Long-Term Chemical and Organic Fertilization Differently Affect Soil Aggregates and Associated Carbon and Nitrogen in the Loess Plateau of China

Agronomy, 2023
Fertilizer sources may have variable effects on soil aggregation, aggregated-associated C and N, and wheat yield. A 34-year field experiment was performed to evaluate the influences of chemical and organic fertilization on soil aggregates and associated ...

Soil aggregation and aggregate associated organic carbon and total nitrogen under long-term contrasting soil management regimes in loess soil

Journal of Integrative Agriculture, 2015
This study investigated the effects of three contrasting soil management regimes and different nutrient treatments on the distribution of water-stable aggregates (>2, 1–2, 0.5–1, 0.25–0.5, and 0.25 mm) and mean weight diameter (MWD) at 0–10 and 10–20 cm ...

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 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.

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 ...

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.

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.

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

Agronomy
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 ...

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

Geoderma
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.
