Název v původním jazyce

The influence of long-term sewage sludge application on the activity of phosphatases in the rhizosphere of plants

Popis výsledku v původním jazyce

Model experiments using rhizoboxes were carried in order to evaluate the influence of different plants (wheat, rape) on the changes in water extractable contents of P, the pH/H2O value and the activity of acidic and alkaline phosphatase in soil of plantrhizosphere. For this experiment, a Cambisol with different long-term fertilizing systems was used: (i) control (without any fertilizer application), (ii) sewage sludge, (iii) manure. A lower content of water-soluble P was observed in the close vicinities of root surfaces (up to 2 mm) at all the studied variants. The control (non-treated) variant reflected a significantly lower content of water-soluble P in the rhizosphere compared to the fertilized ones. The activities of the acidic and alkaline phosphatases were significantly higher in the rhizosphere compared to the bulk soil (soil outside the rhizosphere). The long-term application of organic fertilizers significantly increased phosphatase activity. The activity of the acidic phosph
