Sydney woke up to this today:
A big dust storm blew through and coated everything in a thin film of
red dust
It's supposed to be fine clay particles from the soil and dry lake beds in the Western Plains.
Anyway it looks -exactly- like the dust you get on LECA balls, it's exactly the same colour, consistency and it's just as difficult to wash off.
The thing is, various scientist types have been telling people that it's packed full of nutrients and will actually be good for gardens!
So this is my question.. if this dust is the same as the dust on Clay Aggregate, why do we wash it out and why don't roots (supposedly) like it?
