Vermicomposting influences phosphorus microbiology leading to phosphorus enrichment in end product
The investigation reveals the relative efficacy of composting techniques regarding phosphorus transformation of rice straw (RS) and water-hyacinth (WH). The recipe for each substrate: cow-dung:soil:FYM was in the ratio of 6:3:0.5:0.5. Vermicomposting of WH resulted in the highest proliferation of phosphate solubilising microorganisms (PSM) and their solubilising capacity (PSC) besides causing the ...

Potential of Eisenia fetida for vermicomposting of garden trimmings spiked with cow dung
The garden residues and trimmings were vermicomposted in order to mitigate environmental problems caused by them. The results of experiments indicated that the addition of Garden Trimmings (GT) up to 30% with cow dung (CD) produced good quality vermicompost in terms of increased NPK status as well as decrease in C : N and C : P ratio. A comparison of the decomposition of GT + CD in ...

A comparative study between composting and vermicomposting for recycling food wastes
The main objective of the present work was to evaluate the potential of the epigeic earthworms Eisenia fetida and Eudrilus eugenaie regarding the decomposition of food wastes. The effectiveness of composting and vermicomposting for the treatment of food wastes was judged by analysing a wide range of physic–chemical parameters. The results from the compost process monitoring showed porosity rise ...

Vermiculture for sustainable horticulture agronomic impact studies of earthworms, cow dung compost and vermicompost vis-a-vis chemical fertilisers on growth and yield of lady's finger (Abelmoschus esculentus)
Pot experiment was conducted to assess the performance of live earthworms and vermicompost on growth and yield of lady's finger (Abelmoschus esculentus). Among the various treatments, live earthworm + cattle dung (as feed), cow dung compost, vermicompost, chemical fertiliser and control were organised. The results indicated that all growth and yield parameters were found superior and ...

Amelioration of the physical properties of slate processing fines using grape marc compost and vermicompost
The effect of grape marc compost and grape marc vermicompost on the soil physical characteristics of slate processing fines, a waste produced during the processing of slate blocks, has been evaluated in two short-term studies. In the first study, the slate processing fines were mixed with the composts at three rates (4, 8, and 16% dry weight, equivalent to approximately 60, 120, and 240 Mg ha–1), ...

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. ...

Remediation of heavy metals from urban waste by vermicomposting using earthworms: Eudrilus eugeniae, Eisenia fetida and Perionyx excavatus
This study revealed that three earthworm species, viz., Eudrilus eugeniae, Eisenia fetida and Perionyx excavatus, through vermicomposting remediated heavy metals - Pb, Zn, Cd, Cu and Mn from the urban waste - organic fraction of Municipal Solid Waste [M(O)SW], vegetable Market Waste (MW) and Floral Waste (FW). The concentrations of Zn, Cd and Cu were 36.1, 50.9 and 70.2% higher in M(O)SW compared ...

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 ...

Integrated composting and vermicomposting: a boon to industry for waste clearance
The industrial bio-solid waste management is a global problem which has become even more challenging due to rise in population, industrialisation as well as changes in standard of living. Different waste management options, particularly landfill and incineration have potential adverse effects on environment, health, soil and biodiversity. There are little potential problems of environmental ...

The wonder of red wiggler worms
Worms are going to play an ever-increasing role in waste management and soil production. Red wiggler worms convert food scraps and paper into nature's finest fertilizer. As nature's original recyclers, they consume approximately half their weight daily!Many municipalities have introduced organic collection programs, and backyard composting is widespread. Vermicomposting is a great alternative for ...

Improved performance of red worms (Eisenia andrei) in compost of cattle manure rinsed with water
To achieve satisfactory results with vermiculture, it is important to know how many times to rinse cattle manure to eliminate salts. Treatments under evaluation were 0, 1, 2, 3, 4, 5, 6 or 7 rinses in a tap water: manure ratio of 1 : 1 (v/v). Electrical Conductivity (EC), Biomass of Worms (BW) and Number of Cocoons (NC) were evaluated. The EC ranged from 2.57 to 0.5 dS·m−1 for T0 and T4. ...

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 ...
