can anybody tell me how much wood ash i can put on my allotment and compost heap,Please

not sure abot environment issues but a chap at our lottie is constantly searching out wood & cardboard for bonfires for the ash & I must say he prob has the best crops on site!!the little ash we've had from our few fires has defo helped to break up claggy soil.not sure how much is too much or if indeed you can have too much but we try to have as few fires as poss due to environment issues.

Cardboard doesn't produce the "right" kind of ash.
Wood, however, is perfect (so lond as it is untreated). If you are concerned about the "environmental" aspect - don't be. Burning wood produces some 10x LESS carbon than leaving it to rot.

I don't see how rotting wood can possibly create more CO2 than burning it.The carbon is part of the wood, and will be released one way or the other, unless you make charcoal, in which case you aren't getting the available energy anyway.
If you are getting useful heat from your fire, that you would otherwise get elsewhere, you are certainly doing good overall, because it WILL rot eventually, so best to use the energy released (along with the CO2).
Woodash is alkaline, and you can make soap by combining it with vegetable oils or animal fat (but I haven't yet managed to get it to work properly, must keep trying).
