Effects of Sewage Sludge on Marigold (Tagetes erecta L.) and Garden Verbena (Verbena hybrida) Plants and Soil

Abstract

ABSTRACT This study was carried out to determine effects of granular sewage sludge treatments on plant nutrients contents and heavy metal levels of marigold (Tagetes erecta L.) and garden verbena (Verbena hybrida) ornamental plants. Pot-experiments conducted under greenhouse conditions and experimental treatments included 0% (control), 3% SS, 6% SS and 9% SS treatments. The bioconcentration factor (BCF) values for Ni, Cd, Cr and Hg of marigold and Cd and Hg of garden verbena were ≥0.2 indicating that these plants could be used for remediation contaminated soils. In marigold and garden verbena plants, the greatest plant N, P, K, Mg and Ca value were respectively obtained from 9% SS and 6% SS treatments. In marigold plants, the greatest Na (784 mg kg-1) was obtained from 9% SS treatment, Fe (2236 mg kg-1) from 9% SS, Cu (7.4 mg kg-1) from 9% SS, Zn (136 mg kg-1) from 6% SS, Mn (142 mg kg-1) from 6% SS and B (42 mg kg-1) from the control treatments. In garden verbena plants, the greatest Na (696 mg kg-1) was obtained from 6% SS treatment, Fe (1700 mg kg-1) from 6% SS, Cu (12 mg kg-1) from 6% SS, Zn (115 mg kg-1) from 6% SS, Mn (100 mg kg-1) from 3% SS and B (47 mg kg-1) from the control treatments. In terms of heavy metals (Ni, Cd, Cr, Pb, As and Hg), toxicity impacts were not encountered in marigold and garden verbena plants. Soil heavy metal (Ni, Cd, Cr, Pb, As and Hg) levels were all below the threshold values.
