To start the process we utilize two former surplus products, fish waste and wood waste, in our operation. The fish waste consists of mainly farmed salmon offal from processing plants and farm mortalities from net pens. Concerns about disease in farmed fish are unfounded as fish diseases are harmless to humans. The wood waste consists of sawmill waste (mainly cedar sawdust). These are the ONLY materials used, so there are no non-organics in the finished product. The fish based component provides the protein feedstock and the wood-based component provides the carbohydrate feedstock to stimulate the culture of the microorganisms. The fish waste is placed in a turning drum and mixed until it is minced slurry, the wood waste is then added at a predetermined ratio. This mixture is turned in the drum until it is very homogeneous. To begin the active aeration stage, the mixture is placed in bags and stored in a covered building. Active aeration maintains a constant temperature between 50°C and 60°C during the thermophilic stage for a minimum of five days, killing all pathogens. These bags are “cured” for a period of approximately four to six weeks after the active aeration is removed. Final screening removes any non-conforming material.
COMPOST ADVANTAGES
- This compost can be used without restriction in all applications. It provides a nutrient rich and biologically active root medium that helps plants suppress disease and thrive.
- Fish Compost is a powerful soil improvement including uses such turf/lawn top dressing, mulch, erosion control media, and it helps retain soil moisture.
- Fish Compost is very rich averaging more than 2% total nitrogen.
- Heavy metals have consistently tested very low in our compost. See test results that follows.
- Compost continues to release nutrients into the soil long after initial application.
- It makes an important contribution to a rational management of waste, greatly reducing the use of landfills or incinerators
Our product is a rich source of carbon. Carbon is considered as “black gold” by those in gardening. A soil with rich carbon content will result in a crop that tolerates drought, a crop that grows more vigorously, and a crop that is pest and disease free. Experts suggest that you add carbon by mulching, growing a crop cover, and adding compost.
