Vermicomposting for 140 days by using Lumbricus rubellus was conducted after 21 days of natural pre-composting. Five treatments in different ratio of goat manure: spent mushroom substrate were prepared as feed materials with four replicates for each treatment namely; 20:80 (TA), 40:60 (TB), 50:50 (TC), 60:40 (TD) and 80:20 (TE). As for control, each treatment without earthworm was prepared. On the basis of nutrient elements, goat manure and spent mushroom substrate can be decomposed through both methods of vermicomposting and natural composting. Findings of this study indicated that the higher usage of goat manure with ...

Vermicomposting of sewage sludge (SS) using spent mushroom compost from Pleurotus sajor-caju as feed material was conducted to determine the effect on the concentration of heavy metals, namely Cr, Cd, Pb, Cu, and Zn. Previous studies have reported the feasibility of brandling worms, Eisenia foetida, for vermicomposting SS, whereas we conducted vermicomposting by employing red worms, Lumbricus rubellus, with a combination of different percentages of SS and spent mushroom compost (SMC) for 70 days subsequent to 21 days of precomposting. The vermicompost produced in treatments with a low percentage of SS were fine in texture, dark in colour and odourless ...

Effects Of Vermicomposting Duration To Macronutrient Elements And Heavy Metals Concentrations In Vermicompost, Adi Ainurzaman Jamaludin, Noor Zalina Mahmood Jan 2010

Effects Of Vermicomposting Duration To Macronutrient Elements And Heavy Metals Concentrations In Vermicompost, Adi Ainurzaman Jamaludin, Noor Zalina Mahmood

Adi Ainurzaman Jamaludin

Vermicomposting using Lumbricus rubellus was conducted in two different durations, 10 and 30 weeks in the same plots. Three different of treatments combination were prepared with eight replicates for each treatment namely cow dung : kitchen waste in 30:70 ratio (T1), cow dung : coffee grounds in 30:70 ratio (T2), and cow dung : kitchen waste : coffee grounds in 30:35:35 ratio (T3). Macronutrients elements in the vermicompost from each treatment were measured in the tenth and thirtieth week. Comparatively longer duration of vermicomposting by using Lumbricus rubellus enhanced the quality of vermicompost by the increase of the macronutrient elements ...

Potential Of Spent Mushroom Substrate In Vermicomposting, Adi Ainurzaman Jamaludin, Noor Zalina Mahmood Jan 2009

Potential Of Spent Mushroom Substrate In Vermicomposting, Adi Ainurzaman Jamaludin, Noor Zalina Mahmood

Adi Ainurzaman Jamaludin

The potential of spent mushroom substrate from saw dust in vermicomposting were found out through the growth and reproduction of earthworms including the nutrient elements of vermicompost produced at the end of vermicomposting. Five treatments in different ratio of cow dung : spent mushroom substrate were prepared as feed materials with four replicates for each treatment namely; 80:20 (T1), 60:40 (T2), 50:50 (T3), 40:60 (T4) and 20:80 (T5). After 3 weeks of pre-composting followed by 7 weeks of vermicomposting, T4 showed the highest percentage of growth and reproduction where mean of earthworms’ numbers increases (M = 295 ...


Waste Recycling: Utilization Of Coffee Grounds And Kitchen Waste In Vermicomposting., Adi Ainurzaman Jamaludin, Noor Zalina Mahmood Jan 2009

Waste Recycling: Utilization Of Coffee Grounds And Kitchen Waste In Vermicomposting., Adi Ainurzaman Jamaludin, Noor Zalina Mahmood

Adi Ainurzaman Jamaludin

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 (T1), cow dung : coffee grounds in 30:70 ratio (T2), and cow dung : kitchen waste : coffee grounds in 30:35:35 ratio (T3). The multiplication of earthworms in terms of numbers and weight were measured at the end of vermicomposting. Consequently, only T2 showed significant increase (from it initial stage) compared to other treatments. The presence of coffee grounds in T2 and T3 showed ...

Effect Of Post Composting On Vermicompost Of Spent Mushroom Substrate, Adi Ainurzaman Jamaludin, Noor Zalina Mahmood Nov 2008

Effect Of Post Composting On Vermicompost Of Spent Mushroom Substrate, Adi Ainurzaman Jamaludin, Noor Zalina Mahmood

Adi Ainurzaman Jamaludin

By using Lumbricus rubellus, vermicomposting started after 3 weeks of pre composting. Five treatments in different ratio of cow dung : spent mushroom substrate were prepared as feed materials with four replicates for each treatment namely; 80:20 (T1), 60:40 (T2), 50:50 (T3), 40:60 (T4) and 20:80 (T5). After 7 weeks of vermicomposting, macronutrient elements of vermicompost produced were measured and the process continues with composting when all the earthworms were taken out from the treatments. Macronutrient elements of compost produced were also measured after 20 weeks of composting. The data reveals that 7 weeks for vermicomposting ...


The Consequence Of Vermicomposting Duration To Macronutrient Elements – C, N, P And K In Vermicompost, Adi Ainurzaman Jamaludin, Noor Zalina Mahmood Jan 2008

The Consequence Of Vermicomposting Duration To Macronutrient Elements – C, N, P And K In Vermicompost, Adi Ainurzaman Jamaludin, Noor Zalina Mahmood

Adi Ainurzaman Jamaludin

The effect of vermicomposting duration to macronutrient element in vermicompost was investigated. Three different treatments were prepared with eight replicates for each treatment namely cow dung: kitchen waste in 30:70 ratios (T1), cow dung: coffee grounds in 30:70 ratio (T2), and cow dung: kitchen waste: coffee grounds in 30:35:35 ratios (T3). Vermicompost produced by Lumbricus rubellus were analyzed in week tenth and thirtieth. In conclusion, longer duration of vermicomposting will enhance the quality of vermicompost. This is shown by the percentage increase of macronutrient elements (N & P) and declining of C/N ratio.

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 (T1), cow dung : coffee grounds in 30:70 ratio (T2), and cow dung : kitchen waste : coffee grounds in 30:35:35 ratio (T3). At the end of study, there was a significant difference between numbers of earthworms among the three different treatments (p < 0.05). In contrast with weights of earthworms there was no significant difference (p > 0.05) among the three treatments. By comparing the numbers and weights of earthworms in each treatments (T1, T2 & T3) only ...
