A natural organic fertilizer solution! Neptune's Harvest Hydrolyzed Fish Fertilizer is an organic fertilizer made from fresh North Atlantic fish. It is made by a unique cold process that protects the vitamins, amino acids, enzymes and growth hormones. It also contains all the micro and macro nutrients naturally found in fish. The nitrogen and other nutrients are chelated, so they are readily available for the plant's consumption. Unlike fish emulsions, Neptune's Harvest retains the fish proteins and oils and has no unpleasant odor. University studies have shown Neptune's Harvest to outperform chemical fertilizers. Has a guaranteed analysis of 2 - 4 - 1. OMRI listed for organic use. 1 quart bottle makes 32 gallons.
