I haven't posted for a long time, but have been more or less keeping up with fertilizer discussions in "lurking mode".
I have two fertiliser queries which I will post as two separate threads. So this is the first one. Does anyone here know of any preservatives that can be used with liquid concentrate type fertilisers ?
About 18 months ago I made up my own liquid concentrate fertiliser, a sort of modified Klite as 3 separate stocks, one precipitated slowly, one grew bacteria and the third grew fungi. Some years before that I used Dyna-Grow which I remember was remarkably stable compared to some other liquid ferts I tried. So I'm starting from scratch again and was wondering if anyone here had any ideas on this.
The only perservative I know of is sodium benzoate which you need to add at least 0.1% and it only works if the pH is 4 or less. At 1 in 5000 dilution (which is what I'm aiming for) would this be harmful to plants ?
