It isn't the same bacteria. Sweet pea belongs to the Vetch grouping.
A different bacteria on clover then on vetch group. For clover there is the Red Clover group and the Alfalfa group. They have different bacteria, and differernt then vetch group.

Great idea. Currently I grow clover (a weed). I can check its roots. Though, I don't know if the same bacteria that fixates Nitrogen grow on both 
sweet peas and clover.  I am thinking about not  pulling the clover any
more and letting it stay and fixate N. My soil is poor in organic matter and 
sandy.

Sweet  pea falls into "Vetch group" containing  field pea, garden pea,
broad-been and various vetches. Without testing you can't tell if the 
right bacteria is there or not. chances are high that it is,  but
perhaps not in high enough concentration. Concentration increase with
succeeding years of growing one of that group.

You can test  yourself. Plant some sweet pea. Did up a plant after it
has grown for  awhile. The presence or absence of nodules will be
obvious, as well as  number of nodules. See following article for more
information.

Subject: [iris] Brocolie as a green manure crop control  soil diseases

The extension agent  recommended to me to consider  the use of broccoli
grown up to just before flowering and then incorporating them into the 
soil.
Broccoli can help suppress   disease in soils when you want to renew an
iris
bed. He said to do a Google search on Rotation with Broccoli for soil 
borne
Disease.   Has  anyone experience with broccoli to  eliminate soil
diseases?

The broccoli discussion came about   because I was discussing using
sweet
peas (dwarf) in between irises to fixate Nitrogen in to the soil. He 
said
that  planting Sweet Peas  will not increase soil nitrogen if they do
not  have
the right soil rhizobium  inoculant, nor if the soil already has
sufficient
nitrogen.  Plus he  said you would have to work it  in before flowering.
Has anyone  grown sweet peas  in between the  irises in the spring and
winter?  Do they crowd the   irises?  I am doing an article on green
manure for
the club newsletter and website. Can anyone send me pictures of sweet 
peas
grown amongst the  irises?  I have known that the  inoculant you can buy
varies with cover  crop.  I would like to  buy some inoculant to help
the sweet
peas fix  nitrogen in to the  soil but am not sure which one.   Any
recommendations?

Thanks
Scarlett
