About Gerbco
Gerbco Disc Sealers corn logo EPS.png

The NH3 Disc Sealers, manufactured by Gerbco Inc., were designed by Indiana farmer Keith Gerber in 2004.

Gerber, a grain farmer for the past forty years, had experienced too many years of nitration loss when pre-planting his anhydrous ammonia. This caused him to switch to side-dressing NH3.

I am very satisfied with the Disc Sealers. They do a wonderful job preventing us from covering up small corn.

I’m very satisfied with the disc sealers. They do a great job sealing. I have a 17 knife applicator and I need a good disc sealer that’s also trouble free. I also like the idea of using my used planter seed discs for the sealer blade. If a bearing goes out I just put another on. That was a brilliant idea!

I like being able to drive at good speed when corn is small and not worry about covering it. I also like using my seed discs that I would normally throw away.
