BSK the turkeys on my place would have eaten the buckwheat by now.
Oh they certainly did take their toll (and still are), but from all of the mowing of weeds and grasses we've done in our plots over the years (without ever turning it into the soil) we've got a pretty thick thatch of dead grasses on the ground. This certainly doesn't help germination but it does help hold moisture in the soil and it protects quite a bit of the seed from turkeys.
