This contributed to accumulation of soil nutrients. Soil quality index results showed that the soil quality index of abandoned farmland in 5–10 cm and 10–20 cm soil layer is the highest among the eight types of land, therefore, the 5–10 cm and 10–20 cm soil layers of abandoned ...

Surrounding rock soilIt is importance to understand the correlation between the physicochemical properties of different surrounding rock soil and microbial communities in Fushun western opencast mining for the ecological restoration of land after mine closure. In this study, two layers of soil samples ...
Mining subsidence in the Shanxi-Shaanxi-Inner Mongolia border region of northwestern China has caused ecological damage by strongly disturbing the surface soil. To explore the mechanism by which mining subsidence influences soil water and
This paper presents an experimental investigation on the effect of freeze–thaw cycling on expansive soil slopes with different initial moisture contents. Clay soil from Weifang, China, was remolded and selected to build the expansive soil slope for the
in the example of Nankai Trough, as the depressurization method reduces the pore water pressure from approximately 13 MPa to the bottom hole pressure of 3 MPa, maximizing gas productivity, there is a concern that the effective stress born by the soil skeleton will increase, resulting in consolida...
Two subsamples were collected from each layer using a soil core sampler (AMS Inc., USA); 100 g of each subsample was obtained and thoroughly mixed. All samples were kept in ice boxes and transported from the distilleries to the laboratory at low temperatures (transportation time <48 h). ...
Considering the large amount and high frequency application of concentrated fertilizer nitrogen in the Black Soil Region of Northeast China, the current laboratory/field simulation study aimed to explore the pollution risk of added nitrogen in black soil
After comparing the moisture storage levels in the different soil layers at depths of 0–200 cm, we found that the water increases occurred mainly at depths of 0–100 cm, whereas the spatial and temporal changes in moisture storage at depths below 100 cm were relatively small, and ...
