Vermicomposting of organic wastes using Eisenia foetida (Savigny)
An experiment was carried out in vermibeds to evaluate the suitability of organic wastes for vermicomposting using Eisenia foetida. The results indicate that nitrogen, phosphorus and potassium were maximum in the vermicompost formed from treatment T12, followed by T3. Calcium and sulphur were observed maximum in T3. T9 registered maximum magnesium content, followed by T8. There was also a ...

Earthworms helping economy, improving ecology and protecting health
Earthworms can treat organic garbage, livestock manure and poultry droppings and turn them into premium organic fertilisers, because humus only exists in earthworm feces and castings, compared with other fertilisers. Earthworms can also supply quality animal protein as feed, and offer the best raw materials for the biochemical and pharmaceutical industries. Vermiculture should be put into a whole ...

Relative efficacy of two methods of vermicomposting for bio-degradation of organic wastes
Two methods of vermicomposting were used for the bio-degradation of organic wastes, viz., the pit method and the heap method. The efficacy of these two methods was compared under field conditions over three seasons (winter, summer and rainy) by using one of the most promising composting worm species, Eisenia fetida. One hundred adult earthworms (Eisenia fetida) were released in each pit and heap. ...

Vermicompost production and its use for crop production in the Philippines
Vermicompost was produced with Perionyx excavatus and Eudrilus eugeniae using animal manures, leguminous leaves, grass and agro-forestry wastes. Yields of corn fertilised with vermicompost at 5t/ha and rice at 2t/ha of vermicompost were comparable with those for corn fertilised with 100% chemical fertilisers and 40% increase over the control for rice. Chinese cabbage and eggplant fertilised with ...

Bio-conversion of organic waste using composting technologies – a review
Composting is nowadays evolving as a highly technical process for processing organic waste separately replacing landfilling along with municipal solid waste. Vegetable waste with high organic content can be composted to produce nutrient rich material that can work as soil conditioner instead of dumping in open landfills. Various studies reveal that due to high organic content of vegetable waste ...

Microbial characterisation of vermicompost and compost of urban waste processed by three earthworm species - Eudrilus eugeniae, Eisenia fetida and Perionyx excavatus
Species diversity of bacteria, fungi and actinomyctes of vermicompost and compost of the organic fraction of municipal solid waste, vegetable market waste and flower waste were assessed using pour plate technique. Of the total 91 entities, 62 were bacteria and 29 were actinomycetes in MW, followed by that of MSW and FW, with 59 and 55 bacterial; 25 and 22 actinomycetes entities, respectively. The ...

Effect of poultry waste on vermicomposting of anaerobically digested cattle dung slurry
This study was conducted to explore the effect of poultry waste (PW) on the vermicomposting of anaerobically digested cattle dung slurry (CDS) using Eisenia fetida worm species. A total of three vermicomposting beds, having different percentage of PW and CDS were established (100% CDS; 75% CDS + 25% PW; 50% CDS + 50% PW). At the end of experiment vermicompost showed a higher concentration of ...
