Land-use shapes the composition and stability of soil water-stable aggregates in a plateau agro-pastoral ecotone [PDF]

PeerJ
Background The northeastern Tibetan Plateau is a typical agro-pastoral ecotone that experiences frequent land-use changes. Maintaining stable soil aggregates in this region is key to protecting the environment and supporting food production on the ...

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 ...

Temporal changes in wet aggregate stability [PDF]

, 1992
Aggregate stability, a property that influences a soil's erodibility and hydraulic characteristics, has been shown in previous investigations (e.g., Bullock et al., 1988) to vary over time for some northwestern U.S. soils.

Short-term dynamics of soil aggregate stability in the field

, 2014
Aggregate stability is a key property affecting the movement and storage of water, seedling emergence, and soil sensitivity to erosion. Many studies have shown that aggregate stability changes through time.

Divergent responses of aggregate breakdown by slaking to nitrogen forms in solution for contrasting soil types

Geoderma
Aggregate stability strongly affects many soil processes and is critical to maintain sustainable agriculture. Aggregate breakdown is controlled by the interaction between soil intrinsic properties and solution characteristics.

Comparison and Evaluation of SLAKEs and Cornell Aggregate Stability Tests

, 2023
Soil aggregation is the binding of multiple soil particles into secondary groupings. The stability of an aggregate refers to the tendency of the soil particles to remain bound under different environmental conditions. Aggregate stability is one aspect of

Influence of aggregate gradation on hma mixes stability

Romanian Journal of Transport Infrastructure, 2015
The load transfer capacity of pavements is to a great extend influenced by aggregates. About 85% of the total volume of hot mix asphalt (HMA) mixtures consists of aggregates; thus, they are greatly influenced by aggregate properties like angularity ...

Stability and bounds in aggregate scheduling networks

, 2008
We study networks of FIFO nodes, where flows are constrained by arrival curves. A crucial question with these networks is: Can we derive a bound to the maximum delay that a packet can experience when traversing the network, and to the maximum queue size at each node?
