Pretty high in P and low in K compared to quite a few dry plant products,

difficult to shift pH very far from the native soil pH on a long term
basis, but repeated applications can do it.  How about a little lime?

I remember running across a recent publication that appeared to be saying
that new research is showing that oak leaves, pine needles, etc. are not
effective in shifting soil pH. I was surprised! Do you have any information
on this?
