The field experiment was conducted at Tinsukia in Assam of India during kharif seasons 2016-17 and 2017-18 to investigate the effect sowing date nitrogen (N) management practices on growth yield green gram (Vigna radiata L.). Results indicate that date, S2 (1st September) showed superiority respect crop, compared other dates for both years. Amongst N treatments, a significantly higher value par...

Inoculating two kinds of microbes (MS compound strains and ZHJ fermentation), study on the effect of the MSW compost on the nitrogen and maturity, the results showed, comparing with that of compost primary, the content of total nitrogen obviously declined at the end of the MSW compost. The two kinds of microbes could accelerate the transform of water-soluble NH4-N and the formation of the water...

Peanut haulms compost as a carrier of three Trichoderma species (T. harzianum, T. hamatum and T. koningii) exhibited different morphological and chemical characteristics and its ability to control Fusarium wilt of cumin plants caused by Fusarium oxysporum compared with peat/vermiculite. The peanut haulms carrier was able to increase the population size, numbers, viability, survival, microbial b...

In order to set a reference inventory data, an extensive literature search on compost production and compost utilization has been performed. The aim is to define carbon and energy footprint of bio-waste recycling and compost utilization. The available data suggest that when bio-waste is properly collected and recycled (through composting or anaerobic digestion) and a high quality compost is pro...

The common practice of remediating metal contaminated mine soils with compost can reduce metal mobility and promote revegetation, but the effect of introduced or colonising earthworms on metal solubility is largely unknown. We amended soils from an As/Cu (1150 mg As kg(-1) and 362 mg Cu kg(-1)) and Pb/Zn mine (4550 mg Pb kg(-1) and 908 mg Zn kg(-1)) with 0, 5, 10, 15 and 20% compost and then in...

Compost amendment to contaminated soils is a potential approach for waste recycling and soil remediation. The relative importance and interactions of multiple factors on PAH bioavailability in soils were investigated using conjoint analysis and five-way analysis of variance. Results indicated that soil type and contact time were the two most significant factors influencing the PAH bioavailabili...

In 2005, the US Environmental Protection Agency National Menu of Stormwater Best Management Practices, National Pollutant Discharge Elimination System Phase II for Construction Sites, listed compost filter socks as an approved best management practice for controlling storm runoff and sediment on construction sites. Like most new technologies used to control sediment on construction sites, littl...

The content, behaviour and significance of heavy metals in composted waste materials is important from two potentially conflicting aspects of environmental legislation in terms of: (a) defining end-of-waste criteria and increasing recycling of composted residuals on land and (b) protecting soil quality by preventing contamination. This review examines the effects of heavy metals in compost and ...

Alkane degrading microorganisms play an important role for the bioremediation of petrogenic contaminated environments. In this study, we investigated the effects of compost addition on the abundance and diversity of bacteria harboring the alkane monooxygenase gene (alkB) in an oil-contaminated soil originated from an industrial zone in Celje, Slovenia (Technosol). Soil without any amendments (c...
