Two sets of [[enzymatic reaction]]s are highly relevant to the efficiency of nitrogen-based fertilizers. <br />
;Urease<br />
The first is the [[hydrolysis]] (reaction with water) of [[urea]] ({{chem2|CO(NH2)2}}). Many [[soil]] [[bacteria]] possess the enzyme [[urease]], which [[catalysis|catalyzes]] the conversion of urea to [[ammonium]] ion ({{chem2|NH4+}}) and [[bicarbonate]] [[ion]] ({{chem2|HCO3-}}).<br />
;Ammonia oxidation<br />
[[Ammonia-oxidizing bacteria]] (AOB), such as species of ''[[Nitrosomonas]]'', [[Redox|oxidize]] ammonia ({{chem2|NH3}}) to [[nitrite]] ({{chem2|NO2-}}), a process termed [[nitrification]]. [[Nitrite-oxidizing bacteria]], especially ''[[Nitrobacter]]'', oxidize [[nitrite]] ({{chem2|NO2-}}) to [[nitrate]] ({{chem2|NO3-}}), which is extremely [[solubility|soluble]] and mobile and is a major cause of [[eutrophication]] and [[algal bloom]].</div>FuzzyBot
