Editing Manganese deficiency (plant) (section)

== Treatment ==
Manganese deficiency is easy to cure and homeowners have several options when treating these symptoms.  The first is to adjust the soil pH.  Two materials commonly used for lowering the soil pH are [[ammonium sulfate]] and [[sulfur]]. Ammonium sulfate will change the soil pH instantly because the ammonium produces the acidity as soon as it dissolves in the soil. Sulfur, however, requires some time for the conversion to [[sulfuric acid]] by soil bacteria.  If the soil pH is not a problem and there is no manganese in the soil then [[Foliar feeding]] for small plants and Medicaps for large trees are both common ways for homeowners to get manganese into the plant.<ref>Messenger, A. Steven. ''Response of interveinally chlorotic red maple trees treated with medicaps or by soil acidification''. J. Environ, 1990, p. 2.</ref>

To mitigate issues with manganese deficiency, [[Manganese(II) oxide|Manganese oxide]] and [[Manganese sulfate|sulfate]] are components of fertilizers.  In the year 2000, an estimated 20,000 tons of these compounds were used in fertilizers in the US alone.<ref>{{cite book |doi=10.1002/14356007.a16_123 |chapter=Manganese Compounds |title=Ullmann's Encyclopedia of Industrial Chemistry |date=2000 |last1=Reidies |first1=Arno H. |isbn=9783527303854 }}</ref>
