During raindrop impact soil, aggregates breakdown and produce finer, more transportable particles and micro-aggregates.
This phenomenon led to soil aggregate breakdown and release of fine soil particles.
Water infiltration rates were reduced during the experiments by a soil structure breakdown, swelling of clay and/or air entrapped in soil samples.
Soil aggregate breakdown is the first key step of splash erosion and is strongly influenced by soil internal forces, including electrostatic, hydration, and van der Waals forces.
The largest soil structure breakdown and infiltration decrease was observed for the Ap horizon of Haplic Luvisol due to the low aggregate stability of the initially well-aggregated soil.
Secondly, sources of spatio-temporal SOC variations are examined, including the lateral transfer of SOC by erosion, soil structural breakdown and land management practices, in the context of RS data and techniques.
The current state of knowledge on the impacts of erosion-induced soil aggregate breakdown and formation, removal of SOC from eroding sites and deep burial of SOC at depositional sites on the mineralization and sequestration of SOC are presented.
In surface waters, sediment and soils, chemical breakdown is mediated by a number of different reactions, including cleavage of molecules by enzymes released by micro-organisms, photolytic and hydrolytic reactions.
This study aimed to investigate the specific effects of interfacial properties on the liquid penetration kinetics in relation to the stability of subcritically water repellent aggregates (4 6.3 mm) from various arable and forest soils against breakdown by slaking.
For example, a S531L mutant was better able to use a variety of β-glucosides, compounds that are likely to be prevalent in the soil owing to breakdown of plant material.
