Hey should I buy some Fish Emulsion while I'm there. Never used it but was going to make some soon as I get a ride to go fishing.
Now your speaking my language! Store bought emulsion is OK at best. It works but if you really want to see superior results go with hydrolysate.
The main difference between fish hydrolysate and fish emulsion is the manufacturing process:
Fish hydrolysate
Made through a cold-pressed liquefaction process, fish hydrolysate retains the fish's oils and proteins. It's a rich source of nutrients for soil microbes and fungi, and can be used as a soil fertilizer, added to compost piles, or used in worm farms.
Fish emulsion
Made by heating fish to break down solids and remove oils and proteins, fish emulsion is thick and has a consistency similar to molasses. It can be difficult to handle and may clog sprayers or get stuck in holding tanks.
Other differences between fish hydrolysate and fish emulsion include:
Production costs: Fish hydrolysate has lower production costs than fish emulsion.
Aroma: Fish hydrolysate doesn't have an unpleasant aroma.
Chemicals: Fish hydrolysate isn't made with harsh chemicals.
If your feeling ambitious and want to make your own, you'll need to first make LAB serum. (Lactic Acid Bacteria) Now i won't go into the process or steps because it's easily found with a simple YouTube search, but it sounds like you may have a compost tumbler or pile. If so, I'd recommend you compost the curd that's generally discarded from the culturing process of making LAB serum. That's alot of protein right there, and proteins are huge in organics, especially when they're enzymatic digested, such as with fermentation.
Once you have the serum made, the options are almost unlimited what you can do with it. I mainly use it for making fermented extracts, immediately bio-available foliar or drench. Waste not, want not.... good luck!
