Some Observations on “Nitrification” [PDF]
It is now a well-established fact that the ammonia, which is formed in the cultivated soil by the breaking down of nitrogenous organic matter through the action of bacteria and moulds, is itself converted by oxidation into nitrates. The latter process, “nitrification“ proper, is effected in two stages by two distinct species of bacteria, the one ...

Tertiary nitrification of wastewater in trickling filters [PDF]
This study was designed to investigate, at laboratory and pilot scale, the effects of various loading and climatic factors on the nitrification perfon-nance of four media, and to undertake a comparative assessment of the media.

Biochemistry of nitrification in soil: 2. The site of soil nitrification. [PDF]
Chick, in her interesting paper (1906) on the study of nitrification with reference to sewage purification, states that it had been long upheld that a most important preliminary to nitrification both in soil and in sewage filters was an absorption of NH+4 or ammonium salts on surfaces of soil particles, or filtering medium.

A study of nitrification in lakes of the English Lake District [PDF]
This thesis was submitted for the degree of Doctor of Philosophy and was awarded by Brunel University.Nitrification became the dominant nitrogen transformation in a number of lakes which accumulated ammonium, in hypolimnetic water, under aerobic ...

N-Tox® - Early warning of nitrification toxicity for activated sludge treatment [PDF]
N-Tox® is a new technique for evaluating the nitrification efficiency in industrial or municipal activated sludge systems, using direct measurement of nitrous oxide (N20) as an indicator of nitrification failure.

In silico evaluation of plant nitrification suppression effects on agroecosystem nitrogen loss
Nitrification regulates the potential for nitrogen (N) loss from ecosystems because it converts ammonium to nitrate, which is susceptible to leaching and gaseous emissions.

Effects of elevated atmospheric carbon dioxide concentration on nitrification of farmland soil
It has been widely reported that elevated carbon dioxide concentration (eCO2) affects soil nitrogen cycling dramatically, in which nitrification plays an important role in net primary productivity and greenhouse gas emission.

Application of litters to inhibit nitrification in Vertisols on sweet corn (Zea mays S.)
Nitrification, or the process of oxidation of ammonium to nitrate in the soil, needs to be inhibited because it reduces the efficiency of nitrogen fertilizers.

Rhizosphere soil nitrification ability controls nitrogen‐use efficiency in rice growth period
Nitrification in the rhizosphere is a crucial process in controlling nitrogen‐use efficiency (NUE) in flooded paddy soils. To understand the relationship between the nitrification ability of the rhizosphere and NUE, pot experiments using 15N tracer ...
