pipeline said:You should only be growing legumes for a green manurecrop if you want to add nutrition to the medium! Legumes are able to form a symbiosis with Nitrogen-fixing Rhizobium spp. where the rhizobium live in small balls or nubs hanging off the roots of the legume....
Monocots and other non N fixing plants will only add organic matter to the soil because all the nutrients it adds come from soil around their roots..... If you are growing in a peat medium, this would have little effect on the % organic matter and may even cause a drop in pH because of all the material being degraded by soil microorganisms.
I hope you added a touch of dolomitic lime to your mix before this....

In our manure manual . . . we wrote an entire section on green manures . . . hopefully it will make a nice addition here . . .
