Ammonification will release N[H.sub.4.sup.+]-N which will then be nitrified to N[O.sub.3.sup.-]-N as long as nitrifying bacteria are present.
Biochemical processes associated with soil pH change are mainly as follows: the release of alkalinity, ammonification of organic nitrogen, nitrification of mineralized nitrogen, and cation-exchange reactions between cations and exchangeable acidity (MOKOLOBATE & HAYNES, 2002; WANG et al., 2009; ZHAO & XING, 2009).
While the reactions taking place in total nitrogen abatement take place more effectively in pH ranging from 6.5 to 8.5 [26], such as ammonification reactions require a pH in between 6.5 to 8.5.
The selection method, which was used to select the microorganism from biofertilizers for ammonia determination consisted of ammonification, nitrate reduction, and nitrogen-fixation.
The positive result of wheat dry matter yield with CS application, although its total N and ammoniacal N contents are lower than those in the PS (Table 2), may occur because approximately 80% of CS is composed by amino acids that are easily mineralizable and undergo fast hydrolysis and ammonification, thus being more easily assimilated by plants (Zaman & Blennerhassett, 2010).
Microbial immobilization of ammonium and nitrate in relation to ammonification and nitrification rates in organic and conventional cropping systems.
During the composting process the total nitrogen contained in the organic matter goes through ammonification (N[H.sub.2] and N[H.sub.3]), and then undergoes the nitrification process to nitrite (N[O.sup.-2]) and nitrate (N[O.sup.-3]) (Bech-Friis, Smars, Jonsson, & Kirchmann, 2001, Kiehl, 2004, Kumar et al., 2010).

This is due to a decrease in the process of ammonification in nitrogen-poor environments.
As the temperature increases, soil ammonification and nitrogen mineralization also get increases.
pseudotuberculosis biovar Equi also shows the pathway of ammonification in dissimilatory nitrate reduction to ammonium, what has been proposed as catalyzed by the enzyme nitrate reductase Nar and nitrite reductase complex NrfAH, a membrane-associated cytochrome; see Figure 3.
