I got a hankering to make my own fish emulsion fertilizer, there is mention of doing it on the web. I can't find fish emulsion being sold here....odd for such a fishy country. Home made is supposedly better too. The markets all gave me the cold shoulder about getting guts and unsold fish, said some service takes it all away, so I went to a fish restaurant in town, and the owner was happy to oblige, saved a big plastic bag full for me. You have to rot it in a closed container, and add some greens to help absorb the smell......still, it is about the most mf terrible smell after a few days that you will ever experience in your life, like an entire city dump contained within a five gallon bucket. Just opening the can to stir it after a day or two takes some courage, and better to do it mid between the hours of eating anything. Keep the flies out, I found a few maggots in there too. After about two weeks, the smell pretty much goes away, the bacteria has worked it over pretty good. If you could grind it up before starting the decomposing process, it would be better and probably faster, I only chopped it up into little pieces, except for one big fin that I just tossed in. I added water to the can, enough to cover the mix, and the mush turns to a heavy brown liquified gravy. Being concentrated, you have to dilute it for both aerial spraying and watering at the base. it isn't entirely completed, still a few more days to go, still el stinko, but I have made a couple applications with the stuff to test it out, and I can really tell that the plants go apeshit over it, get a lovely color and it's like they suddenly are reaching to the sky to praise God or something. I only recommend it if you have a strong stomach! I feel kind of sick here just thinking about it.
