Gerbco’s 28% Disc Sealers are designed to seal the knife trench to avoid nitrogen volatilization and also to prevent erosion which can develop with open trenches.
We also recommend purchasing the sealers without blades and you use your own worn planter seed discs to reduce your purchase price.
The heavy duty, powder coated sealers are very low maintenance and economical.
