The title of this article is incorrect. The correct title is, "The Effect of Different Ammoniacal Sources on Soil Acidification.

Also, equation 4 on page 547 is incorrect. The correct equation 4 is as shown:

RLR = [(VAS - Vcheck)/ (VAN or urea - Vcheck)]

Also, on page 649 tables 5 and 6 had "RLR, %" as the main heading under the title. The correct heading is "RLR†".
