The role of conservation soil management on soil and water protection at different spatial scales [PDF]

, 2006
Agriculture has a direct impact on the soil environment, altering soil properties, surface characteristics and erosion risk. This has led to a move away from conventional tillage to the adoption of conservation practices, aiming to minimise soil ...

Aggregate pore and shape properties were more strongly correlated to soil organic carbon in large aggregates: Evidence from a long-term management-induced soil carbon gradient

Geoderma
The interplay between soil structure and soil organic carbon (SOC) is complex and affects key soil functions. There is limited knowledge on how this relationship changes with the size of the structural unit studied.

Emerging threats to the stability of soil aggregates [PDF]

, 2021
Soil aggregates are clusters of soil particles, supporting the soil physical structure. Soil aggregation is key to the functions of ecosystem, including aeration, water infiltration and storage, nutrient cycling, and the pore system. This doctoral work

Fractal Dimension of Coastal Soil Aggregates and Its Relationship with Physical and Chemical Soil Properties

Guan'gai paishui xuebao, 2021
【Objective and objective】 Soil aggregate is a function unit commonly used to describe the impact of soil structure on soil fertility and quality. It is temporally dynamic, modulated by a myriad of biotic and abiotic factors such as wetting-drying cycles ...

Fungal Traits Important for Soil Aggregation [PDF]

Frontiers in Microbiology, 2020
Soil structure, the complex arrangement of soil into aggregates and pore spaces, is a key feature of soils and soil biota. Among them, filamentous saprobic fungi have well-documented effects on soil aggregation. However, it is unclear what properties, or traits, determine the overall positive effect of fungi on soil aggregation. To achieve progress, it

THE RELATIONSHIP OF POLYSACCHARIDES TO SOIL AGGREGATION [PDF]

Canadian Journal of Soil Science, 1963
Studies were conducted on two soil types to determine whether variations in level of aggregation, induced by adding wheat straw were accompanied by significant changes in the polysaccharide content of the soils.The addition of finely ground wheat straw to the soils, followed by varying periods of incubation, markedly improved the level of aggregation ...

Stoichiometric characteristics drive the soil aggregate stability after 5 years of vegetation restoration in China

Frontiers in Ecology and Evolution, 2023
Soil stoichiometric characteristics and aggregate stability are affected by vegetation restoration in degraded land. Yet, it is not known that how the aggregate stability is related to soil stoichiometric characteristics under different vegetation ...

Saving the face of soil aggregates [PDF]

Global Change Biology, 2019
Hierarchy levels and building units of micro- and macroaggregates and related separation methods. The hierarchy levels (left arrow) are inversely related to the energy necessary for the disruption (right arrow).

Soil Enzyme Activities Affect SOC and TN in Aggregate Fractions in Sodic-Alkali Soils, Northeast of China

Agronomy, 2022
Soil enzymes strongly affect soil organic carbon (SOC) and nitrogen (TN) storage. However, few studies have focused on their relationships in aggregates, especially in sodic-alkali agricultural fields.

Relationship between soil carbon sequestration and the ability of soil aggregates to transport dissolved oxygen [PDF]

, 2021
A key finding in soil carbon studies over the past decade is that soil organic carbon (SOC) stabilization is not controlled by its molecular complexity or adsorption to clay, but by its physicochemical protection including occlusion in aggregates and ...
