How to Raise Earthworms with Fresh Cow Manure? Detailed Technical Points

   Fresh cow manure can be used directly to raise earthworms without fermentation. If rotten melons, fruits, rotten vegetable leaves and the like are mixed with the cow manure, the effect of raising earthworms will be even better.

    First, pile the cow manure into a manure heap 2 m long, 1 m wide and 35 cm high (thick). Every day, use an iron rake to loosen the topmost cow manure. The thickness of cow manure that needs to be loosened and dried to about 50% dryness is about 5—8 cm; when it is about 50% dry, the earthworm seeds can be put in. Each manure heap can hold 30,000 egg-laying breeder earthworms. Collect the worm castings and cocoons once every 10 days, and start another heap for incubation. Collecting the cocoons once every 10 days and incubating them separately can ensure that each batch of earthworms is uniform in size and specification. During the raising period, if the worm castings are found to be dry, spray em water promptly, mixed with clean water or rice-washing water or the rice soup from cooking rice at a ratio of 1:5, then spray. Generally, spray once every 3—5 days. Earthworms raised by the above method grow quickly, and the cocoons produced are numerous and large. Note that poultry and livestock manure must be fermented with em or dried in the sun and then mixed to a moisture content of about 60% before it can be used to raise earthworms.
