No-Tillage Improvement of Nitrogen Absorption and Utilization in a Chinese Mollisol Using 15N-Tracing Method

open access: yesAtmosphere, 2022
To better understand the mechanism of nitrogen (N) distribution, absorption, utilization and loss in fertilizer under different tillage practices, a study was conducted to quantitatively explore the fate of fertilizer N in the soil–plant–atmosphere using

Studies on dissipation of thiamethoxam insecticide in two different soils and its residue in potato crop

open access: yesPlant, Soil and Environment, 2014
The dissipation patterns of thiamethoxam insecticide at two different rates (12.5 and 25 µg/g) in both silty clay loam and loam soils were studied. The half lives of thiamethoxam were in the range of 15.0 to 18.8 days in silty clay loam and 20.1 to 21.5 ...

The Influence of Harbin Forest–River Ecological Corridor Construction on the Restoration of Mollisols in Cold Regions of China

open access: yes, 2022
Artificial ecological corridors (AECs) are internationally approved ecological restoration and climate mitigation strategies. The width and recovery time indices of AECs directly affect the restoration efficiency of degraded soil nutrients.

Cover crops effects on soil hydraulic properties in two contrasting Mollisols of the Argentinean Pampas region [PDF]

open access: yes, 2023
Decreasing physical quality of Mollisols in the Argentinean Pampas region is observed due to simplified crop rotations. The main objective of this work was to evaluate the effects of cover cropping management on soil water capture, transport, and storage
