Various questions about earthworms, worms for vermicomposting

Dear Mr.ciao Hajo

Thank you very much for your invaluable information about earthworm, I am very interest about this issue and I have some questions:

1) Is there any difference between wild earthworm which found in garden or commercial worm which may be selected in function ,nutrient requirements and reproduction rate?

2) How could differentiated between earthworms and leech (excuse me if it is fun question) ? because sometimes watch earthworms which they have suction organ in their body .

3) About heavy metal removing by earthworm could you please provide me with any reference?
4) In my experiences I believe they also use of fly and mosquito larvae because I put fruit waste in soil and let fly and mosquito settle on this waste after about one week I add couple earth worm to this controlled waste after 48 hour high dense fly and mosquito population were disappeared .
5) what safety and protection must be considered when working on earthworm , any diseses or alergy may be arise fron eartworm or thier byproducts?

Thank you so much

Re: What can we reliably say about pathogen removal with vermifilters?

Dear Mohammad,

I am not the right address for your question, but I will try what I can and hope Dean will jump in where necessary:
  1. surely 'worm' is not equal 'worm', composting worms you find here en.wikipedia.org/wiki/Vermicompost under 'Suitable worm species'.
  2. A leech is not a composting worm and looks quite different, please compare pictures for leech under en.wikipedia.org/wiki/Leech with pictures of compost worms referred to in above article.
  3. The article which I attached to my earlier posting also talks of heavy metal removal. Please refer to that article and its quoted literature.
  4. Interesting observation which adds to the knowledge that vermi-composting is not a single-actor process but that many actors contribute to the aerobic composting process.
  5. I am quite sure that there are not special precautions required, probably less than for touching the FS they live in. But Dean will be in a better position to comment. He has had worms as pets for years ;)

Hope that helps, enjoy the forum,
greetings to Iran,
Hajo

Re: Facts and various questions about earthworms, worms for vermicomposting

Thank you , I also guess they must be of snail species but lacking of shell put me in mistake , Are they consider parasite for agriculture or horticulture ? Are they earthworm killer?

Thanks Mohmmad

Re: Slug,earthworm

Thanks to goeco for his reminding about slug not earthworm , I would like and interested to know slug harms and benefits in sludge in comparison with earthworm it seems slugs are very hardworking cleaner , Could they be useful for hazard removing (physical,biological and chemical solely in hazard sludge not for agriculture or vermicomposting as pre waste treatment?, it seems they have similar nutrient behaviors and similar Earthworm 's digestive system.

Re: Promote VERMIFILTRATION Technology for WASTEWATER PURIFICATION by EARTHWORMS to produce clean water

Dear M M.

Very pleased to know that vermitechnology is sought for wwt process.
Pl. note that worms are highly sensitive species andcrequire their food in well cooked form.
It is to mean that the wwt process proceeds in normal mode, as usually done.

The process to follow is as follows:
Primary - totally anaerobic for 1/3 rd HRT period, and sludges removed regularly for co composting in pits using FS and local bio mass and or cattle dung.
Seconadary- same as above, here in septic tanks can have large, medium and small stones, 1/3rd HRT, sludges for co composting process.
Tertiary- same as above use large open areas for plantation to provide phyto remediation.
Polishing process use for 1/10 th HRT applying extended aeration by subjecting to fountain sprays.
The sludges ex. wwt process are the raw feed. This is to be anarebically processed and say for a week / 10:days then the worms are introduced .

The worms species used in India used to be called Eisonea foetida , these are very hardy suited to trpopic heat and very self generative.

When the FS is consumed and the strength is reducing the worms will move in pits to areas where the matter is newer.
As the digested FS in form of compost is removed, some less active worm population are also removed.
The worms removed are sought after by fish farms, and for hook fishing. Fetches good values too.

Well wishes for apt community practices taking care of SDGs.

Re: is there any particular earthworm species preferred for waste water treatment ?

Dear MM.
You are welcome Sir.
Pl feel free to offer your details on your experience.
1. Both water and wastes to be used by communities.
2. Re use water can be used for growing fodder like elephant grass Etc.
3. This is usedcas feed for cattle for milk, poultry for eggs and meat. goats, Etc..
4. All tests for water. and other produces done and monitor - controlled.
5. Wastes realise compost - manure and extra worms too! Used for fishing!
6. When these facilities are gainfully used, communities have a good QoL.
And the wwt plants are sustained well
7. Have a good aesthetic floral gardens around the wwt plants and
8. Pay attention to maintainance practices of cleaning pruning and up grades.
Well wishes to communities.
