Precision matters when it comes to getting the most out of your inputs. Sun Ag offers professional custom application services to ensure crop protection products and nutrients are applied accurately, efficiently, and at the right time.

Our experienced team custom applies all crop protection and fertilizer products using modern equipment and proven best practices to deliver consistent coverage and reliable results. With Variable Rate Technology (VRT), we tailor application rates to field-specific needs—improving efficiency, maximizing yield potential, and reducing waste across every acre.

We also offer advanced See & Spray™ technology, which targets weeds with pinpoint accuracy to reduce chemical use while maintaining effective control. For timely in-season applications, our drone application services provide a flexible, precise solution when traditional equipment isn’t an option.

From pre-plant to late-season passes, Sun Ag’s application services combine technology, experience, and local agronomic insight to help you protect your crops, manage inputs responsibly, and get the most from your operation.
