Does anyone have experience or advice on Hoody Winter Barley from Geertson Seeds?  I'm thinking of seeding some here in the next few days, perhaps with orchard mixed in. 

It's currently in a very poor stand of orchard grass, thinking of spraying Roundup to kill the cheatgrass, spreading manure, disking, broadcast fert and seed, then rollerharrow.

 
Or maybe just no-till then roundup.

Any advice?
