A question that could save us a lot of time and money...

Does boric acid block urease actvity?

We're collecting leachate from a large scale lysimeter experiment, and have
been using boric acid in the collection vessels to prevent denitrifciation etc.
However, as urease seems to be significant as a free enzyme, we don't know
if we've been stopping Urea->NH3.

If not we'll go to using phenyl phospho di-amidate or something.

Thanks in advance, Terry Brown
