| In another post I asked about the nitrogen fixing on bean roots because I heard that Australian soil doesn't have the right properties for this to occur.
Raymondo very kindly replied " It's a bacterium that's missing, one of the rhizobium group, often unique to each leguminous plant. If you want them there you usually need to innoculate the seed before sowing. Green Harvest in Q'ld offers the innoculant with each packet, but it's optional. When you pull out the beans, roots and all, and if there are whitish nodules on the roots then the bacteria were present. I usually just pull out a few and if present, just cut the rest off at the base leaving the roots in the soil."
I've pulled up a couple of beans and found little balls on the roots. Very exciting ! I've chucked a picture up and would appreciate knowing if these are the things I'm looking for!
