Neptune's Harvest Fish Fertilizer


Neptune's Harvest Fish Fertilizer 2-4-1 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 plants 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 20-20-20 fertilizers.
  • Increased marketable yields and improved shelf life on fruits and vegetables.
  • Increase in plants natural sugars resulting in more plentiful, stronger and more colorful flowers and foliage and more fragrant longer lasting blooms.
  • Meets requirements of the National Organic Program (NOP) for use in organic production.
