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 ...

Vermicomposting of flyash: a potential hazardous waste converted into nutritive compost by earthworm (Eudrilus eugeniae)
Vermicomposting of fly-ash(FA) mixed with different proportions of Horse dung (HD) T1 – 100% HD alone, T2 – 10% FA + 90% HD, T3 – 20% FA + 80% HD, T4 – 30% FA + 70% HD, T5 – 40% FA + 60% HD and T6 – 50% FA + 50% HD, using Eudrilus eugeniae was done to evaluate the level of heavy metals (Cr,Cd,Pb and Ni) in the vermicasts and tissue and worm biomass. The better worm biomass and maximum reduction ...

Process parameters analysis for the vermicomposting of shredded paper using Pheretimoid Spp.
This study was to assess the effect of new species of earthworms, Pheretimoid Spp., on vermicomposting and compare the quality of vermicompost against compost produced from the same mix ratio of shredded office paper (SOP) together with grass clippings (GC) and cow manure (CM). Two composting experiments were setup in rotary drum composters namely: 1) composting of SOP, GC and CM followed by ...

Management of water hyacinth (Eichhornia crassipes), an aquatic weed waste, by vermicomposting technology
Water hyacinth has become a menace in Sambhaji tank, Solapur city, Maharashtra, India. An attempt has been made to convert this water hyacinth into a nutrient rich vermicompost using the earthworm Eudrilus eugeniae. The macronutrient and microbial analysis of vermicompost at various intervals of time has been studied and compared with decomposing water hyacinth. It was found that nitrogen, ...

Vermicomposting technology: an efficient biological processing of obnoxious weed water hyacinth (Eichhornia crassipes)
The present work was carried out during the year 2009–2011 to study the physicochemical and microbial analysis of both vermicompost and vermiwash produced from two treatments of water hyacinth: T1: 100% water hyacinth + 5% soil, T2: water hyacinth + cow dung (50% + 50%) by using earthworm species, Eudrilus eugeniae for a period of 90 days. The nutrient values along with microbial count of ...

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 ...

Evaluation of anaerobic digestate as a substrate for vermicomposting
Vermicomposting is an established process to convert organic wastes into vermicastings suitable for plant growth. This research investigated the vermicomposting of anaerobic digestate with four different ratios of sawdust as a bulking material, for 75 days. The optimum proportion of anaerobic digestate to sawdust was identified as 70:30 based on worm growth and reproduction. Vermicomposting ...

Influence of some biological wastes and their combination on growth and reproduction potential of earthworm, Eisenia fetida and their effect on plant growth
Effect on growth and reproduction potential of animal wastes viz., cow, goat, horse and a domestic waste (used tea dust) and their combinations to the earthworm, Eisenia fetida, was studied under laboratory conditions. The effect of above on growth aspects of Bhendi crop was compared with the normal compost individually under green house conditions. The effects on growth were assessed for ten ...

The development of an onsite sanitation system based on vermifiltration: the ‘Tiger Toilet’
This paper describes the development of a novel onsite sanitation system based on vermifiltration, the ‘Tiger Toilet’. Initial laboratory experiments demonstrated that feed distribution was not required, a worm density of 2 kg/m2 could be used, worms preferred wetter environments, and system configuration did not affect effluent quality. Installing the first prototype in the UK proved that ...
