Implication

Laboratory experiment demonstrates reduced phytotoxicity following compost addition in white mustard, indicating an effective strategy for safe sewage sludge utilization.

Key Points

To evaluate the phytotoxicity of sewage sludge from two wastewater treatment plants in the Czech Republic and assess the mitigating effects of compost addition on plant root growth.
Tested sewage sludge phytotoxicity at concentrations of 10%, 30%, and 50% using the Phytotoxkit assay on white mustard (Sinapis alba L.) root growth across three replicates.
Evaluated the impact of compost addition to sewage sludge at ratios of 5%, 15%, 25%, and 50% on root development in triplicate.
Stimulation of white mustard root growth occurred only at the lowest tested sludge proportion of 10%, with higher concentrations exerting inhibitory effects.
Compost addition reduced sludge phytotoxicity and suppressed root growth inhibition across all evaluated mixture ratios (5%, 15%, 25%, and 50%).
