Thanks for that information Jeff.
I am picking up 20 litres of liquid sea minerals today from Pacific Salt in
Melbourne, Australia. The sea minerals are what is left after they have
extracted the sodium (to sell as table salt) so the salt content is not an
issue - it is $44 for 20 litres which is a LOT cheaper than the bull kelp
alternative of Seasol and I would imagine has more minerals... will check
the analysis when I get it (I know I should have done it already....)
The reason table salt is SO bad for you is because they have taken all the
minerals out of it and sold them off to other buyers, chemical companies etc
- Celtic or other natural sea salts retain these minerals.

THis does sound promising, much more so than mining 'rock dust'
However, a word of caution, while seawater contains the whole gamut of
micronutrients, it also contains an excess of sodium (Na+) and
Addition to soil could lead to sodic or saline soils (no soil
structure, poor drainage). I would advise that sea solids not be used
in 'at risk' sites.
Any soil that qualifies as "clay" or any climate that requires
irrigation for normal row crops.
Clay soil would hold onto the salts, and because of the poor
infiltration would not flush them from the soil.
The drier climates are subject to saline build up due to inadequate
depth penetration of water. (Drip irrigation is somewhat resistant to
Finally I would like to note that certain crops can use sodium in the
place of some potassium (K in fertilizer), other seem to require small
amounts to grow properly.
Muskmelon (sometimes called Cantelope in the USA) and Sugarbeets
all show improved growth in the presence of sodium. Including this
crops in a rotation could mitigate these effects.
