Acid-binding capacity-4 (ABC-4) was determined by the amount of 0.1 N HCl required to lower the initial pH of a sample to a stable pH of 4.00 ± 0.04 (Lawlor et al., 2005). Each sample was analyzed three times and value reported is average of sample means ± standard deviation of sample means.
Number of samples analyzed, with each sample analyzed in triplicate.
