Further subprograms are currently under development, including for the promotion of nitrification inhibitors used in combination with organic fertilizers (manure).
(2006) Scope and Strategies for Regulation of Nitrification in Agricultural Systems — Challenges and Opportunities.
«We now have a better understanding of the environmental abundance of ammonia - oxidizing microorganisms and the process of nitrification.
It could never be found until recently, in a fish tank a few floors below Radboud University's microbiology department: one single organism able to perform the complete process of nitrification.
Not exact matches
It consists of a primary clarifier, a UASB type of anaerobic reactor (ANUBIX ™ - B), a pre - and post denitrification, a nitrification and post aeration, a clarifier and a final DAF for phosphorous removal with iron chloride.
When the mixture is added to soil, it boosts the population of micro-organisms responsible for nitrification, which is essential for plant nutrition.
Dr Pinto says: «The discovery of a single microorganism capable of full nitrification will have a significant impact on our understanding of the nitrogen cycle and on efforts to manage nitrogen pollution.

Global declines in oceanic nitrification rates as a consequence of ocean acidification.
Ocean acidification is also predicted to reduce microbial production of nitrate from ammonium (Beman et al., 2011), which could have major consequences for oceanic primary production because a significant fraction of the nitrate used by phytoplankton is generated by nitrification at the ocean surface (Yool et al., 2007).
Nitrification, the oxidation of ammonia via nitrite to nitrate, has always been considered to be a two - step process catalysed by chemolithoautotrophic microorganisms oxidising either ammonia or nitrite.
Nitrification is a special problem in Long Island Sound and the Chesapeake Bay, which have absorbed large amounts of nitrogen from coal - burning power plants in the Midwest.

Nitrous oxide, a potent greenhouse gas also known as N2O, is released as a byproduct of the bacterial conversion of nitrogen in agricultural soils, the so - called nitrification and denitrification processes.
