Bulk Fish Fertilizer for Commercial Farms & Greenhouses
Scale your soil health and lower your application rates with professional-grade organic fertility. Made fresh on the docks of Gloucester, MA, our cold-processed hydrolyzed fish fertilizers are available in high-volume formats—from 55-gallon drums to tanker truck deliveries—to meet the demands of large-scale agriculture.
Why Commercial Growers Choose Hydrolyzed Fish over Emulsions
We know that in commercial agriculture, efficiency is everything. We are not a standard fish emulsion. Our cold-process method preserves natural oils, proteins, and enzymes that are normally boiled away in standard emulsions. For your farm, this means three measurable advantages:
Lower Application Rates
Because we do not remove the natural oils and proteins, nutrients remain in the soil longer. Our growers consistently find that lower N-P-K rates of our hydrolysate can meet or exceed the crop yield results of higher-rate chemical programs.
Zero Equipment Clogging
Forget the thick sediment that ruins irrigation lines. Our rigorous multi-step screening process ensures our liquid fertilizers flow seamlessly through drip tape, boom sprayers, and fine-mist foliar systems.
Better Working Conditions
Because we process fresh-caught fish same-day at the dock, the putrid odors of decomposition are avoided. The mild scent dissipates quickly, improving conditions for your farm workers.
