Study of Saturated Hydraulic Conductivity Variations in Different Aggregate Size Distributions in an Agricultural Soil

علوم آب و خاک, 2019
Saturated hydraulic conductivity (Ks) is one of the most important soil physical characteristics that plays a major role in the soil hydrological behaviour. It is mainly affected by the soil structure characteristics.

Soil aggregation, aggregate stability, organic carbon and nitrogen in different soil aggregate fractions under forest and shrub vegetation on the Loess Plateau, China

, 2010
Revegetation has been reported as one of the most effective counter measures to reduce soil and water erosion on the Loess plateau in China. Soil aggregate stability and the distribution of organic carbon and nitrogen in different aggregate fractions ...

Table_1_Mixed planting improves soil aggregate stability and aggregate-associated C-N-P accumulation in subtropical China.DOCX

, 2023
Research on the variations in soil aggregate stability and ecological stoichiometry at aggregate scales by stand type is of great significance in investigating the distribution, limitation, balance, and cycling of organic carbon, nitrogen, and phosphorus

Aggregate price shocks and financial instability: a historical analysis [PDF]

This paper presents empirical evidence on the hypothesis that aggregate price disturbances cause or worsen financial distress. We construct two annual indexes of financial conditions for the United States covering 1790-1997, and estimate the effect of ...

Soil - Temporal variation in aggregate stability [PDF]

, 1995
A soil's ability to resist structural deterioration is one of its most important physical properties. An aggregate, a unit of soil structure, is a cluster or coherent association of primary particles (sand, silt, or clay) that has been cemented or bound ...

Changes of Soil Aggregate Stability as a Result of the Effect of Freeze-thaw Cycles [PDF]

, 2015
The objective of the present research was to assess the changes in soil erodibility during the non-vegetation period as one of the factors affecting the snowmelt erosion.

Soil Aggregate Stability Under Freeze–Thaw Cycles in Mollisols as Evidenced by ¹⁵N Distribution

Agronomy
Freeze–thaw cycles (FTCs) influence soil nitrogen (N) dynamics and soil aggregate stability. However, the driving mechanism affecting aggregate stability from the combined perspective of N components and N distribution by 15N tracing technology in both ...

On the stability of utilitarian aggregation

Theory and Decision
Abstract In the context of aggregating von Neumann-Morgenstern utilities, we show that bounded violations of the Pareto conditions characterize aggregation rules that are approximately utilitarian. When a single utility function is intended to represent the preference judgments of a group of individuals and the Pareto principles are ...
