Can sewage sludge be used as fertilizer?

Sludge as fertilizer

Sludge can be used as fertilizer. Sludge composting is the process of continuously degrading and stabilizing the organic matter in it through the action of microorganisms. In this way, the nutritional content in the soil is relatively high. After simple treatment, it can be used as fertilizer.

If sewage sludge is used as flower fertilizer, it is suitable for most plants, such as lotus, water lily, bowl lotus, green radish, lucky bamboo, Christmas cactus and other plants.

How to make fertilizer from sewage sludge

1. Add a certain amount of water to the collected sludge and stir it. It should be boiled water. Then add carbendazim and place it in a dry place. Wait for a few minutes and continue to remove the floating insects.

2. After there are no bugs on the water, pour out the water, then expose the soil to the sun until it is dry, hammer it into powder, and then you can use it as fertilizer.

Key points for using sludge fertilizer

If sludge is to be used to grow plants, it must be treated before use. The treated sludge cannot be poured directly into the flower pot. It is best to mix it with sand so that all the nutrients of the soil can be better utilized to promote the growth of plants.
