A vegetation experiment (88 days) studied the effect of soil contamination with fly ash produced in hard coal combustion (0.0; 33.3; 66.6; 99.9 g·kg-1 of soil) on the physicochemical properties of soil, the yield of oat (Borowiak) and maize (Reduta), selected soil bacteria count and the activity of soil enzymes: dehydrogenases, urease, alkaline and acid phosphatases. Oat was grown as the main crop...
The aim of the study has been to determine the effect of soil contamination with zinc on the activity of soil enzymes. The study consisted of two laboratory experiments. Same, light loamy soil of pH 7.1, was used in both experiments. The variables in the first experiment were: a degree of soil contamination with zinc in mg Zn kg-1 d.m. of soil: 0, 5, 500, 1000, 1500 and 2000; dose of cellulose in...
This experiment aimed at determining the effect of copper, zinc, tin and barium administered to soil at doses of 4, 40, 400 mg/kg on the contents of macroelements in spring barley and their correlations with the enzymatic activity of soil. The elements applied were found to be the most favourable for nitrogen accumulation in spring barely, however, the most beneficial effect was usually observed at...
The objective of this study was to determine the effect of soil contamination with copper (0 1200 mg kg-1 of soil) on its enzymatic activity and physicochemical properties. An attempt was undertaken to establish a possibility of the application of actinomycetes spores Streptomyces odorifer and Streptomyces viridis in detoxication of such soils. A pot experiment was conducted in two types of soil:...
