Fish fertilizer is one of the oldest natural fertilizers out there. On this week’s podcast, hear how it’s made, and what sets hydrolyzed fish fertilizer apart from fish emulsion. Ann Molloy of Neptune’s Harvest in Gloucester, Massachusetts, tells us how her dad realized waste from the fishing industry that was being thrown away could be made into natural fertilizer.

We also talk about best practices with fish fertilizer, how to apply it and how to get the most out of fish fertilizer. Understanding the manufacturing process explains why fish hydrolysate, which is stabilized with an organically-approved nutrient that plants need, doesn’t smell as bad as fish emulsion, until you mix it with water. Which is why you have to use what you mix with water within a few hours, otherwise it will start to smell like fish again!
