Hi all having now burnt my prunings from black currants and raspberries where would others consider the best crops to benefit from the ash??

Around your fruit bushes would be good, potash is good for fruit production

Sure I've read it here somewhere - the most potash is in younger growth.  If so do old logs contribute owt?
Any comments welcome : plot partner burns logs

Later in season on fruit and flowers or anything you want to ripen etc 😀👍

Well, any wood ash is going to be from mature wood. Potassium is quite mobile in plants, so as long as there is fluid moving up or down in the wood tissue, potassium is likely to be in the wood regardless of age.  There may be some variation over the life of a tree, of course.  As to how much mineral matter is in the ash, your friend Wikipedia has some general information:  https://en.wikipedia.org/wiki/Wood_ash 

Wood ash contains quite a bit of calcium, therefore you can use it in place of ground limestone for it's liming potential.

we only burn wood on our wood burner so we have quite a lot of ash left over we tend to use we spread the ash on the ground prior to planting but mainly on our onion beds

Whatever type of woody material was burned to make the ash, it will raise the pH of any soil it's added to - good if your soil is too acidic, but avoid using on ericaceous crops like blueberries.
