Plants can't use ammonium but bacteria
will

convert it to nitrate, the form of nitrogen plants can use but the
plants

won't get it until the bacteria release it.

Actually, that is incorrect. Plants can take up both the nitrate and
ammonium forms of nitrogen. They cannot, however, take up the nitrite form
of nitrogen. Some plants, such as blueberries (and I believe some other
members of the ericaceae) can ONLY use nitrogen taken up as urea or in the
ammonium form and not the nitrate form. Thus Calcium Nitrate may be a great
fertilizer for your strawberries but will not help your blueberries at all.
Blueberries need nitrogen provided in the form of ammonium or urea and it's
uptake by the plant is independant of any bacterial action converting the
nitrogen to nitrate.
