pH CaCl2 (0-5cm) Lime -
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 were air-dried, sieved (<2 mm) and shaken in 0.01 M CaCl2 (1:5 soil : extract) for 1 h. Samples were 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).
