Microplastics change the leaching of nitrogen and potassium in Mollisols

Science of The Total Environment, 2023
Nowadays, the dynamics of nutrients leaching from the soils and their driving mechanism have been focused on, however, it is still unclear how microplastics (MPs) influence the nutrients' leaching in soils. In this study, five concentrations (w/w, 0.0 %, 0.5 %, 1 %, 2 %, 3 %) and three sizes of MPs of polyethylene (PE) (0.15-0.36 mm, 0.36-0.60 mm and 0.

Effects of long-term cropping regimes on SOC stability, soil microbial community and enzyme activities in the Mollisol region of Northeast China

, 2021
Retaining carbon in cultivated soils is an important mechanism to mitigate climate change and to maintain the sustainability of agricultural ecosystems. Characterization of the soil microbial community was an early means to quantify the increase in soil ...

Physically separated soil organic matter pools as indicators of carbon and nitrogen change under long-term fertilization in a Chinese Mollisol.

Environmental Research, 2022
Isolation and quantification of soil organic matter (SOM) pools under the influence of management practices is needed for assessing the changes in soil fertility.

Soil water retention dynamics in a Mollisol during a maize growing season under contrasting tillage systems

Soil and Tillage Research, 2021
A Soil water retention curve (SWRC) provides pore structure information and is usually measured in the laboratory on soil cores. In field, the dynamics of SWRC is affected by pore structure changes due to tillage operations and wet-drying cycles (WDs ...

Hydric Soil Indicators in Mollisol Landscapes

2000
Mollisols are mineral soils that usually develop under prairie vegetation. They are characterized by relatively thick, dark surface horizons resulting from an increased organic matter content, which can present problems for hydric soil identification due to the lack of visible iron-based redoximorphic features (Chapters 7 and 8) in the upper part of ...

Soil erosion‐induced decline in aggregate stability and soil organic carbon reduces aggregate‐associated microbial diversity and multifunctionality of agricultural slope in the Mollisol region

Land Degradation & Development
Soil erosion has become a serious ecological problem hindering the agricultural and economic development in Northeast China. Soil aggregates are basic units that regulate soil fertility and microbial activity.

Fifteen-year no tillage of a Mollisol with residue retention indirectly affects topsoil bacterial community by altering soil properties

, 2021
Soil microbes play an important role in nutrient cycling in agricultural soils and can be influenced by tillage. Conservation tillage aims to reduce energy inputs and conserve soil and water by decreasing disturbance of soil and returning a portion of ...

Long‐term manure application enhances organic carbon and nitrogen stocks in Mollisol subsoil

Land Degradation & Development, 2022
Subsoils contain half of the total soil organic carbon (SOC) that is supposed to be relatively more persistent than that present in the topsoil. Improving SOC and total nitrogen (TN) stocks in croplands is crucial to mitigate climate change and ensuring ...
