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...

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 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...

Little is known about the interaction between inoculation of diazotrophic bacteria, variety, and substrate used in inoculated sugarcane seedling production. Bearing this mind, aim study was to evaluate effects bacteria inoculation, four varieties different substrates on growth nitrogen accumulation seedlings. Parameters related sprouting, height, root growth, as well accumulation, were evaluate...

Andrographis paniculata (Burm.f.) Nees is a medicinal herb in the family Acanthaceae. The leaves of the mature plant contain abundant diterpinoids of medicinal properties.The objectives of the present study were to investigate the impacts of compost tea rates on photosynthesis parameters and antioxidant reactions of A. paniculata. The plant was propagated using seed and planting in a polybag. A...

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 ...

Sugarcane (Saccharum spp. hybrids) has great potential as a major feedstock for biofuel production worldwide. It is considered among the best options for producing biofuels today due to an exceptional biomass production capacity, high carbohydrate (sugar + fiber) content, and a favorable energy input/output ratio. To maximize the conversion of sugarcane biomass into biofuels, it is imperative t...

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...
