Hexosamines in Soil Aggregates [PDF]

Nature, 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 ...

Effects of free atmospheric CO₂ enrichment (FACE), N fertilization and poplar genotype on the physical protection of carbon in the mineral soil of a polar plantation after five years [PDF]

, 2006
International audienceFree air CO2 enrichment (FACE) experiments in aggrading forests and plantations have demonstrated significant increases in net primary production (NPP) and C storage in forest vegetation.

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

Ecosphere, 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.

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

Ecological 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.

Experimental Setup for Splash Erosion Monitoring—Study of Silty Loam Splash Characteristics [PDF]

, 2020
An experimental laboratory setup was developed and evaluated in order to investigate detachment of soil particles by raindrop splash impact. The soil under investigation was a silty loam Cambisol, which is typical for agricultural fields in Central ...

Unveiling the age and origin of biogenic aggregates produced by earthworm species with their NIRS fingerprint in a subalpine meadow of Central Pyrenees.

PLoS ONE, 2020
In this study the near-infrared reflectance (NIR) spectra signals (750-2,500 nm) of soil samples was compared with the NIR signals of the biogenic aggregates produced in the lab by three earthworm species, i.e., Aporrectodea rosea (Savigny 1826 ...

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

Open 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.

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

Guangxi 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.

Combination of techniques to quantify the distribution of bacteria in their soil microhabitats at different spatial scales [PDF]

, 2018
To address a number of issues of great societal concern at the moment, like the sequestration of carbon, information is direly needed about interactions between soil architecture and microbial dynamics.
