Soil physical structure and aggregate stability dynamics during pit-mound microrelief development

Trees, Forests and People
Tree uprooting is a prevalent natural disturbance in primary forests, creating pit-mound microrelief that initiates a natural chronosequence of soil recovery.

Investigating the effects of organic and conventional management on soil aggregate stability using X-ray computed tomography

, 2009
Soil aggregate stability is an important measure for assessing soil structural quality. Here we compare stable and unstable soil aggregates from organically and conventionally managed soils that have similar organic matter contents to determine the role ...

Technical Feasibility Study of Autonomous Field Robot‐Based on‐the‐go Assessment of Soil Nutrients Using Ion‐Sensitive Field‐Effect Transistors

Advanced Robotics Research, EarlyView.
Autonomous field robots equipped with ISFET‐based sensors enable rapid, spatially resolved soil nutrient analysis directly in the field. An automated system based on the BoniRob platform is presented for standardized on‐site extraction and measurement of key macronutrients and soil pH.

THE APPLICATION OF DIFFUSION MODELS TO AN AGGREGATED SOIL

Soil Science, 1990
In models on diffusive transport it is necessary to make use of a simplifying description of the geometry of an aggregated soil. It is proposed to use a (hypothetical) model soil consisting of spherical, cylindrical, or flat aggregates. The model aggregates are of different sizes, and each size class occupies a certain fraction of the total volume ...

Soil Inorganic Electron Acceptors and Carbon Substrates Hierarchically Govern Wetland Methanogenesis Temperature Response

Advanced Science, EarlyView.
ABSTRACT Wetlands constitute Earth's largest natural methane (CH4) source, yet projections of their climate feedback remain uncertain due to poorly constrained temperature sensitivity (Q10‐CH4) of microbial methanogenesis. While water table dynamics have been demonstrated to regulate wetland methanogenesis by altering key soil conditions such as ...

Soil microbial parameters and stability of soil aggregate fractions under different grassland communities on the Loess Plateau, China

, 2009
Over-grazing and large-scale monocultures on the Loess plateau in China have caused serious soil erosion by water and wind. Grassland revegetation has been reported as one of the most effective counter measures.

Effects of soil aggregate stability on soil N following land use changes under erodible environment

, 2018
Soil nitrogen (N) dynamics have considerable effects on the terrestrial carbon cycle, and land use changes could affect soil N through impacts on soil aggregate stability.
