Green manure

I'm not really able to get hold of muck in any real quantity, so was thinking green manure next winter might help things a bit.
What set me off was I was passing a wheat field recently and in one area there was what looked like broad beans growing amongst the crop.
The wheat in that area was at least as half as high, again, as the rest of the field.
I'm, guessing it was the beans providing extra nitrogen.

This was a couple of months ago, so, I bought some broad bean seeds and planted them fairly close to my outdoor toms, I've just harvested a reasonable crop of beans, but its difficult to say if they have been any help to the toms, which are growing well.

I'm now thinking on what I can plant this autumn, to dig in next spring.
Any ideas would be welcome.

 

I use Phacelia and Trefoil as green manure both can be planted now to dig in the spring
I do let the Phacelia flower for the bees as they love it
The Trefoil can be planted under things

 

I'm mostly looking for something to sow after my maincrop spuds, say mid Sept.

 

@pete
I use Italian rye grass, red clover and mustard for September/October sowing. I've also used field beans and vetch at that time of year.

 

My pal on the next plot to me swears by mustard ,has 2 lots sown already ,with one crop about ready for digging in.Since he started with it some years ago he has had very littel problems with keal slugs and wire worm in his potato crops.

 

Mustard is good as it has big leaves (which you can eat if you don't mind eating hairy things )

Stops the rains washing the nutrient out

 

OK, good advice any thoughts on where to buy?

 

Most Garden centres do bulk packs, i'd add alfalfa to the list too, unless someones already mentioned it

 

There is a variety called Caliente Mustard that is supposed to act as a biofumigant. If chopped finely and dug in it suppresses soil pests.

 

Most of the seed companies sell green manures.

I've found them expensive in most places, Moles seem to be the best (although they charge carriage for Pea & Bean seed, and green manures, so best to buy them all on the same order!!

Mustard is a brassica, so worth considering within your crop rotation (esp. if you have Clubroot)

I'm going to steer clear of mustard, the allotments have a history of club root.

For no real reason I think I might try Phacelia or vetch, or maybe both, on different parts.
