Mr_Bungle have you ever used fish emulsion for an amendment? Looking for more economic amendments other than nitrogen fixing plants. It needs to be something I can use at scale that doesn’t break the bank. Ordered some emulsion to try... Going to make compost tea out of my mexican sunflower and comfrey as well.
I have used it for my house plant collection not full scale production. Fish emulsion is innately expensive unfortunately. I would suggest using this product and it is currently on sale. You could also try using various blood, bone meal powders or seaweed extract from the same brand below.
The Seaweed extract that they make works really well in larger production settings and has a plethora of micro nutrients that you'll need too. I would highly recommend it. I believe this one uses the coveted Ascophyllum Nodosum specifically.
