Production and utilisation of Anaerobic Digestate Compost from domestic wastes for the improvement of soil quality

摘要

Organic fraction of municipal solid waste (OFMS W) is a rich substrate for biogas and compost production. Anaerobic Digestate compost (ADC) is an organic fertilizer produced from stabilized residuals of anaerobic digestion of OFMSW. This paper reports the results of studies carried out to optimise the production of ADC from organic fractions of domestic wastes and the effects of ADC amendments on soil quality. In generally, ADC amended soils showed greater bioactivity and soil biomass. It was also found that seed germination in ADC amended soils increases with dilution and incubation time, suggesting that lower ADC application rates and longer lag periods between soil applications and planting can improve the benefits of ADC as soil amendment.
