Can dead fish be used as fertilizer?

Dead fish as fertilizer

Dead fish can be used as fertilizer, but they cannot be used directly. They need to be decomposed and fermented to become organic fertilizer before they can be used. This can make the soil more fertile after use and the plants planted will grow better.

Dead fish can be used as fertilizer for flowers, but they must first be fermented for a period of time. Otherwise, the fermentation and decomposition in the soil will consume a large amount of oxygen, which can easily cause the plants to die of lack of oxygen. The dead fish after fermentation can be used as fertilizer for flowers and is suitable for growing peonies.

How to make fertilizer from dead fish

1. Wash and add brown sugar

The dead fish must first be cleaned to remove the harmful microorganisms it carries, and then brown sugar containing carbon sources and plant microorganisms is added to it, which constitutes the preliminary preparation for fermentation.

2. Fermentation

Next, the processed dead fish should be placed in a sealed container for fermentation. It will take about twenty days to complete the preparation of the fertilizer with stronger fertility.

Key points for using dead fish fertilizer

1. Deep burial

Although dead fish fertilizer will not carry harmful microorganisms after fermentation, it will produce a certain odor and cause damage to the surrounding environment. It needs to be deeply buried for fertilization when used.

2. Add a small amount

Dead fish fertilizer is very fertile and contains a lot of organic ingredients. If the plant does not require a large amount of nutrients, the amount of organic fertilizer applied should be controlled to avoid excessive soil concentration, which will cause water loss in the plant roots.
