Can expired flour be used as fertilizer? Steps to ferment expired flour into fertilizer

Although expired flour can be used as fertilizer, the nutrients in it are relatively few. It is better to send it to the farm as feed and then convert it into fertilizer after the animals excrete it.

Expired flour can be used as fertilizer. Only ammonium nitrogen and a small amount of trace elements can form fertilizer. However, please note that it will only be effective after fermentation. In addition, a large amount of carbon dioxide will be formed after the flour is fermented, and the fertilizer efficiency is not high.

Expired flour fertilizer production

Pour the expired flour into a container, then add ten times the volume of water, stir evenly and let it ferment naturally. Generally, the fermentation will be completed in about 30 days. At this time, you can directly spray it on the plants. It is a very good organic fertilizer.

Use of expired flour fertilizer

1. As flower fertilizer

Pour the flour back into the container, then add ten times the volume of water. After fermentation, take the clear liquid on the top, dilute it with water and then spray it directly on the plants. It is rich in various nutrients needed for plant growth, but the frequency of use should not be too high.

2. Do not mix soil

Expired flour should not be mixed into the soil as fertilizer, because watering it later may make the soil sticky, thus affecting the breathing of the plant roots.
