Therefore, the increased soil microbial biomass in the rhizosphere of E+ grasses that is indexed by the arginine ammonification (Table 1) can be considered as an indirect mechanism to explain the increased activity of alkaline phosphomonoesterase in the rhizosphere of endophyte infected plants.
Ammonification is the conversion of nitrogen in organic compounds to ammonia.

Benthic sediments and the hyporheic zone are known to be active sites of N transformations, including nitrification, denitrification, and ammonification (Jones et al.

Overall biological activity can be measured by the amount of carbon dioxide emitted and, more analytically, by drawing up an inventory and count of 1) the mesofauna (nematodes, annelid worms, microarthropods, arachnids, apterygote and pterygote insects, myriapods, isopod and decapod crustaceans, rotifers, tardigrades, molluscs), 2) the microbiota (protoctists and the microorganisms that perform the essential processes of denitrification, ammonification, and nitrification; the other bacteria; and microsymbionts like Rhizobium, Klebsiella, Spirillum, or Azospirillum), and 3) the mycota (fungi and lichens).
Rates of ammonification, nitrification, denitrification, and oxygen consumption were calculated from differences in final and initial concentrations in the overlying water in the sealed cups after 0, 18, 40, 48, 72, and 161 h.
Net ammonification and nitrification were calculated as the net changes in the N[H.
net ammonification plus net nitrification rates) are substantially less than the total N uptake by E.
The ammonification process produces hydroxyl ions and ammonium ions, and when the soil pH is elevated, this results in ammonia volatilisation and loss to the atmosphere.
