The trial above was conducted by Royal Barenbrug Group. It is the largest privately owned grass seed company in the world and develops products for the turf industry including golf fairways and greens, sports turf, and professional landscapes and residential lawns.
They compared seeds treated with SumaGrow against a control on Bent Grass. The seeds were coated prior to planting (SumaGrow treated trays on the left and control trays on the right). Their initial reaction when the grass began sprouting is that the SumaGrow treated seeds had "a better/faster emergence compared with the standard."
