Please contact us to discuss a set of analyses customised to meet your needs.

Particle Size Analysis (Sand/Silt/Clay, Stones)
Solid/Void Ratio Determinations (Dry Bulk Density, Particle Density, Total Porosity, Macro Porosity)
Water Release Characterisation (Available Water Capacities, Field capacity, Air Capacity, Wilting Point)
Volumetric water contents at a range of applied matric tensions (0–1500 kPa) i.e. pF curves
Hydraulic Conductivities (Saturated and/or unsaturated hydraulic conductivity at a variety of matric tensions (e.g. K_–20, K_–40, K_–100)
Soil Engineering Measurements (liquid and plastic limits, miniature compaction tests*)
Other Analyses (Potting Media analyses, Greenroof and raingarden substrate analyses*, Water–stability of soil aggregates*, Aggregate Size*, Air Permeability*)

Field Determinations (infiltration rates, hydraulic conductivities#, cone penetration resistance*, oxygen diffusion rates*, plant root distribution*)
Sample Collection (bulk sampling, undisturbed core sampling, drill core sampling to 5 m)
