A capability to determine the availability of nitrogen in organic amendments is necessary to ensure that such materials will provide sufficient nitrogen to the growing crop and cause minimal environmental degradation. Greenhouse bioassays were used to evaluate N availability of organic by-products, including several employed in the field study of this research. Tall fescue was grown in greenhou...

BACKGROUND Developing cities like Khulna, the third largest metropolitan city in Bangladesh, have now begun to confess the environmental and public health risks associated with uncontrolled dumping of solid wastes mainly due to the active participation of non-governmental organizations (NGOs) and community-based organizations (CBOs) in municipal solid waste (MSW) management. METHODS A survey ...

Urbanization and rapid growth of population in India has led to drastic increase in municipal solid waste. Unscientific disposal of municipal solid waste is one of the main reasons attributed for environmental degradation. The present work concentrates on municipal solid waste management in Tiruchirappalli City which comprises of four zones namely Srirangam, Goldenrock, Araiyamangalam and Abish...

Municipal solid waste management system (MSWMS) includes MSW generation, storage, collection, transfer and transport, processing and disposal. The planning of an optimal MSWM strategy requires a reliable tool for predicting the amount of municipal solid waste (MSW) that is likely to be produced. The MSWMS is a complex, dynamic and multi-faceted system depending not only on available technology ...

Municipal solid waste (MSW) compost contains a significant amount of humic substances. In this study, the compost consisted of residual MSW with the metal, plastic and glass removed. In order to enhance degradation processes and the degree of composting humification, complex microorganisms (Bacillus casei, Lactobacillus buchneri and Candida rugopelliculosa) and ligno-cellulolytic (Trichoderma a...

A cellulolytic, thermophilic actinomycete (previously isolated from municipal refuse compost samples) was identified as Thermomonospora curvata. A determination was made of the optimal conditions for cellulase production by T. curvata when grown at 55 C in a medium containing mineral salts, cellulose, and yeast extract. The pH and temperature optima (pH 6.0 and 65 C) for the cellulase produced ...

evaluation of soil microorganisms and their beneficial relationships among ecosystem components is one of new topic in soil resource management for ensuring sustainable agriculture. in order to investigating effects of trichoderma spp. and different organic manures on improvement of growth and development in soybean [glycine max (l.) merril.], an experiment was conducted at glasshouse in sari a...

Waste accumulation is reported to be one of the serious environmental problems. Organic wastes such as organic fraction of municipal solid waste (OFMSW) or sewage sludge (SS) can be treated using aerobic microbial decomposition called composting. It is important to know when composts obtained in co-treatment processes turns to be safe but not toxic for the environment. In this study, we estimat...
