Can silt be used as fertilizer? How to make organic fertilizer from river silt?

Silt is a common organic fertilizer that is formed by years of accumulation. Although it has a relatively high organic matter content, it may also contain a lot of animal feces, debris, etc., and there will be more bacteria.

Silt can be used as fertilizer because it is rich in organic matter and can be continuously degraded by microorganisms. Its nutritional content is relatively high and it can be used after corresponding treatment.

Sludge fertilizer production

Mix sludge, sawdust, pulverized coal, etc. in proportion, then sprinkle the bacterial solution on it and mix the materials thoroughly. After the bacterial solution and materials are fully in contact, pile them up to about 1.5 meters for fermentation.

Use of sludge fertilizer

1. Base fertilizer

If silt is to be used to grow flowers, the treated silt needs to be mixed with sand and then used to plant plants. This will better utilize the nutrients in the soil and promote the growth of plants.

2. Planting vegetables

Add sawdust, animal manure, river sand and other materials to the treated sludge in a specific ratio of 4:2:2:2. After it is fully decomposed, it can be used as organic fertilizer. It can supplement nutrition for vegetables without burning the roots.
