Generation of organic wastes has been increased in an unprecedented rate in India with rapid population expansion, leading to disposal problems. These organic wastes can be converted into valuable wealth by applying vermicomposting technology. Vermicompost which provides macro and micro nutrients to the plants, also reduces pollution by providing a valuable substitute for chemical fertilizers. Present paper deals with vermicomposting of organic wastes from seven different sources and evaluation of nutrient in those vermicomposts following chemical analyses. These seven sources include coconut coir, water hyacinth, mixed materials, cabbage, banana pseudostem, cow dung, and rice husk. Three composting species of earthworms e.g.Eisenia. fetida, Eudrilus. eugeniae, andPerionyx excavatuswere chosen for the experiment. Chemical analysis of vermicomposts under study clearly showed that the vermicompost from water hyacinth contained maximum amount of organic C, total N, and total K though the phosphorous content was maximum in vermicompost from mixed materials. Lowest nutrient content was observed in vermicompost of coconut coir. Vermicomposts from mixed materials, cabbage, banana pseudostem were at per in their chemical properties. It can be concluded that among the seven sources, vermicompost from water hyacinth is best for its nutrient value.

Abstract Vermicomposting potential of waste biomass of potato crop that are generated at the time of harvesting was studied employing Eisenia fetida. The experiment was carried out in pots taking two treatments; in one only potato plant biomass (PPB) was taken as raw materials whereas in the other a mixture of PPB with cow dung was engaged in the proportion of 5:1. The vermicomposted materials showed a reduction in C/N ratio, humification index, enhancement in nutrients profiles, ash contents, nitrogen-fixing, phosphate and potassium solubilizing bacterial population. The macronutrient enhancement in the vermicompost samples was recorded 3.8-4.4 fold for total N, 5-5.6 fold in available P, 1.6 fold in total K, 5.2-6.2 fold in total Ca and 1.6 fold in total Mg contents. The reduction in C/N was found in the rage of 92.5-94.4% in the vermicompost samples. The scanning electron microscope (SEM) images showed higher disintegration in the vermicompost products when compared with initial raw material and compost samples. Addition of cow dung significantly enhanced the quality and quantity of vermicompost final products besides positively affecting the earthworm population and biomass by the end of 60 days of experimental trials.

The success of the corn agro-industry is greatly influenced by fertilizeravailability. A notable effort to support that situation is to increase compost production through the utilization and processing of beef cattle and corn wastes. Thisresearch proposed to produce compost from the utilization of beef cattle and corn wastes by following the Indonesian National Standard (SNI). The composting process was carried out by preparing several materials consisting of beef cattle manure (BCM), wet/dry stover (WS/DS), and EM4 solution. These materials were fermented anaerobically, then checked and stirred every three days.The fermentation was stopped after 40 days. This study used a Randomized Block Design (RBD) consisting of five levels of compost materials treatments, namely P0, P1, P2, P3, and P4, with three replications. The parameters observed were the characteristics of cattle and corn waste, the physical feature of the compost, and the nutrient content of the compost (yield, water content, pH, P2O5, K2O, organic C, total N, and C/N ratio). P2 treatment (BCM:WS:DS:EM4 =1:2:1:1) produced compost with the best characteristics, namely blackish brown color and crumbly with slightly sour aroma. The yield obtained was 32.95%, water content was 10.08%, pH was 5.59, P2O5was 0.50%, K2O 1.26%, organic C was 52.34%, total N was 1.34% and C/N ratio was 39.06. These characteristics are by following under the SNI cheap, practical in manufacture and application in the field, and environmentally friendly.

Screening tests are basic procedures commonly used to assess compost quality. Important parameters for quality assessment are the germination capacity and the suppression of plant pathogens which have to be measured by time-consuming laboratory methods. The objective was to test whether visible (vis) and near infrared (NIR) spectroscopy (vis-NIR) is useful to analyse parameters important for compost quality. Ninety seven compost samples from Switzerland were analysed by conventional methods and by vis-NIR. The content of organic (Corg) and inorganic C (Cinorg), total N (Ntot), mineralisable N after 56 days (Nmin_d56), total P (Ptot), K, Ca and salt, the C/N ratio, pH and microbiological characteristics [hydrolysis of fluorescein diacetate (FDA-hydrolysis) as indicator of total enzyme activity and cellulase activity] were determined. Furthermore, plant tolerance and the suppression of pathogens were tested using germination tests with salad, cress, ryegrass and bean or a Rhizoctonia solani bioassay, respectively. The samples were scanned in the range of 400–2500 nm (visible light and NIR) using a Foss NIRSystems spectrometer 6500. A modified partial least squares regression method and the whole spectrum were used to develop cross-validation equations for all constituents. For this, the first to third derivative was calculated. The prediction accuracy was evaluated as excellent for Corg and good for N, and the C/N ratio based on the RSC values (ratio of standard deviation of laboratory results to standard error of cross-validation) and the coefficients of determination ( r2). Approximate quantitative predictions were possible for the contents of Ptot, K, Ca and salt, whereas for the constituents Cinorg, Nmin_d56, FDA-hydrolysis and the germination tests with cress and salad only between high and low values could be discriminated. Unsuccessful predictions as indicated by RSC values lower than 1.5 and r2 values below 0.50 were obtained for pH, cellulase activity, germination tests with ryegrass and bean and the disease suppression test using R. solani. Overall the results of the present study indicate that vis-NIR spectroscopy has the potential to be used for quality assessment of composts and to replace time-consuming methods such as germination tests using salad and cress. However, the use for monitoring purposes requires further research to clarify whether other complex quality parameters such as disease suppression indicators may also be predicted successfully.
