| Hi everyone,
I’m looking to start a discussion on the practical and economic viability of using Drones (UAVs) for fertilization in corn
We all know that timing and placement of nutrients are the biggest drivers of corn yield. However, once the corn reaches a certain height (V10-V12 and beyond), traditional ground equipment can no longer enter the field without causing significant mechanical damage. This is exactly when the crop has its highest demand for nitrogen and micronutrients.
I am considering investing in or hiring a drone service for late-season liquid applications, but I have a few concerns regarding the ROI (Return on Investment):
Application Uniformity: How consistent is the coverage in tall corn, especially considering wind drift? Can drones match the precision of a high-clearance sprayer?
The "Downwash" Effect: Many claim the propeller turbulence helps push nutrients to the underside of the leaves. Has anyone seen a measurable yield bump from this late-season "boost" compared to standard soil-applied programs?
Concentration & Leaf Burn: Since drones operate with very low water volumes (ultra-low volume), the fertilizer mix is highly concentrated. In hot climates like ours (Adana/Turkey), is leaf scorch or "burning" a major risk?
Operational Efficiency: In heavy clay soils (Vertisols) where tractors get stuck after irrigation, drones seem like a lifesaver. But is the hectares-per-hour capacity sufficient for large-scale operations?
I’d love to hear from anyone who has integrated drones into their corn program. Does the extra yield justify the service or equipment costs, or is it better to stick to traditional fertigation or early-season soil applications?
Looking forward to your professional insights!
Best regards, | |
