I've always wondered about this nitrogen fixing business. (And I hadn't
realised it applied to peas as well as beans)

almost all legumes do it. If you lift a root and shake off the soil you
can see the small white blobs.


I believe there's new thinking Janet, that the nodules are not as has
always been thought, helpful to other plants. Can't remember where I
heard it, might have been a lecture or in a gardening magazine.
