Yes, grasses (Echinochloa crus-galli, Setaria sp.) are very healthy, and so does quack grass in some spots. I find them the most in lower areas at the fields heads, where machinery turns and compaction is more severe, increasing at the same time the swinging between wet and dry conditions .The use of power harrow seems to help them. I am trying to reduce tillage but I have not yet found a viable way for organic no-till, so some tillage is at the moment unavoidable for me.
