As far as getting a well-known college to do an objective study associated with Neptunes Harvest's products, a sincerely believe that will never happen. I used the terms 'enzymes' and 'growth hormones' because those were some of the terms Neptunes Harvest used in their brochure definitions along with what additional micronutrients are found in their fish/seaweed combination. As far as cost goes, remember Neptunes Harvest uses a hydroslate process (cold process) to extract the ingredients from the fish renderings rather than boil the fish, like fish emulsion, which destroys all of the enzymes and growth hormones. As far as strawberries go, we have not tried to use it as a foliar spray, but I don't see any issues with using it. However, since the major nutrient value is only 2-3-1, we only recommend it as a supplement to your ground fertilizer applications. We are very pleased with the results and would recommend using it to anyone. The reason we spray is to give the plants an extra dose of micronutrients as well as enzymes and growth hormones during their bloom and fruit ripening process they may not get otherwise if (1) the soil pH is not where it should be, especially when it comes to the iron needs of blueberry plants, or (2) adequate levels of other micronutrients/enzymes/growth hormones are not present in the soil at all.

We use granular fertilizer when the plants first start to wake up in late February, then spray with the 'fish juice' every 10 days once their leaves start to come out until the berries start to turn colors. We've used Neptunes Harvest fish/seaweed extract for 3 years now on our 4 acres of blueberries and blackberries and we are quite pleased with the results.
