you know sage, i'm planning to do blueberries in raised beds. the ones
in the ground are pitiful after 10 years. i could never seem to get
enough fertilizer on them.
they say that real alkalinity is hard to ovecome. in droughty places,
there's never enough rain to wash away sodium buildup. each watering
only adds more. have you tried sulfur? it's the only thing that works
for my farmer/nephew in Yuma. the sodium is still there, but at least
it's neutralized to form sulfites and sulfates.
i assumed that peat moss was already as leached as can be, so i have an
alternate theory. organic acids basically just have a carboxyl group
(-COOH) attached to them, like vinegar (CH3COOH). but as molecules
become larger, they're less likely to be soluble. so why not huge
organic molecules left over from anaerobic decomposition of cellulose,
with lots of -COOH groups attached? now the mechanism would not be
leaching out acid, but sucking up metallic ions like Ca++ and Na+. this
seems reasonable to me, a total chem novice, but i'm just guessing.
