
Flag-Leaf Fungicide & Foliar Nutrition
Precision drone spraying applying protective fungicides and micronutrients directly over the crucial flag leaf without leaving tire ruts or breaking standing heads.
Pre-Harvest Dry-Down & Fallow Burn-Down
Uniform desiccant application or post-harvest stubble chemical weed control to conserve deep subsoil moisture reserves across summer fallow rotations.
Our nurse tender truck batches clean water and agricultural chemicals on-site to preserve mixture integrity and prevent line settling.
Chemical efficacy depends heavily on carrier water quality, water pH, and proper mixing sequence. Allowing concentrated crop protection products to sit stagnant in an applicator tank over long transport hauls can cause chemical fallout, uneven dilution, or nozzle clogs.
Three D Farms stages dedicated nurse tender units directly at your field approach along county access roads. Our trucks carry clean poly storage tanks, high-flow transfer pumps, and calibrated venturi induction hoppers. We batch immediately before each load enters the applicator, whether filling our ninety-foot ground boom sprayer or hot-loading precision aerial spray drones. If you supply packaged chemical totes at the field, our operator verifies compatibility and measures induction rates according to strict label parameters.
Choose application labor only using your farm chemical account, or full-service procurement managed by Three D Farms.
Clean water transported in poly tanks with filtration to protect precision nozzles and maintain uniform chemical suspension.
We monitor anemometer wind speeds and enforce label buffer distances to prevent chemical movement off-target.
