Quantifying the contribution of the root system of alpine vegetation in the soil aggregate stability of moraine

International Soil and Water Conservation Research, 2017
One fifth of the world's population is living in mountains or in their surrounding areas. This anthropogenic pressure continues to grow with the increasing number of settlements, especially in areas connected to touristic activities, such as the Italian ...

Effects of freeze-thaw cycles on the size distribution and stability of soil aggregate in the permafrost regions of the Qinghai-Tibetan Plateau

Environmental Research Communications, 2023
As the basic units of soil structure, soil aggregate is essential for maintaining soil stability. Intensified freeze–thaw cycles have deeply affected the size distribution and stability of aggregate under global warming.

Greater mineral and aggregate protection for organic carbon in the soil amended by weathered coal than by biochar: Based on a 3-year field experiment

Geoderma, 2023
Soil carbon pool stability plays an important role in reaching carbon neutrality and mitigating global warming. Applying soil amendments is a practical strategy in agricultural production to improve soil environment.

Soil aggregate structure, stability, and stoichiometric characteristics in a smelter-impacted soil under phytoremediation

Frontiers in Environmental Science, 2022
Smelter-impacted soils often result in soil degradation and the destruction of the soil structure. Although soil aggregate typically plays a crucial role in soil structure, the influence of phytoremediation on soil aggregate structure stability and ...

Arbuscular mycorrhizal hyphal networks and glomalin-related soil protein jointly promote soil aggregation and alter aggregate hierarchy in Calcaric Regosol

Geoderma
The Loess Plateau of China (LPC) is one of the most severely eroded areas in the arid and semi-arid regions of northern China. Improving soil aggregate stability and hierarchy in Calcaric Regosol is vital for mitigating soil erosion.

The Effect of Zeolite on Aggregate Stability Indices

مجله آب و خاک, 2016
Introduction: Soil structural stability affects the profitability and sustainability of agricultural systems. Particle size distribution (PSD) and aggregate stability are the important characteristics of soil. Aggregate stability has a significant impact

Gas Displacement and Aggregate Stability of Soils [PDF]

Soil Science Society of America Journal, 1985
Abstract When surface soils are dry, O 2 and N 2 are adsorbed on the external mineral surfaces. In the process of wetting the soil, water molecules displace the adsorbed O 2 and N

Investigating the effects of organic and conventional management on soil aggregate stability using X-ray computed tomography

, 2009
Soil aggregate stability is an important measure for assessing soil structural quality. Here we compare stable and unstable soil aggregates from organically and conventionally managed soils that have similar organic matter contents to determine the role ...

The Influence of Microbiology on Soil Aggregation Stability

IOP Conference Series: Materials Science and Engineering, 2020
Abstract In the present study, this work investigated the effects of bacteria (Bacillus sp.) decay and biological aggregating factors (organic matter, microbial calcium carbonate precipitation) at various steps on soil aggregate stability. Experiments carried out at different cultivation time 2, 5, and 8 weeks.
