Nitrogen transformations in aquaponic systems: A review
TLDR
This review critically examines the important fates of nitrogen from input to outputs (e.g., ammonia nitrogen generation, nitrification, nitrate assimilation and nitrogen loss) to improve NUE in aquaponic systems to advance current understanding of nitrogen transformations.About:

Aquaponic trends and challenges – A review
Brandon Yep,Youbin Zheng +1 more
TL;DR: A review of aquaponics literature can be found in this paper, where the authors analyzed over 529 publications published from 1978 to 2018 and found that aquaponic technologies are becoming increasingly popular in commercial and research applications, and that a deep water culture hydroponic component and media bed component are optimal for commercial applications, respectively.
Nitrifier denitrification can be a source of N2O from soil: a revised approach to the dual isotope labelling method
D.M. Kool,N. Wrage,Sophie Zechmeister-Boltenstern,Michael Pfeffer,Dick J. Brus,Oene Oenema,J.W. van Groenigen +6 more
TL;DR: In this article, a new isotopic approach was proposed to identify the presence of Nitrifier denitrification in soil, and it was found that in at least five of the soils, Nitrifiers must have contributed to N2O production, and may even have been responsible for all NH4+-derived N 2O in most soils.

Hydroponic technology as decentralised system for domestic wastewater treatment and vegetable production in urban agriculture: A review.
TL;DR: The efficiency of a hydroponic system with regard to municipal wastewater reuse is mainly linked to its capacity to allow continuous use of wastewater through the production of agricultural crops and the removal of pollutants/nutrients, resulting to increased food security and environmental protection.
Journal ArticleDOI
Application of water hyacinth (Eichhornia crassipes) for phytoremediation of ammoniacal nitrogen: A review
TL;DR: In this article, the technical advantages and limitations of phytoremediation as compared to other nitrogen removal technologies, as well as the insight for the development of PhYM technology using water hyacinth to treat wastewater with high ammoniacal nitrogen (AN) content.

Plant and fish production performance, nutrient mass balances, energy and water use of the PAFF Box, a small-scale aquaponic system
Boris Delaide,Guillaume Delhaye,Michael Dermience,James Gott,Hélène Soyeurt,M. Haïssam Jijakli +5 more
TL;DR: In this paper, a small-scale aquaponic system named PAFF Box (Plant And Fish Farming Box) consisting of a ship container topped by a greenhouse was studied, where plant yield in ebb-and-flow and deep water culture (DWC) hydroponic beds, lettuce, basil and tilapia production capacity and water and energy consumption were investigated.

The state of food insecurity in the world 2011: how does international price volatility affect domestic economies and food security?
TL;DR: In this paper, the authors highlight the differential impacts that the world food crisis of 2006-2008 had on different countries, with the poorest being most affected, and present policy options to reduce volatility in a cost-effective manner and to manage it when it cannot be avoided.
Journal ArticleDOI
Role of nitrifier denitrification in the production of nitrous oxide
TL;DR: In this article, the authors present knowledge about Nitrifier denitrification is summarized in order to give an exact definition, to spread awareness of its pathway and controlling factors and to identify areas of research needed to improve global N 2 O budgets.

Ammonia oxidation kinetics determine niche separation of nitrifying Archaea and Bacteria
Willm Martens-Habbena,Paul M. Berube,Paul M. Berube,Hidetoshi Urakawa,José R. de la Torre,José R. de la Torre,David A. Stahl +6 more
TL;DR: Oligotrophic ammonia oxidation kinetics and cellular characteristics of the mesophilic crenarchaeon ‘Candidatus Nitrosopumilus maritimus’ strain SCM1 support the hypothesis that nitrification is more prevalent in the marine nitrogen cycle than accounted for in current biogeochemical models.
Journal ArticleDOI
Engineering analysis of the stoichiometry of photoautotrophic, autotrophic, and heterotrophic removal of ammonia-nitrogen in aquaculture systems
TL;DR: These three ammonia removal pathways are reviewed, a set of stoichiometric balanced relationships using half-reaction relationships are developed, and their impact on water quality is discussed.
Journal ArticleDOI
Physiological mechanisms influencing plant nitrogen isotope composition.
TL;DR: Intra-plant variation in isotope composition can be caused by multiple assimilation events, organ-specific loss of nitrogen, and resorption and reallocation of nitrogen.
