SF-50 Seeding & Fertilizer UAV

50 L Hopper Precision Broadcasting for Seeds & Fertilizer

The SF-50 Seeding & Fertilizer UAV combines seeding, broadcasting and variable-rate fertiliser application in one efficient platform. A 50-litre hopper with an adjustable spreader delivers uniform coverage across up to a 20-metre swath, and can plant rice, wheat, grass and cover-crop seeds with calibrated drop rates. Centimetre-level RTK guidance and automated boundary mapping let operators broadcast precisely along field edges and around obstacles without overlap or waste. Variable-rate control adjusts output on the fly according to a prescription map, cutting input costs while improving establishment. The self-cleaning hopper and washdown airframe make turnaround between fields fast. Mission data is logged to the cloud for accurate agronomy records and repeatable application.
