Changes of enzymatic activity during a large-scale vermicomposting process with continuous feeding

Popis výsledku v původním jazyce

The presented experiment determined the enzymatic activity of eight different enzymes in three types of aged vermicomposts (from household biowaste, malt house sludge mixed with agricultural waste, grape marc). The vermicomposting was conducted in the large-scale systems of heaps with continuous feeding of the earthworms, which is applicable in practice. All vermicomposting heaps were divided into five layers of different depths, depending on the age of these layers. In all heaps, the highest number and biomass of earthworms occurred in the youngest layers, as did the highest activity of bacteria or fungi. The highest activity of all eight measured enzymes occurred in the vermicomposting process with household biowaste. The lowest activity of all enzymes showed the arylsulphatase, which did not exceed 66 umol MUFS.g-1.h-1. The highest enzyme activity was detected for lipase, where all values were higher than 5,382 umol MUFY.g-1.h-1. There were marked differences between the layers in all vermicompost
