Assessing the compaction susceptibility of South African forestry soils. II. Soil properties affecting compactibility and compressibility
CW Smith, MA Johnston, S Lorentz - Soil and Tillage Research, 1997 - Elsevier
Factors affecting the compaction susceptibility of South African forestry soils were assessed.
Two traditional measures of compaction susceptibility were used: maximum bulk density
(ρmbd) determined by the standard Proctor test, defined compactibility, and the compression
index using a simple uni-axial test, defined compressibility. Soils were chosen from a broad
range of geological and climatic regions and they varied greatly in texture (8 to 66 g 100 g−
1 clay) and organic matter content (0.26 to 5.77 g 100 g− 1 organic carbon). Soils showed a …
