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 site is located on an outwash fan and the soil is formed from metamorphic parent materials. The clay soils show a lack of variation with depth in the upper profile. Vegetation at this site is disturbed and has an understory comprised of fast growing secondary rainforest species penetrated by taller emergents.
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 were based on 20 - 25 replicate profiles at each sampling occasion.
