If you just want to grow good food and dont HAVE to be certified to
sell, then
you can buy greenhouse grade calcium nitrate fertiliser - you can take this
dry granulated fertiliser and mix in water - hey presto! - liquid calcium -
the stuff made in norway is the best you can get - comes in a 25kg white and
orange bag - and should cost around $12 to $15 per bag - there are a couple
of other European sources that are good - I dont like the Asian stuff and
would not use it - we have already had one instance in OZ of serious heavy
metal contamination in fertiliser from china. If you can't find calcium
nitrate locally - go look where they grow grapes or citrus - our guys run
this material in the dripper lines so I have ready access to it - it is a
very valuable input for our crops, we dont use much, probably only 6 to 8 kg
per hectare per season, in three or four separate treatments.
. If you need certification have a look at calcium lignosulfonate -
this is certifiable organic in our country.
