The relative contributions of soil hydrophilicity and raindrop impact to soil aggregate breakdown for a series of textured soils

International Soil and Water Conservation Research, 2022
Soil aggregate breakdown is the first key factor that causes soil erosion. At present, research on the mechanisms of soil aggregate breakdown during rainfall is common.

Conversion of alpine pastureland to artificial grassland altered CO2 and N2O emissions by decreasing C and N in different soil aggregates [PDF]

PeerJ, 2021
Background The impacts of land use on greenhouse gases (GHGs) emissions have been extensively studied. However, the underlying mechanisms on how soil aggregate structure, soil organic carbon (SOC) and total N (TN) distributions in different soil ...

Land-use shapes the composition and stability of soil water-stable aggregates in a plateau agro-pastoral ecotone [PDF]

PeerJ
Background The northeastern Tibetan Plateau is a typical agro-pastoral ecotone that experiences frequent land-use changes. Maintaining stable soil aggregates in this region is key to protecting the environment and supporting food production on the ...

Variation in Soil Aggregate Stability Due to Land Use Changes from Alpine Grassland in a High-Altitude Watershed

Land, 2023
Land use change affects soil aggregate composition and stability, which impacts soil structure and health. To reveal how land use change impacted soil aggregates of alpine grassland in a high-altitude watershed, soil samples from 161 sites including ...

Regulation of soil organic carbon stock with physical properties in alluvial soils of Bihar

Environment Conservation Journal, 2022
Soil temperature and water content govern the breakdown of soil organic matter (SOM), which has a large impact on SOC storage. Apparently soil organic carbon is an excellent indicator of soil health.

Composition of Soil Bacterial and Nematode Communities within Soil Aggregates in a Kiwifruit Orchard under Cover Crop Treatment

Agronomy, 2023
Soil, which exhibits difference in nutrient contents and aggregate sizes, provides spatially distinct habitats for biota. Cover crops influence the compositions of soil organism communities, playing an indispensable role in regulation of underground food

Interacting Effects of Land Use Type, Soil Attributes, and Environmental Factors on Aggregate Stability

Land, 2023
Soil erosion and surface pollution near reservoirs can adversely affect water quality and safety. Soil aggregate stability is an important predictor of soil water loss and erosion resistance that is strongly influenced by land use.
