Characterisation of soil aggregate stability by ultrasonic dispersion
ultrasonic dispersion soil aggregate stability soil particle dispersion
2008/11/24
Ultrasonic soil aggregate stability (USAS) of 5 European soils was investigated in ultrasonic dispersion tests, studying mass fractions of macroaggregates at different absorbed specific energy levels....

Influence of the microbiological activity on the soil aggregate stability
microbiological activity soil aggregate stability
2008/11/18
The influence of the microbiological activity on the soil aggregate stability of a silty Chernozem was investigated by promoting the microbial activity through D-glucose solution. After 2 weeks of inc...
Strength regain in soil aggregate beds by swelling and shrinkage
precompression stress cohesion angle of friction soil structure bulk density
2008/11/11
Strength regain in aggregate beds as a consequence of wetting and drying cycles was studied in two Andisols and one Mollisol from Chile, collected at two depths (0-10 and 40-60 cm). In the Mollisol, ...
The use of some soil aggregate indices to assess potential soil loss in soils of south-eastern nigeria
soil loss erodibility aggregate indices flocculation texture
2008/11/11
GMDWD while organic carbon, % clay content and Fe.O. are some soil characteristics that predict the potential of these soils to erode fairly accurately. Dispersion and flocculation are shown to be in...
