Low pH inhibits soil nosZ without affecting N2O uptake
Nitrous oxide (N2O) is an important greenhouse gas. Soils are the main source and an important sink of N2O. Gross rates of soil N2O emission and uptake determine the net flux and concentration of N2O in the atmos...

Liming and nitrification inhibitor affects crop N uptake efficiency and N loss through changing soil N processes
The form of inorganic N in soil is governed by N transformations, but the relationship between the soil N transformation dynamics and the N uptake by plants is unclear. The effect of liming and nitrification i...

Pathways of soil N2O uptake, consumption, and its driving factors: a review
Nitrous oxide (N2O) is an important greenhouse gas that plays a significant role in atmospheric photochemical reactions and contributes to stratospheric ozone depletion. Soils are the main sources of N2O emission...

Hydropower reservoirs enhanced the accumulation of heavy metals towards surface sediments and aggravated ecological risks in Jiulong River Basin, China
In complex watersheds with multiple types of waterbodies, the effect of river damming on the distribution pattern of heavy metals in sediments and their potential ecological risks are inconsistent, leading to ...

Fine-scale remobilization of phosphorus by rooted macrophytes (Phragmites australis) growth in lake sediments: evidence from a holistic growth period simulation study
Aquatic vegetation serves an important structuring function in shallow freshwater ecosystems. Although increasing evidence indicates that sediment-associated phosphorus (P) is mobilized by aquatic macrophytes ...

Inhibitory Effects of Different Types and Doses of Herbicides on Soil Nitrification Potentials
To elucidate the inhibitory effects of different herbicides on soil nitrification, eight widely used herbicides, i.e., acetochlor, atrazine, dicamba, isoproturon, paraquat, puma, tribenuron-methyl, and 2,4-dic...

Open AccessSoil N transformation mechanisms can effectively conserve N in soil under saturated conditions compared to unsaturated conditions in subtropical China
The connection between moisture and nitrogen (N) transformation in soils is key to understanding N losses, particularly nitrate (NO3−) losses, and also provides a theoretical framework for appropriate water manag...

The fate of urea nitrogen applied to a vegetable crop rotation system
To investigate the fate of urea nitrogen (N) applied to vegetable fields, three N rates, N0 (0 kg N/ha), N1(225 or 240 kg N/ha) and N2 (450 or 480 kg N/ha) were applied to a rotation system. Nitrogen fertiliz...
