The efficient catalysis of nitrogen (N 2) into high-value N-containing products plays a crucial role in the N economic cycle.However, weak N 2 adsorption and invalid N 2 activation remain two major bottlenecks in rate-determining steps, leading to low N 2 fixation performance. Herein, an effective dual active sites photocatalyst of polyoxometalates (POMs)-based metal-organic frameworks (MOFs.

1. Introduction. Particulate organic matters (POM) from marine phytoplankton have a mean carbon to nitrogen ratio (C/N) of 106:16 (Redfield, 1958), which might scatter somewhat in some regional areas (Geider and Roche, 2002), but it is considered relatively constant in the global ocean (Karl et al., 1993; Anderson and Sarmiento, 1994).Some nitrogen enriched POM may come from zooplankton and.

Preserving and augmenting POM is a soil carbon storage strategy with lower nitrogen costs, an important advantage given that nitrogen availability is one of the major limiting factors for soil.

The fraction of POM in SOM is (6) f POM-S e d = 1-f MAOM-S e d. Values for the C/N ratios for f MAOM-Sed and f POM-Sed were taken from Cotrufo et al. (2019) and where set to 12.6 for MAOM and to 22.1 for POM. For the original soils from where the sediments were transported from, the same C/N ratios of 12.6 and 22.1 for MAOM and POM were considered.

Soil organic nitrogen (N) is a critical resource for plants and microbes, but the processes that govern its cycle are not well-described. To promote a holistic understanding of soil N dynamics, we need an integrated model that links soil organic matter (SOM) cycling to bioavailable N in both unmanaged and managed landscapes, including agroecosystems. We present a framework that unifies recent.

Light POM can accumulate with no apparent upper limit, but is also vulnerable to factors like warming that enhance decomposition rates (Benbi et al., 2014; Cotrufo et al., 2019). Heavy POM is operationally separated from light POM by density fractionation and is linked with stable soil aggregates (Lavallee et al., 2020).

The purpose of this study was to investigate the carbon and nitrogen isotope composition (δ 13 C and δ 15 N) of POM and zooplankton in Lake Soyang, where the monsoonal climate leads to a characteristic seasonal pattern of a dramatic pulse of turbid runoff to the reservoir during the summer monsoon.

Nitrogen stable isotope (δ 15 N) data of particulate organic matter (POM) from the literature were analyzed to provide an understanding of the variations and controls of δ 15 N POM in lakes at the global scale. The δ 15 N POM variability characterized by seasonal mean, minimum, maximum, and amplitude (defined as δ 15 N POM maximum − δ 15 N POM minimum) from 36 lakes with seasonal data.

Stable carbon and nitrogen isotopic composition of particulate organic matter (POM) were measured for samples collected from the Bering Sea in 2010 summer. Particulate organic carbon (POC) and particulate nitrogen (PN) showed high concentrations in the shelf and slope regions and decreased with depth in the slope and basin, indicating that biological processes play an important role on POM.

The elemental composition of particulate organic matter (POM) dictates the flow of matter via the microbial food web and plays a key role in the biogeochemical cycles of carbon, oxygen, phosphorus, and nitrogen (1, 2).Of particular interest are nitrogen (N) and phosphorus (P), which are essential macronutrients considered to limit marine primary production (3, 4).

For example, "recalcitrant" POM (with high lignin to nitrogen (N) or C:N ratios) can hamper formation of MAOM as compared to "high-quality" POM (low lignin:N or C:N ratios 28).

Elemental ratios of particulate organic matter (POM) are key to linking biogeochemical cycles. The carbon:nitrogen:phosphorus (C:N:P) ratio is often assumed globally constant at Redfield.
