between roots and brassicas

[Mantha81]

Hi, I'm wondering someone can help. Last year I planted carrots in a particular area and obviously all gone now! I've read that after roots come brassicas but most aren't planted until mid to late summer. What can I plant in this area as a potential stop gap as I hate seeing it empty?

Thanks in advanced of your help, Mantha

Maybe some salad crops like lettuce, radishes and spinach would be good?

my brassicas follow my beans,peas etc

my brassicas follow the legumes too (for the nitrogen that is supposedly left in the soil)

Me too, been doing it for years and years ...

... but I recently read that the residual Nitrogen is a myth. Not to say that the rotation isn't sensible for other reasons though ...

You're going to ask me to find the article I read now, aren't you?

Yes. (I think it was posted a few weeks ago)

Nitrogen Fixing Bacteria - Rhizobia

Radish is the fastest growing veg I can think of. There's some great varieties out there, in all sorts of different colours.

Don't know if some broad bean plants would be gone by the time you put your brassicas in?

My brassicas follow my legumes too with the carrots etc following on from the brassicas. I tend to grow lettuce, radish and spring onions in the brassicas beds until the cabbages etc take up all the space but most of my brassicas are in by late June and some earlier than that.

I recently read that the residual Nitrogen is a myth.

I was erring on the myth side too, because when I have pulled up the roots I've not seen any nodules to speak of. Wouldn't the bean/pea plant just use it all up for itself? Not leaving any in the ground ?

Sorry, haven't found it. I had a notion that it was in the Garden magazine (the one that comes with RHS membership).

From memory the article said as you have T.S. that the symbiotic association for Legumes is just that, and after the plant dies the Nitrogen fixing bacteria perish too. So there isn't a residue of Nitrogen, per se.
