“…In this experiment, the level of phosphorous showed successive increment in both worm treated and control beddings throughout the study period but statistically significant rise was observed in beddings treated with worms (p<0.05) (Tables 1 to 4). In agreement with this finding, Muthukumaravel et al (2008) in vermicomposted vegetable waste, Zularisam et al (2008) in vermicomposted municipal sewage sludge, Ananthakrishnasamy et al (2009) in vermicomposted fly ash, and Chauhan and Joshi (2010) in vermicomposted toxic weeds recorded significant rise in the level of phosphorous. The rise of phosphorous might be due to the action of earthworms' phosphatases and phosphorous solubilizing microorganisms in the worm cast (Blouin et al, 2013).…”

“…Ananthakrishnasamy et al (2009) observed progressive rise of total nitrogen in vermicomposting fly ash with earthworm Lampito mauritii, an indigenous Indian worm. Zularisam et al (2008) observed considerable rise in total nitrogen from 19.6 to 35.7 mg/l within 21 days of vermicomposting municipal sewage sludge. In contrast to the current findings, Atiyeh et al ( 2012) reported 1.8 fold reduction of nitrogen in vermicomposting sludge with earthworm E. fetida.…”

“…Though the total nitrogen content in vermicompost is primarily governed by the initial nitrogen content in the organic waste used as earthworm feed and the suitability of the waste material for the earthworm mediated decomposition (Tognetti, 2007), earthworms play a crucial role in enhancing and improving the nitrogen profile of the waste by addition of mucus, nitrogenous casts, from decaying tissue of dead worms and by facilitating microbial mediated nitrogen mineralization (Suthar, 2007;Zularisam et al, 2008).…”

The major objective of this 90 days vermicomposting work was to evaluate the performance of epigeic earthworms, Dendrobaena veneta, to alter and change four commonly dumped and littered solid wastes in Ethiopian cities and towns into a high quality vermicompost. The experiments were conducted in cylindrical plastic containers with 26 cm depth and 53 cm width under shade. All containers were perforated on the sides for aeration as well as bottom for leachate drainage purpose. The wastes were mixed with cow dung in 3:1 ratio and treated with D. veneta in the following waste and worm mass proportion: 9 kg of vegetable waste treated with 130 g of worms, 9 kg of enset waste treated with 130 g of worms, 5 kg of coffee husk treated with 70 g of worms, 8 kg of khat waste treated with 115 g of worms. Results from all beddings treated by this earthworm species show that total Kjeldhal nitrogen (TKN) increased by 68 to 95%, total potassium (TK) increased between 51 and 76%, total phosphorus (TP) increased between 76 and 100% while total organic carbon (TOC) decreased between 35.3 and 38.5%, the C: N ratio reduced between 62 and 65.5% and considerable reduction was also observed in pH value of the final product. The findings from this experiment indicate that vermicomposting could be one good option to improve solid waste management performance of Ethiopian cities and towns through the production of excellent bio-fertilizer for agronomic purpose.

“…Vermicomposting is the process of synthesis of compost from organic material by the action of earthworms living in the soil with microbial flora [4]. Vermicomposted material containing Perionyx excavatus, Lampito mauritii, Eisenia foetida, Eudrilus eugeniae, can be transformed into environment friendly organic fertilizer containing large amount of nutrients and with the microbial enzyme action on vermicompost increases the easy absorbtion by plant roots [5].…”

Nutrients deficiency is a major threat against Vigna radiata (mung bean) growth. The effects of nutrients can be mitigated by vermicompost, vermi-tea and chemical fertilizers. With the objective to combat the nutrients deficiency, an experiment was conducted in Riverm Kompost Vermikompost Tarım Hay. Mak. San. ve Ltd. Şti. Suleymanpasa, Tekirdag, Turkey under field conditions. In field four different states of fertilizers [F 0 : Control (No fertilizer application); F vc : Solid vermicompost @ 5 ton/ha; F vt : vermi-tea @ 4%; F c : Chemical fertilizers (N&P) @ 80-60 kg/ha] were applied in mung bean. The plants were harvested 45 days after sowing and the evaluation was done on the basis of various morphological (seed germination, root length, shoot length, root fresh weight, shoot fresh weight, root dry weight, shoot dry weight and number of leaves) and physiological parameters [relative water contents (RWC), chlorophyll contents and membrane stability index (MSI)]. The randomized complete block design (RCBD) with three replicates and least significant difference test were used at 5% probability level. The obtained results indicated that significant impact of natural and synthetic fertilizers on morpho-physiological characters of Vigna radiate were recorded as compared to control but foliar application of 4% vermi-tea treatment showed maximum morphological and physiological performance on Vigna radiate.

“…Entretanto, a possível existência de elementos tóxicos não permite que esta técnica seja utilizada universalmente, uma vez que os microrganismos não têm a habilidade (na maioria dos casos) de fixar os elementos tóxicos e torná-los indisponíveis para o meio. Outro processo biológico que pode ser uma alternativa para a desinfecção do LED é a vermicompostagem (Maiola, 2002;Begum & HariKrishna, 2010;Zularisam et al, 2010, Rodríguez-Canché et al, 2010.…”

O objetivo desta pesquisa foi avaliar o potencial agronômico de vermicomposto obtido a partir de lodo de esgoto doméstico e misturas de lodo de esgoto doméstico e solo, segundo os critérios do Ministério da Agricultura, Pecuária e Abastecimento (MAPA), visando ao seu uso sustentável, isto é, transformando um resíduo indesejável em um produto comercial com valor agregado. Os resultados obtidos para os vermicompostos produzidos, se comparados com as exigências de especificações, garantias e limites de contaminantes da resolução n 0 375, mostraram-se satisfatórios para pelo menos uma das misturas de lodo de esgoto doméstico e solo, evidenciando o potencial que este resíduo possui para ser utilizado como fertilizante ou condicionador de solos. Palavras-chave:Condicionador de solo, lodo de esgoto doméstico, vermicompostagem.Evaluation of the agronomic potential of vermicompost produced from domestic sewage sludge ABSTRACTThe main objective of this research was to evaluate the agronomic potential of the vermicompost produced from domestic sewage sludge and mixtures of domestic sewage sludge and soil, following the criteria of the Brazilian Ministry of Agriculture, Livestock and Food Supply (MAPA), aiming at a sustainable use for domestic sewage sludge, transforming an undesirable residue into a valuable commercial product. The results obtained for the so produced vermicomposts, in comparison to the specifications, warranties and contaminating limits requirements of the resolution No. 375, were satisfactory for at least one of the domestic sewage sludge and soil mixtures, proving the potential of this residue for application in agriculture as fertilizer or soil conditioner.
