Can fish scales be used as fertilizer?

Fish scales as fertilizer

Fish scales can be used as fertilizer, but do not bury them directly in the soil. This will easily cause pests to breed in the soil and will compete with the plants for oxygen during the fermentation process. Correct use of fertilizers will make poor soil fertile and plants grow more vigorously.

Fish scales can be used as flower fertilizer, but they must first be composted. After the fish scales are fermented, a large amount of protein and organic matter in them are stimulated to become a good fertilizer for flowers. It is generally suitable for growing peonies and roses that like fertile soil.

How to make fertilizer from fish scales

1. Cleaning and collection

Fish scales may be stained with microorganisms, insect eggs and other things, so they should be cleaned before use to reduce possible harm, and then collected and put away for use.

2. Composting and fermentation

Then put the cleaned fish scales into a sealed container, add appropriate amount of water, move it to the sun, and let it stand for about a month, and you can get good organic fertilizer.

Key points for using fish scale fertilizer

1. Deep burial use

Because fish scale fertilizer goes through a process of composting and fermentation, it will produce some sour and smelly odors. If it is applied exposed, it will easily damage the surrounding environment. It is best to bury the fertilizer deeply.

2. Add appropriate amount

The fertility of fish scale fertilizer is very sufficient, but it must not be applied too much, otherwise the soil will have an excess of nutrients, resulting in the plant roots being unable to absorb water, and eventually the plant will wither and die.
