About Neptune's Harvest Fish Fertilizer

Neptune's Harvest fish hydrolysate is an all organic, highly nutritional protein fertilizer, made utilizing naturally occurring enzymes present in fresh North Atlantic fish. We produce this using a cold process employing enzymes (natural biological catalysts) which break down fish, or fish frames (the part left after the fillet is removed for human consumption) to simpler protein complexes. This process is called Hydrolysis.



No synthetic materials are mixed into the fish hydrolysate, and the only manipulation the product undergoes is grinding and hydrolysis. This process yields a stable, non-odorous, liquid fertilizer that is an easy to use, safe product. The nitrogen in Neptune's Harvest fish fertilizer is derived from fish protein in the form of amino acids which when added to the soil, slowly break down into basic nitrogen compounds. While a percentage of nitrogen becomes soluble due to the nature of the manufacturing process, no inorganic nitrogen has been added.



In the past, there have been advantages in using manufactured chemical fertilizers, however as we now realize, this has been at the expense of the environment and depletion of many soil elements. The continued application of only concentrated chemicals on the soil have reduced much of the biological life that contributes to the efficient utilization of many plant nutrients.



Neptune's Harvest hydrolyzed fish does no biological damage to the soil and will promote the growth of beneficial bacteria making the soil less compact and better able to drain, yet hold moisture better for future plant use as it is needed. With our cold process, the vitamins, amino acids, enzymes, and growth hormones are not damaged or destroyed. Because no oils or proteins are removed, the nutrients remain in the soil longer, and lower N-P-K rates can be used to meet or exceed the results obtained by chemicals with much higher rates. Some advantages to using hydrolyzed fish fertilizer are that it rebuilds soil, gives excellent plant growth with increased yields, and is made from a renewable aquatic resource. Our hydrolysate fertilizer is filtered through an 165 mesh screen as a first step, and then through a 150 micron screen before it is packaged. This ensures an ease of application with most irrigation sprayer systems that is second to none.



Beware of imitations. Neptune's Harvest is the leading manufacturer of fish hydrolysate fertilizers in the United States with extensive sales in the U.S. and throughout the world.
