Geologic records reveal that magnetic field strength and oxygen levels rise and fall together, implying deep-Earth processes ...

Previously, inverse nitrogen isotope effects in atrazine degrdn. by Arthrobacter aurescens TC1 (i) delivered highly characteristic (13C/12C, 15N/14N) fractionation trends for pathway identification ...

Nitrogen dioxide, or NO 2, is a gaseous air pollutant composed of nitrogen and oxygen and is one of a group of related gases called nitrogen oxides, or NO x. Nitrogen dioxide forms when fossil fuels ...

Bound amino compounds (amino acid and amino sugar polymers) comprise a significant proportion (∼40%) of soil organic nitrogen and therefore represent an essential source of nitrogen for plant and ...

Keywords: waxy corn, cover crop, yield, nitrogen use efficiency, path analysis. Citation: Sun M, Zhang L, Zhou J, Liu Z, Peng C, Jia Z, Lv Y and Wang Y (2025) Leveraging cover crop functional traits ...

These signatures preserve a record of how nitrogen was cycled in ancient oceans. By tracing changes in nitrogen isotope ratios, scientists can reconstruct how oxygen levels shifted over time. The team ...
