This study examines the potential of tiger worms (Eisenia fetida) in vermiculturing Municipal Sewage Sludge (MSS) into beneficial vermicompost or biofertiliser. Weight of vermicast: The net weight of harvested vermicast was found to be merely equivalent with the sewage sludge fed to the worms. The humification parameter, the % CHS , slightly increase during the composting phase (90 days), and through the vermicomposting period the CHS content is about 50% greater than in composted material (CRM).
The HA-like fraction isolated throughout the process (composting followed by vermicomposting) presents C and O content similar to those HA extracted from cattle manures before and after vermicomposting by Plaza et al. We gardeners are designers, nurturers, and defenders of little island ecosystems — gardens — that are totally different than our surrounding native biomes.
Plants need pretty much the same things that we need for vibrant health: a wide range of available nutrients, the right combination of oxygen and carbon dioxide, sunlight, a diversity of microbes, and a comfy place to put down roots. Worm castings, aka worm compost or worm poop, are to the plant what probiotics are to our gut. Here’s a cartoon of the whole vermicomposting process using a small, indoor bin – but you can also do it outside in a pile. I’ve spent close to 10 hours in the past two days with a film crew who is making a short film about Biosphere 2. One of my dreams is a re-purposing of all of those weinermobiles out there to become wormmobiles to SPREAD THE WORM!
Decomposable organic wastes such as animal excreta, kitchen waste, farm residues and forest litter are commonly used as composting materials. The types of vermicomposting depend upon the amount of producton and composting structures. Small-scale vermicomposting is done to meet the personal requirement and Farmer can harvest 5-10 tonnes of vermicompost annually.
While, large-scale vermicomposting is done at commercial scale by recycling large quantity of organic waste with the production of more than 50-100 tonnes annually. Vermicromposting is done by various methods, among them bed and pit methods are more common.
Cow dung and chopped dried leafy materials are mixed in the proportion of 3: 1 and are kept for partial decomposition for 15 – 20 days.
The level of nutrients in compost depends upon the source of the raw material and the species of earthworm. It is economically viable and environmentally safe nutrient supplement for organic food      production. Tiger worms weighed 1000 g were cultured in plastic bin (45x30x30 cm) containing 25000 g sewage sludge taken from a selected sewage treatment plant in Malaysia.
As shown in Table 3, almost 93% sewage sludge has been converted into vermicast during the 21 days of vermicomposting.
The solid lines were calculated on the basis of the sixth polynomial equation (with R2 values exceeding 0.999 in all cases). We humans get our nutrients from our food and supplements; plants get theirs from the soil and soil amendments. The microbial richness of castings are critical to the cycling of nutrients in the soil for use by the plants, much as our gut bacteria help us use the vitamins and minerals in our food. I have a couple ‘wormshops’ coming up in April in the Tucson area – just check my website for details. I was interviewed about the experiences that I had building the closed ecological system, and about living inside for two years in the early ’90s.
Here’s to our collective vibrancy, the health of the planet and the positive impact that we can all have with directed effort!
Elaine Ingham, discussing the soil, the soil food web, and plant growth, plus a bit about the collapse of civilization through poor agricultural practices. It is one of the easiest methods to recycle agricultural wastes and to produce quality compost.
In general, animal dung mostly cow dung and dried chopped crop residues are the key raw materials. Eisenia foetida (Red earthworm), Eudrilus eugeniae (night crawler), Perionyx excavatus etc.
The compost shout be kept over a heap of partially decomposed cow dung so that earthworms could migrate to cow dung from compost (fig.7). It’s spring again, time to get the soil ready to be the anchor and the nourishment to the seedlings I’ve grown that are ready to set out. Add a little mineral-rich rock dust and you’re on the road to a great organic garden that will yield vitamin- and mineral-rich produce. My experiences with the living systems in Biosphere 2 caused a paradigm shift in my thinking about gardening. Mixture of leguminous and non-leguminous crop residues enriches the quality of vermicompost.
Red earthworm is preferred because of its high multiplication rate and thereby converts the organic matter into vermicompost within 45-50 days. Nutrients in vermicompost are in readily available form and are released within a month of application. That means, for 1000 g earthworms eat almost about 1000 g feeding material to the bin each day.
