Level 2 Detail of experimental conditions
Description of study
What?
Penetration resistance and shear strength were measured in three contrasting soils.
When and Where?
The study commenced in 1984 and concluded in 1986. The soil present at site is derived from alluvium. The vegetation on site is classified as a mesophyll vine forest with an understory dominated by the fan palm Licuala ramsayi.
How?
Penetration resistance was measured using a “Bush, Mark I” recording penetrometer fitted with a cone of 12.9 mm diameter, 30o included angle. Shear strength was measured with a “Pilcon” vane, measurements were taken at depths of 5, 10, 15 and 20 cm. Estimates of shear strength and penetration resistance are based on 20 - 25 replicate profiles at each sampling occasion.
