I am following up on some interesting earlier posts in February and March about rewoquat and its US equivalent. I used Quaternary-O as a lab technician many years ago and now have a variety of samples on which I’d like to use something similar. Matthew, how did the sample of Rewoquat work out? You said that you received a sample of Rewoquat “W 3690 PG” — is that the variety (I see there are 9 varieties at the Evonik website) that you or Evonik thought would be the most appropriate for breaking up clay-rich rocks? Is it your sense there might be a way for folks to order small to modest amounts in the US?

Thanks much,

Rob Ross
