[Proposal for the introduction of microbial test material in compost windrows for field test (author's transl)].

The introduction and taking of microbial test material for field tests in compost windrows for e.g. the determination of the death rates of patogenic microbes cause various problems in practical use whereby the results of such investigations may be influenced. A device is suggested which allows unlimited microbes taking with the greatest reservation of the windrows and guarantees that during the experiment the introduced microbial test material is actually exposed to the same influences as its neighbouring windrow parts. Comparisons with other methods used are being made.
