Microbial biomass c and ninhydrin-reactive n as Parameters to characterize composting process
The use of compost in agriculture is increasing as a source of organic matter to counteract the decrease of organic matter level in soils and as a means of disposal of agricultural and domestic waste. Despite many researches on the subject, there is still the need to improve our knowledge on the compost process and on the methods to evaluate compost maturity. The composting of organic waste has ...

ANFIS approach to the working of a compost–heat extractor
Composting is an organic sludge management option in which volatile solids are converted to carbon dioxide and water. As the sugar cane press mud undergoes aerobic composting, the bed heats–up to a temperature in the range of 50–70°C, releasing thermal energy and the heat liberated was extracted using a heat pipe. A neural network approach is applied to analyse the data obtained ...

Developing value added bioactive timber waste vermicompost with addition of microbial inoculants
A study conducted at Vermiculture Research Station (VRS), Aligarh, to transform the timber solid waste vermicompost (TSWV) into bioactive compost with the addition of beneficial microbes has brought to light feasibility of a potential technique to develop value added quality product with higher agronomic value for the first–time. TSWV was inoculated with microbes Azotobacter chroococcum, Bacillus ...

Microbial characterisation of vermicompost and compost of urban waste processed by three earthworm species - Eudrilus eugeniae, Eisenia fetida and Perionyx excavatus
Species diversity of bacteria, fungi and actinomyctes of vermicompost and compost of the organic fraction of municipal solid waste, vegetable market waste and flower waste were assessed using pour plate technique. Of the total 91 entities, 62 were bacteria and 29 were actinomycetes in MW, followed by that of MSW and FW, with 59 and 55 bacterial; 25 and 22 actinomycetes entities, respectively. The ...

The influence of biowaste and garden waste composts on diseases caused by pythium ultimum and rhizoctonia Solani related to the antagonists trichoderma hamatum and flavobacterium balustinum
Soilborne plant pathogens can cause serious losses on both agricultural and horticultural crops. Examples include damping-off diseases caused by Pythium spp. and Rhizoctonia spp., Pythium and Phytophthora root rots, Rhizoctonia crown rot, Fusarium and Verticillium wilts, nematode and even bacterial diseases. Until the fifties, the principal methods to control soilborne diseases were through the ...

Effect of feeding efficient microbial community on aerobic composting of municipal waste and excrement
Each of the total 13 strains of bacteria was isolated based on the characteristics of municipal waste and excrement, which include 6 strains of bacterium, 4 strains of streptomyces and 3 strains of actinomycetes; all of these were appropriate for aerobic composting. The Efficient Microbial Community (EMC) was constructed by these strains combination at certain ratios. A series of experiments were ...

Effect of covering composting piles with mature compost on ammonia emission and microbial community structure of composting process
Received for publication February 14, 2008. To control ammonia (NH3) volatilization from the dairy cattle (Bos taurus) manure composting process, a compost pile was covered with mature compost and the gas emissions evaluated using the dynamic chamber system. The peak of NH3 volatilization observed immediately after piling up of the compost was reduced from 196 to 62 mg/m3 by covering the compost ...

Compost stability: a comparative evaluation of respirometric techniques
The new Paradigm in waste management promotes attitudes and processes that conserve resources and reduce pollution. Under this philosophy, organic waste is increasingly recognised as a recyclable material, a useful resource, making composting one of the key elements of modern waste management. As the composting industry is expanding rapidly there is a growing need for a simple, fast, relatively ...

Composting of vegetable waste in subtropical climates
This experiment examined the possibility of using composting as a method of waste disposal in subtropical countries, such as the United Arab Emirates (UAE), where temperatures are high and humidity is low. In order to simulate conditions in the UAE, a representative mixture of wastes generated in the UAE was prepared and tested at ambient temperatures resembling those of subtropical countries. ...

Bio-conversion of organic waste using composting technologies – a review
Composting is nowadays evolving as a highly technical process for processing organic waste separately replacing landfilling along with municipal solid waste. Vegetable waste with high organic content can be composted to produce nutrient rich material that can work as soil conditioner instead of dumping in open landfills. Various studies reveal that due to high organic content of vegetable waste ...

Disposal of seaweed wakame (Undaria pinnatifida) in composting process by marine bacterium Halomonas sp. AW4
A novel marine bacterium, identified as Halomonas sp. AW4 by partial 16S rDNA analysis, was isolated from the seaweeds in Awaji Island, Japan. Strain AW4 grew well even in the wide NaCl concentration ranges of 0?3 mol/L, where it showed an optimal growth in the presence of 0.5 mol/L NaCl. The organic components were reduced to 73.6% of initial dry weight after 168 h of composting by inoculation ...

Composting of municipal green waste using a hybrid Mode of the aerated static pile
The aerated static pile (ASP) system developed in Rutgers University (Finstein et al., 1980) is based on a deep understanding of composting as a microbial process. It allows for a good degree of process control and high organic matter stabilisation rates, with relatively low labour and cost. For these reasons, the ASP system has been intensively studied with, among others, the following aims: ...

A Guide to Compost Sheep Manure for Organic Fertilizer
Sheep manure contains protein, organic acid, cellulose, aliphatics and so on, and its organic matter content is higher other livestock manure. Without fermentation, sheep manure has various harmful bacteria that cannot be directly used on plants growing, or there would bring germs and parasite spreading. What’s worse, without proper disposal, sheep manure would generate heat to consume oxygen in ...

Effects of biowaste compost amendment on soil microbial biomass and specific carbon turnover in agricultural soils
The importance of biowaste compost as organic fertilisers has become more emergent in the last years due to the increased production of compost produced from biowaste. The utilisation of organic fertilisers in agriculture improves the physical, chemical and microbial properties of soils (Allievi et al., 1993; Senesi, 1989). Amendment of compost affects several soil properties positively like e.g. ...

Formation and emissions of ammonia and greenhouse gases from stored and composted solid animal manure
Beside other branches of industry, agriculture is an important source of methane (CH4) and nitrous oxide (N2O) emissions and the most important source of ammonia (NH3). In spite of several investigations concerning ammonia and greenhouse gas emissions during storage and composting of liquid and solid animal manure, the real extent of these emissions is still unknown. This is mainly because of the ...