Comparative evaluation of microbial and chemical leaching processes for heavy metal removal from dewatered metal plating sludge. Here in Oracle, AZ, I’m pretty confident that freezing nights have passed and that by the end of April, soils will be warm enough for great hot-season plant growth.
Also, many communities have their very own vermiculturists (worm growers) who can provide worms, instruction on composting with worms, and castings. I had become a gardener of the atmosphere as much as a gardener for food, finally viewing myself and my actions as a part of the whole earth system.



This behaviour reflects, probably, a reduction of aromatic structures, suggesting that in the final product of this vermicomposting process the organic compounds are more degradable, probably with a greater content of aliphatic structures than in the compost end-product.
Tomatoes, chilis, beans, eggplants, squash, melons, Malabar, and Egyptian spinach plus a palette of herbs, and some new experiments are on the menu this summer. We amend our garden soil with compost so that the many of the microbialy driven nutrient cycles supply our plants with minerals needed for growth.
If you don’t want worms, ask the grower if they might want your food scraps for their worms. The casts are rich in nutrients, growth promoting substances, beneficial soil micro flora and having properties of inhibiting pathogenic microbes. Nutrient contents in vermicompost such as Total Nitrogen (TN), Total Phosphorus (TP) and Total Potassium (TK) were determined for day 1, 7, 14 and day 21. The HA showed, also, a small or developing peaks at more acidic pH values (< 4), indicating, probably, a presence of stronger acidic sites.
Vermicompost is stable, fine granular organic manure, which enriches soil quality by improving its physicochemical and biological properties. Results showed that vermicomposts produced by tiger worms gradually possessing higher nutrient contents as the composting process progressed.
The averagecumulative moisture content of MSS as collected from the site was 60-70% (wet basis). If there is no local source, you can often find bags of worm castings at nurseries, and they can be ordered online as well.
In addition conversion of MSS to vermicompost was found to be 93% by weight and worm biomass showed 30% increment from its initial weight within 21 days.
The initial temperature of the sludge was measured as about (27-29)°C and it remained constant for a couple of days.
Thus, the present study showed vermicomposting of MSS into organic fertiliser is feasible besides providing a safe and practical disposal method for sewage sludge.
The HA was extracted from the amendments samples and from an Entic Haplustol and analyzed the chemical and physicochemical characteristics by several analytical methods. In this way, is possible to assume that the HA have a large chemical heterogeneity or are a complex mixture of organic compounds produced during the original material decomposition. The concentration of each acidic sites and therefore, their buffer capacity contribution (height of the peaks), would be very low if the organic amendment is used at this time of the process.
Temperature and moisture content were maintained and the data was recorded thrice a week as shown in Table 1.On the other hand, the characterization of treated sewage sludge was done before and after it was fed to the worms. Sludge characterization includes physical parameter of pH and chemical properties of Total Nitrogen (TN), Total Phosphorus (TP) and Total Potassium (TK). Carbon and nitrogen dynamics in ageing earthworm casts in grasslands of the Eastern plains of Colombia. Both maxima are higher and narrower than those observed for HA-TRM, indicating that the content of both acidic site increases significantly through this period of the process (90 days) and have a lower chemical heterogeneity and more differentiation between both classes of acidic sites. The presence of negative charges permit to separate EtA by electrophoresis in electrical field (+) to (-) in which the EOF (electroosmotic flow) is responsible for the movement of the analyte (Peuravouri et al, 2004).
This behaviour could be used as a marker of the humification process, taking place during the stabilization-maturation process. The vermicast was sieved with hand sorter (net mesh or gauge wire) in order to separate the earthworm and vermicast before its weight was taken. These characteristics are in agreement with that shown by the other analytical techniques employed to study these humic acids. Then, 1 g sample (vermicast) was added into 1 L distilled water for laboratory analyses works. This behaviour suggests an increase in the total aliphatic C and polysaccharides at the end of vermicomposting suggesting neosynthesis in the vermicompost (Sen and Chandra 2007).
