Nitrification-denitrification in WSP: a mechanism for permanent nitrogen removal in maturation ponds [PDF]
, 2009 A pilot-scale primary maturation pond was spiked with 15N-labelled ammonia (15NH4Cl) and 15N labelled nitrite (Na15NO2), in order to improve current understanding of the dynamics of inorganic nitrogen transformations and removal in WSP systems.

The effect of precipitation and application rate on dicyandiamide persistence and efficiency in two Irish grassland soils [PDF]
, 2015 peer-reviewedThe nitrification inhibitor dicyandiamide (DCD) has had variable success in reducing nitrate (NO3-) leaching and nitrous oxide (N2O) emissions from soils receiving nitrogen (N) fertilisers. Factors such as soil type, temperature and moisture

MODELING OF THE NITRIFICATION PROCESS IN A SOIL IN CĂLĂRAŞI COUNTY [PDF]
Scientific Papers Series : Management, Economic Engineering in Agriculture and Rural Development, 2015 Quantifying the best possible the nitrification of nitrogen in the soil remains an important issue for the sustainable agriculture and for the environmental protection. The aim of the study was to evaluate in the laboratory the influence of some factors:

Dicyandiamide as nitrification inhibitor of pig slurry ammonium nitrogen in soil
Ciência Rural, 2016 : Inhibition of nitrification of ammoniacal nitrogen pig slurry after its application to the soil can mitigate nitrogen (N) losses by nitrate (NO3 -) denitrification and leaching, with economical and environmental benefits.

Effects of Phosphorus on Nitrification Process in a Fertile Soil Amended with Urea
Agriculture, 2021 While the effects of carbon on soil nitrogen (N) cycle have been extensively studied, it is not clearly understood how co-existing macronutrients, such as phosphorus (P), affect the N cycle in agroecosystems.

A mathematical model of bacteria capable of complete oxidation of ammonium predicts improved nitrogen removal and reduced production of nitrous oxide [PDF]
, 2017 The removal of excess nutrients from water ecosystems requires oxidation of toxic ammonium by two types of bacteria; one oxidizes ammonium to nitrite and the other oxidizes nitrite to nitrate.

Short‐term impact of fire on the total soil microbial and nitrifier communities in a wet savanna
Ecology and Evolution, 2021 Savannas are characterized by the coexistence of grasses and trees. Fires are critical for their coexistence, because they decrease the survival of tree seedlings and saplings and their recruitment to the adult stage.
