All soil is made, whether by Nature or with a little help from us.
No, I don't think so. Why not cover up the soggy little balls with more
straw, clippings, compost, or whatever you have on hand so that the ash is gradually incorporated and absorbed into the soil, where the microbes, soil life, and
roots can get at the minerals. If you have a lot of soil life and microbes, they'll do the pH balancing for you to about neutral.
