But as I am sure would have been documented by Evelyn Hutchinson = (The Biogeochemistry of Aluminum, Biological Reviews ~1950) elevated = Al+++ ion activity causes the blue coloration, not elevated H+ activity. = Drawing on memory nearly 30 years faint; H+ and Al+++ ions have a = yin/yang relationship in natural soils. Increasing soil acidity by e.g. = adding elemental Sulphur (on a weight basis 6 times as effective as = Aluminum Sulphate) also leads to an increase in Al+++ activity because = H+ ions displace adsorbed Al+++ from soil colloids. Conversely, adding = Al+++ ions (e.g. as Aluminum Sulphate) increases soil acidity by = displacing adsorbed H+. Yt, Dave Webster.
