Effects of nitrogen-fixing tree species Acacia mangium on particle size distribution and stability of soil aggregates in Eucalyptus grandis × urophylla plantations

open access: yesGuangxi Zhiwu
Soil aggregates are the basic unit of soil structure. The stability of soil aggregates is an important indicator for evaluating soil structure and soil fertility.

Effects of shrub encroachment on soil aggregates and organic carbon vary in different grasslands in Inner Mongolia, China

open access: yesEcosphere, 2021
Widespread shrub encroachment in grasslands can lead to changes in soil aggregates and soil organic carbon (SOC), especially in deep soils. Soil aggregates physicochemically protect SOC and thus affect soil carbon sequestration.

Soil Aggregates and Water Infiltration Performance of Different Water and Soil Conservation Measures on Phaeozems Sloping Farmland in Northeast China

open access: yesAgronomy
The enhancement of soil erosion resistance via soil and water conservation practices is a necessary venture in the modern agricultural industry. Soil infiltration performance, as a necessary indicator of erosion resistance, is closely related to soil ...

Effect of long-term tillage on soil aggregates and aggregate-associated carbon in black soil of Northeast China.

open access: yesPLoS ONE, 2018
Soil tillage can affect the stability and formation of soil aggregates by disrupting soil structure. Frequent tillage deteriorates soil structure and weakens soil aggregates, causing them to be susceptible to decay.

Effects of thinning on soil aggregation, organic carbon and labile carbon component distribution in Larix principis-rupprechtii plantations in North China

open access: yesEcological Indicators, 2022
The forest ecosystem is the ecosystem with the largest terrestrial carbon pool in the world. Afforestation, cutting and tending mutually affect the forest carbon source and the carbon sink.

Dissolved organic matter characteristics of soil aggregates on slopes covered by natural successional vegetations with different root structures

open access: yesGeoderma
Vegetation restoration is a critical measure to control soil erosion and improve soil quality. However, limited research has examined how dissolved organic matter (DOM) within soil aggregates changes during natural vegetation succession.

Microbial community structure and carbon transformation characteristics of different aggregates in black soil [PDF]

open access: yesPeerJ
Background Previous research on whole-soil measurements has failed to explain the spatial distribution of soil carbon transformations, which is essential for a precise understanding of the microorganisms responsible for carbon transformations.

Study on the stabilization mechanism of aeolian sandy soil formation by adding a natural soft rock

open access: yesOpen Geosciences, 2023
The study of the distribution of cementitious materials in soil aggregates is important for understanding the formation of aggregates in soil due to the addition of soft rock rich in clay.

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

open access: yesFEBS Letters, EarlyView.
Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

Hexosamines in Soil Aggregates [PDF]

open access: yesNature, 1963
RECENT experiments at this Station on water-stable soil aggregates in a Bridgehampton silt loam have indicated that quantity of soil organic matter is not a reliable index of efficiency in the formation and stabilization of aggregates1,2. These investigations involved soils in frames that had been in redtop–potato and red clover–potato rotations for a ...
