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.

The stability of soil aggregates in tilled fallow areas in Hyderabad district, Pakistan

Journal of Water and Land Development, 2015
Arid areas are particularly susceptible to soil erosion due to long dry periods and sudden heavy downpours. This study investigates the aggregate size distribution and aggregate stability of twelve tilled fallow areas of Hyderabad district, Sindh ...

Assessing soil aggregate stability by measuring light transmission decrease during aggregate disintegration

Soil and Water Research
Advancements in technology have recently enabled to assess soil aggregate stability (SAS) using digital devices. To address the need for a faster and more efficient method of measuring SAS, we have developed a simple yet effective approach using a ...

Performance evaluation of hot mix asphalt (HMA) using glass fiber as a partial replacement of fine aggregate [PDF]

Archives of Civil Engineering
Hot Mix Asphalt mixtures are often used as the top layer of pavement structures to build roads worldwide. Hot Mix Asphalt (HMA) mixtures combine bitumen and aggregate to produce roads.

The relative contributions of soil hydrophilicity and raindrop impact to soil aggregate breakdown for a series of textured soils

International Soil and Water Conservation Research, 2022
Soil aggregate breakdown is the first key factor that causes soil erosion. At present, research on the mechanisms of soil aggregate breakdown during rainfall is common.

Aggregate Stability and Balanced-Budget Rules [PDF]

Journal of Money, Credit and Banking, 2014
It has been shown that under perfect competition and a Cobb-Douglas production function, a basic real business cycle model may exhibit indeterminacy and sunspot fluctuations when income tax rates are determined by a balanced-budget rule. This paper introduces in an otherwise standard real business cycle model a more general and data coherent class of ...

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.

Sodium Diisopropylamide: Aggregation, Solvation, and Stability [PDF]

Journal of the American Chemical Society, 2017
The solution structures, stabilities, physical properties, and reactivities of sodium diisopropylamide (NaDA) in a variety of coordinating solvents are described. NaDA is stable for months as a solid or as a 1.0 M solution in N,N-dimethylethylamine (DMEA) at -20 °C.

Interactive Effects of Tillage and Soil Depth on Soil Aggregate Stability in Relation to Soil Properties and Glomalin-Related Soil Proteins

Biology
Tillage practices influence soil structural stability by modifying the soil physicochemical environment and biological processes. However, the relationships among tillage, soil depth, Glomalin-related soil proteins (GRSP), and soil aggregate stability ...

The aggregate stability of the soil in respect to the uniform aggregate stability indicator

Acta Agraria Debreceniensis, 2007
Soil structure and its quality are fundamental properties because they control many processes in soils. Tillage, crop and other factors influence soil structure. Efficient protection of it needs indication of changes in soil structure. A new Normalized Stability Index proposed by Six et al.
