How to ferment cow dung to raise earthworms?

1. Feed preparation:

Fermentation: Use rice straw or stalks to spread a 10-15 cm thick layer of dry material, and then spread 4-6 cm of manure on the dry material and repeat 3-5 layers. Use a spray bottle to spray water on each layer until the water seeps out. If garbage is used, pile up one layer of garbage and one layer of manure.

There is no limit to the length and width, and it should be covered tightly with a film. In the season with higher temperatures, it should be turned over every 7 days. Generally, the fermentation of the feed is completed after 3-5 times of turning over.

After the feed is fermented, test the pH value. Earthworm feed generally requires an appropriate pH value of 6-7.5, but the pH value of many animal and plant wastes is often higher or lower than this value.

When the pH exceeds 9, acetic acid, salt or citric acid can be used as buffers; scientific feed ratio is the most effective way to increase the yield of farmed earthworms.

2. The above recipe examples require:

① 50% cow dung, 50% pulp sludge;

② 100% cow dung or 100% mixture of all livestock dung;

③ 20% each of cow dung, pig dung, and chicken dung, and 40% of rice straw;

(Note: Chicken manure needs to be used to raise maggots or left for more than 1 year before it can be used to raise earthworms, otherwise the earthworms will all escape or die.)