The combination of composting and vermicomposting has recently been considered as a way of achieving stabilized substrates. Composting enables sanitization of the waste and elimination of toxic compounds, and the subsequent vermicomposting reduce particle size and increases nutrient availability (Lazcano et al., 2008). Soil application of an unstable organic amendment can harm plant, by the phytotoxic compound production, deficiency of nitrogen and oxygen concentration, thus the plant yield would be reduced (Senesi et al., 2007). The change in the charge development in this range of pH, for the HA analyzed, was similar to that observed for the former acidic groups. In general, the total acidity increase about 7080% during the composting period and about 20-25% in the vermicomposting phase.
This tendency indicate that during this period of the process (first 90 days) occur the principal changes in this physicochemical property in the HA macromolecule, and suggest that during the composting phase take place the most important oxidative process. Some methodologies and techniques are proposed to study HA-like fraction of the organic amendments. During the composting process the thermophilic phase took place for 30 days, the process was carried out for 60 days more (maturation phase), (90 days was the final age for the composting process). The outdoor pile was turned every 15 days during the composting process in order to improve the O2 level inside the pile.
Pile moisture was controlled weekly by adding enough water to obtain moisture content not less than 50 % in composting phase.
The vermicomposting process was carried out for 120 days more (total time for composting followed by vermicomposting process was 210 days). At the end of the vermicomposting process (210 days named VRM) 10 sub samples were collected at 25 cm depth in the worm bed, and then mixed to obtain the composite sample. Soil and each organic amendment (TRM, CRM, and VRM) composite samples were air-dried, crushed and passed through a 2 mm sieves before all the analytical analysis. Total Organic Carbon (TOC) was analyzed by combustion at 540 0C for 4 h (Abad, et al., 2002).
Total nitrogen content (TN) in soil, and organic amendments were obtained by the Kjeldahl method.


The carbon content of humic substances (CHS), humic acids (CHA) and fulvic acids (CFA) were determined according to the technique proposed by Syms and Haby (1971). Chemical and physicochemical characteristics of humic acids extracted from compost, soil and amended soil. The carbon content of each fraction (C , C and C ) were calculated as HS HA FA percentage of the TOC, therefore, the % CHA correspond to the Humification index (HI) (Roletto et al, 1985).

Evolution of organic matter during composting of different organic waste assessed by CPMAS 13C NMR spectroscopy. An aliquot containing the desired amount of HA (=7-8 mg) was transferred to the titration flask containing 10 mL of tridistilled water. The pH values were measured with an Orion Research 901 pH meter equipped with a glass-combined electrode (Orion 9103 BN). The same titration was followed in absence of HA (reference or blank titration) for each titration curve, in order to subtracts it from the raw data titration, and thus obtain the charge developed by the HA sample. Each HA solution, with the corresponding blank solution, was titrated by triplicate and the reported data representing the average values. Characterization of humic acids originated from argentinean compost and soil by capillary electrophoresis and mass spectrometry. Operation of the instrument, data collection and analysis were controlled by Agilent ChemStation software.
The polarity was negative, voltage of -10kV, temperature 250C, total run time 20 min (for time migration higher than 20 min no significant peak were observed). The absorbance was monitored at three different wavelengths (243 nm, 214 nm and 260 nm) and 243 nm was selected to report.

At the end of the daily work, the capillary was rinsed with BGE for 5 min and water for 10 min, at the same temperature and pressure condition.
Chemical and physical characteristics of humic and fulvic acids extracted from soils of the Mediterranean region. Total organic carbon (TOC) and total nitrogen (TN) in the sample at thermophilic phase (TRM) was high, however, both contents decreased after the vermicomposting process (Table 1). The decreasing in TOC was about 35% between the thermophilic phase and the composting process and during the vermicomposting process the loss of TOC was lower (~ 6%). The TN content in VRM was practically the same than in CRM, which indicate that in this period (vermicomposting) the content of N compounds was degraded at lower rate than in the former phase of the process (composting) or probably the N contribution from the biological activity (urine and feces) of the earthworms could balance the lost trigged by the degradation (Gajalakshmi et al., 2005).
