abstract:
The applied fertilisation did not diversify chromium concentrations in plants on individual objects. Despite considerable amounts of this element supplied to the soil with tannery sludge its contents only slightly increased in fodder beet. The treatments applied did not increase the content of other heavy metals in plants because of their low concentration in the fertilisers used. The de-acidifying activity of organic fertilisation in the form of farmyard manure and tannery sludge was greater immediately after the application than after three years of experiments. The biggest differences in the content of soluble forms of the metals studied were detected immediately after treatment. Heavy metal solubility depended on the kind of element concerned, whereas the fertilisation used did not cause any excessive mobilisation of heavy metals under investigation.
