Indications of nitrogen-limited methane uptake in tropical forest soils

متن کاملEffects of long-term nitrogen fertilization on the uptake kinetics of atmospheric methane in temperate forest soils.
To determine whether repeated, long-term NH(4) (+) fertilization alters the enzymatic function of the atmospheric CH(4) oxidizer community in soil, we examined CH(4) uptake kinetics in temperate pine and hardwood forest soils amended with 150 kg N ha(-1) y(-1) as NH(4)NO(3) for more than a decade. The highest rates of atmospheric CH(4) consumption occurred in the upper 5 cm mineral soil of the ...
متن کاملSynergistic effects of dissolved organic carbon and inorganic nitrogen on methane uptake in forest soils without and with freezing treatment
There is limited knowledge about how the interaction of dissolved organic carbon (DOC) and inorganic nitrogen (N) released into the soil just after freezing can affect methane (CH4) uptake in forest soils. Here, we present how freezing treatment and glucose, as a DOC source, can affect the roles of NH4(+)-N and NO3(-)-N in inhibiting soil CH4 uptake, by using soil-core incubation experiments. A...
متن کاملImmediate and long-term nitrogen oxide emissions from tropical forest soils exposed to elevated nitrogen input
Tropical nitrogen (N) deposition is projected to increase substantially within the coming decades. Increases in soil emissions of the climate-relevant trace gases NO and N2O are expected, but few studies address this possibility. We used N addition experiments to achieve N-enriched conditions in contrasting montane and lowland forests and assessed changes in the timing and magnitude of soil N-o...
متن کاملEcology of Nitrogen Fixing, Nitrifying, and Denitrifying Microorganisms in Tropical Forest Soils
Soil microorganisms play important roles in nitrogen cycling within forest ecosystems. Current research has revealed that a wider variety of microorganisms, with unexpected diversity in their functions and phylogenies, are involved in the nitrogen cycle than previously thought, including nitrogen-fixing bacteria, ammonia-oxidizing bacteria and archaea, heterotrophic nitrifying microorganisms, a...
