Some factors affecting clay dispersion and aggregate stability in selected soils of Nigeria
aggregate stability aggregated clay chemical extractants tropics water-dispersible clay
2008/11/24
Using 22 soil samples from Nigeria, comprising Alfisols, Entisols, Inceptisols, Ultisols and Vertisols with 77- 676 g kg-1 clay, we studied the effect of various treatments on clay dispersion. Aggrega...

0.5 mm) were found to negatively relate with splash and sediment yield. The measured and calculated erodibility ratings did not agree with the ranking of the soils. However, such parameters as exchang...
Reduction in organic matter fractions and structural stability following cultivation of tropical forests in Ethiopia and Nigeria
organic matter aggregate stability tropical soils
2008/11/12
The objectives of this study were: to assess changes in the organic matter (OM) fractions of the surface layer (0-20 cm) of the forested Ethiopian and Nigerian soils following their conversion to arab...
Shrink-swell potential of flood-plain soils in nigeria in relation to moisture content and mineralogy
coefficient of linear extensibility mineralogy principal component flood-plain soils of Nigeria moisture content
2008/11/12
The shrink-swell hazard is an important soil factor that affects infrastructural development of the soil. The shrink-swell potential of some flood-plain soil profiles was determined using the coeffici...
Soil strength of some Central Eastern Nigeria soils and effect of potassiumand sodium on their dispersion
Atterberg limits coefficient of linear extensibility clay dispersion Nigeria
2008/11/11
Five soils with variable clay contents were studied with the objective of describing their physical properties and the influence of NaCl and KCl on their dispersion. The soils were analyzed for parti...
Structural stability of exposed gully wall in Central Eastern Nigeria as affected by soil properties
gully wall soil properties aggregate stability slumping permeability moisture content
2008/11/11
We studied the soil stability of a gully wall in a gully erosion prone area of Central Eastern Nigeria. The objective was to investigate the physicochemical properties of the gully wall soils and to ...
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
