Experiments were conducted to remove heavy metals (Cr, Cd, Pb, Cu and Zn) from urban sewage sludge (SS) amended with spent mushroom compost (SMC) using worms, Lumbricus rubellus, for 105 days, after 21 days of pre-composting. Five combinations of SS/SMC treatments were prepared in triplicate along with a control for each treatment in microcosms. Analysis of the earthworms' multiplication and gr...

Scientific investigations have established the viability of using earthworms as a treatment technique for numerous waste streams besides producing organic fertilizers. Vermicomposting results in the bioconversion of the waste stream into two useful products, earthworm biomass and vermicompost. The former can be used as a protein source whereas vermicompost is considered as an excellent product ...

ABSTRACT: Vermicompost was prepared from leaf materials such as Gliricidia sepium Jacq, Leucaena leucocephala (Lam.) De Wit and Cassia auriculata Linn and earthworms, Eudrilus eugeniae (Kinberg) and Eisenia fetida (Savigny) along with cowdung in six Treatments. Fortnightly analyses (0, 15, 30, 45 and 60 d) of the colony forming units (CFU) of bacteria in vermicomposts, vermicasts and earthworm ...

Abstract Vermicompost is an organic fertilizer resulting from the decomposition of materials by utilizing earthworms. The presence these microorganisms means that vermicompost contains compounds are needed to increase soil fertility or for plant growth. This study aims analyze nutrients bio-vermicompost with a combination application techniques beneficial microbes and used factorial Completely ...

Soil applications with poultry refuse, cocodust, vermicompost, ash, sawdust, khudepana, cowdung, solarized sand, Trichoderma harzianum and or with seed treatment by T. harzianum were evaluated against damping off disease complex of potato and chilli. All the treatments significantly reduced percent damping off over control. T. harzianum treated seed along with soil treatment with T. harzianum p...

Vermicomposting using Lumbricus rubellus for 49 days was conducted after 21 days of pre-composting. Three different combination of treatments were prepared with eight replicates for each treatment namely cow dung: kitchen waste in 30:70 ratio (T(1)), cow dung: coffee grounds in 30:70 ratio (T(2)), and cow dung: kitchen waste: coffee grounds in 30:35:35 ratio (T(3)). The multiplication of earthw...

It is known that in vermicomposting soil layer in bedding of the reactor helps in earthworm biomass growth and reproduction but growth is influenced by soil characteristics such as texture, pH, and water holding capacity. The present study was conducted to asses the influence of soils on earthworm biomass growth and reproduction during the vermicomposting of source separated human faeces. The s...

Field experiment was conducted during 2003-04 to study the effect of vermicompost, farmyard manure and water hyacinth compost in comparison to chemically fertilized and unfertilized plots on crop-plants in HYV Swarna and local variety Magaisal. The experiment followed split plot design with two varieties of rice in the main plots and fi ve nutrient sources randomized in sub plots. Signifi cant ...

BACKGROUND: Management of water deficit is a great factor to sustainable crop production, especially in arid and semi-arid regions. Vermicompost is an organic compound that is microbial active and rich in nutrients that results from the interaction of earthworms and microorganisms with organic matter decomposition. OBJECTIVES: This research was carried out to ...

The surface mining activities in the past and in recent times has resulted into existence of number of overburden dumps through excavation and depositing removed soil and rock debris. These dumps require environmental stabilization/restoration, through proper revegetation. To achieve this aim, a study was conducted to find the efficacy of Mung bean (Vigna radiata L.), an economically important ...
