Fish extract, also known as fish amino acid, is a nutrient-rich liquid fertilizer that is derived from fish waste. This organic fertilizer is high in nitrogen, phosphorus, and potassium, making it an excellent choice for promoting plant growth and health.
To prepare fish extract, you will need a few simple ingredients and supplies. First, you will need fish scraps or waste, such as fish heads, bones, and guts. These can be obtained from a fish market or seafood restaurant. You will also need a container to ferment the fish scraps, such as a large bucket or container with a lid.
To start, chop up the fish scraps into small pieces and place them in the container. Cover the fish scraps with water, making sure that they are fully submerged. Add a small amount of brown sugar or molasses to the water to help kickstart the fermentation process.
Next, cover the container with a lid or cloth to allow for air circulation. Let the fish scraps ferment for approximately two to four weeks, stirring the mixture occasionally to ensure that it is breaking down properly. The mixture will start to smell foul as it ferments, but do not be alarmed, as this is a normal part of the process.
After the fermentation period is complete, strain the liquid from the solid fish waste using a fine mesh strainer or cheesecloth. The resulting liquid is your fish extract, which can be diluted with water and used as a fertilizer for your plants.
Fish extract is a valuable organic fertilizer that provides plants with essential nutrients to promote healthy growth and development. By following these simple steps, you can easily prepare your own fish extract at home and reap the benefits of this nutrient-rich fertilizer for your garden.
