I follow Mark, he is using many of the same seeds as what is mentioned above. he makes his own mix from those seeds. More power to him. As also said above, he is running most of that on a high fence operation with an unlimited budget. Again, more power to him.
Mark just wants you to pay him so he can tell you what many of us already know. And yes, I'm sure he knows plenty more, just ask him.

Just an fyi, he is using awnless wheat as his wheat seed he drills into the clover. He is using Barduro Red Clover on those beautiful pink flower clover plots and either 805 or 505 bulldog alfalfa. On his beans I can promise you he isn't using just some random soybean from the coop.
he is also using sun hemp and a climbing cowpea and/or lablab in the other summer plots.
His secret is having the time and $ to manage those crops as they should be.

Maybe this won't turn into another Mark thread smh
