Possible Interaction: Manganese and Nitrogen

“ Anthropogenic nitrogen may also affect manganese concentrations in groundwater.”

“ Nitrogen addition decreased plant community-level biomass weighted (hereafter referred to as community-level) Fe concentration but increased Mn concentration, with a greater effect under (NH4)2SO4 addition.”

“Our results revealed that Mn (0.25 mg g-1 ) addition significantly increased WS decomposition, and enhanced the release of carbon and nitrogen.”

“The introduction of Mn into β-TCP significantly improved the scavenging of oxygen radicals and nitrogen radicals , demonstrating that Mn-TCP bioceramics might have antioxidant properties.”

“ Nitrogen addition enhanced the uptake of N, P, S, K, Mn , Cu and Zn by plants, while inhibited plant Fe uptake, but with no effect on the uptake of Ca or Mg.”

“… nitrogen (N) addition resulted in surface soil acidification and decreased acid buffering capacity, increased … (C), N, phosphorus (P), sulfur (S) and DTPA-extractable iron (Fe), manganese (Mn), and copper (Cu) contents, depleted the sum of base cations calcium (… (K) and sodium (Na), decreased the diversity of soil microbial community.”

“The electron distribution of MnOx/semi-coke catalysts and the electron mobility between manganese and oxygen species are improved by nitrogen doping.”

“These high performances are attributed to the synergistic effects of the CoP nanosheets with intrinsic activity, the graphitic carbon and the controllable electronic structure doped by Mn and N elements.”

“ Nitrogen addition significantly decreased exchangeable Ca by up to 33% in large and small macroaggregates and exchangeable Mg by up to 27% in three aggregates but significantly increased extractable Fe, Mn and Cu concentrations (by up to 262%, 150%, and 55%, respectively) in all aggregate size classes.”

“The nitrogen content of fractionated rubber fractions from rubber particles washed for five times increased with increasing Mn.”
