| Bulk Density - Defined as the mass of dry soil per unit bulk volume (g/cm3). Bulk density determined by measuring the oven-dried mass (105°C) of undisturbed cores.

| Soil pH (water) - A measure of the logarithm of the reciprocal of hydrogen-ion concentration, it gives a measure on a scale from 0 to 14 of the acidity or alkalinity of the soil. Soil samples are air-dried, sieved (<2 mm) and shaken in water (1:5 soil : extract) for 1 h. Samples are centrifuged (10 min at a relative centrifugal force of 850 G) before measuring pH with a glass electrode. Reference: Rayment, G.E and Higginson, F.R. (1992). ‘Australian Laboratory Handbook of Soil and Water Chemical Methods’. (Inkata Press, Australia.) |
