Agro-ecosystems have developed from mixed- and multiple-cropping systems with relatively closed N cycles to intensively managed monocultures with large N inputs in the form of commercial fertilizers. Cultivation of increasingly larger areas of land has r

(DNA and RNA) and in the energy transfer molecule adenosine triphosphate. The human body contains about 3% nitrogen by mass, the fourth most abundant element in the body after oxygen, carbon, and hydrogen. The nitrogen cycle describes the movement of the element from the air, into the ...
NITROGEN cycleThe marine nitrogen (N) cycle profoundly impacts global ocean productivity. Amid rising deoxygenation in marine environments due to anthropogenic pressures, understanding the impact of this on the marine N-cycle is vital. The Black Sea's evolution from an oxygenated lacustrin...

(III)HBED has a stability constant of 39, as compared to iron citrate (Fe2+) that has a significantly lower stability constant of only 3.2. For reference, stability constants for selected metal chelates is shown in the chart below. See Arthur E. Martell & Robert M. Smith, Critical ...
Nitrogen, phosphorus and carbon originating from wastewater and sludge can, depending on their partitioning during wastewater treatment, either become available as potential resources or leave as emissions. Several reviews have highlighted the dependence of life cycle assessment (LCA) results on the invent...
(such as agriculture, industry and urban activities) in aquaculture ecosystem, there is a pressing need to understand the basic mechanisms that underlie microbial N transformations26. The biochemical N cycle pathways that are dominated or catalysed by microorganisms are waiting to be discovered. Third...
