Arginine ammonification in the rhizosphere was significantly influenced by the genotypes and endophyte status (Table 1).
Ammonification or N mineralization is the biological transformation (decomposition and degradation) of organic nitrogen to the ammonium ion (N[H.
Integral to this degradation are several separate groups of bacteria that are key factors in the twin conversions known as ammonification and nitrification.
In the guts of invertebrates, and even in their excreta, ammonification is intense, humus formation takes place, and even atmospheric nitrogen is fixed.
Nitrogen transformation processes such as denitrification and ammonification occur in the suboxic profundal zones of stratified lakes.
increased microbial death (with subsequent release of N or changes in ammonification, nitrification or denitrification activity).
Ammonia can be produced by several processes such as, nitrite ammonification (32), degradation of various amino acids and decarboxylation of amino acids to produce biogenic amines as well as ammonia (26).
The transformation of organic matter in the soil begins with the ammonification process, whose intensity causes active development of bacteria, which are using mineral forms of nitrogen.

However, according to several authors, the process of composting slightly modifies the pH and particularly during the first days when one attends a very light acidification allotted to the production of organic acids, followed, in thermophilic phase, of a slight alkalisation following the ammonium release by the process of proteins ammonification [23].
Arginine ammonification a simple method to estimate microbial activity potentials in soils.
N mineralization was dominated by ammonification in both stand types, whereas nitrification was very limited in both stand types and did not differ between stand types (P = 0.
