Microbiological and biochemical parameters: criteria for evaluating the quality of composts

摘要

To evaluate compost quality, along with traditional agrochemical parameters it is advisable to apply an all-encompassing analysis of compost activity by many biological parameters. The analysis covers the following indices: enzymatic activity, ability to inhibit phytopathogenic microflora, and composition of the microbial cenosis. An all-encompassing method was applied to a comparative study of composts produced from municipal wastes from Sweden, the Czech Republic and from pig farm wastes of the Netherlands. The recommended method will make it possible to expand the spectrum of biocompost application and optimize the technology of its application in sustainable agriculture.
