Fish emulsion doesn't have the same biological value as fish hydrolysate (unpasteurized liquid fish stabilized with phosphoric acid) so I can' t speak to its use. Fish emulsion does have a slightly higher nitrogen content than true liquid fish. But it lacks the unsaturated fats that make fish with its oils still intact far more enriching. I use a foliar rate of 2 gallons per 100 per acre and a ground rate of 4 gallons per 100 per acre with fish hydrolysate. Some of our purposes are the same, Leigh, but I'm focused even more so on fungal support. The price one pays for fish has much to do with the rates chosen. I purchase by the 55-gallon drum direct from the
national distributor for Organic Gem which is far more economical than by the single gallon, especially if from a retail organic supplier.
