Geoderma, 2019
Various thermochemical conversion technologies can be applied in producing biochar from a wide range of raw materials. We studied the chemical quality of 10 different biochars produced via torrefaction (TOR), slow pyrolysis (SP), or hydrothermal ...

Studies of soil organic carbon (SOC) and iron oxides are crucial for understanding soil aggregate formation and stability in paddy–upland rotation systems. Many of these soils contain large amounts of SOC and iron oxides, which may be lost due to changes

Tillage-induced effects on SOC through changes in aggregate stability and soil pore structure.
Science of the Total Environment, 2019Soil structure plays a key role in soil organic carbon (SOC) dynamics. To determine how soil structure and aggregate affects SOC, we collected undisturbed soil cores of 0-5 cm layer (Typic Hapludoll) at an experimental site in Northeast China.

Soil Aggregates — Formation and Stability
1990The first requirement for the efficient production of most agricultural crops is that sufficient water derived from rainfall or irrigation is accepted by the soil. Otherwise, water is not only wasted, but erosion may result. The second requirement for crops other than rice is that waterlogging does not occur, and that soil aggregates at field capacity ...

Aggregation and Aggregate Stability in Forest and Range Soils
Soil Science Society of America Journal, 1988Abstract A simple method for measuring aggregation and aggregate stability across soils of widely varying structure and texture is presented. The method uses standard techniques of particle‐size analysis to measure yield of fine particles (<26‐µm estimated spherical diam.) after three types of dispersion treatments: shaking in ...

Aggregate stability of soils informs about their relative strengths against erosive forces and mechanical disruption; however, the many methods of assessment are not of equal potential in discriminating management effects.
