Over the christmas I was introduced to a concept in gardening called korean natural farming. This is pioneering in soil regeneration.
I have just began experimenting by making Fermented plant juice or FPJ which is basically just one part plant matter to one part brown sugar.
Pit them in a jar with breathable lid for one week, strain and dilute about ratio 500 to one.
If you want nitrogen feed make your FPJ from green new growth. Want carbon use brown etc
I will update how this experiment goes!!
