Heres some more work of Bills if anyone is interested.

Its a nice series of articles, some of which is repeated in the yearly series I mentioned before. Matching your fertilizer to your water is a pretty smart thing. Its something I never thought about before reading those articles.
Ive got a question regarding the uptake of Nitrate Nitrogen. In one of Bills articles he states:
In contrast, uptake of nitrate nitrogen increases substrate-pH because OH- or HCO3- (bases) are secreted by plant roots in order to balance nitrate uptake.
In the article you linked two other authors state:
When nitrate (or other negative anions) is absorbed, the roots balance the negative charge by absorbing H+.
Sooo which is it? Im confused.
