Sea-Change KFF™ Liquid Kelp & Fish Hydrolysate

Fish hydrolysate is prepared from fresh residues of several species of fish put into water and ground up finely. The fish is broken down by natural enzymes and then stabilised. Fish emulsion is prepared by cooking, which means that it can be made from fish and fish parts that are several days old. During the cooking process, oil is removed and used for other purposes. 

Cooking the fish emulsion results in a net loss of some of the components (along with the oil that is removed). This means that fish emulsion is not as nutrient-rich and effective as hydrolysed fish, making fish hydrolysate a more complete fertiliser than fish emulsion.

Hydrolysed fish is also available in liquid form, whereas fish emulsion has a thick consistency.

Fertilisers containing fish hydrolysate contain nutrients that must first be digested by organisms in the oil (such as bacteria, earthworms and fungi) before they become available for plant roots to use. This microbial activity increases the amount of organic matter in the soil and thus enhances the strength and vigour of plants. Fungi and bacteria in the soil break down nutrients to make them available to plant roots. They also loosen the soil as they go about their business, leaving soil aerated and allowing plant roots to grow faster and stronger. 

Along with improving soil health, fish hydrolysate also increases soil fertility by providing the essential nutrients necessary for plants to thrive. These nutrients encourage help to improve plant brix levels, growing plants that can better withstand diseases and pests.
