The research evaluated the comparative effect of two media of soil acidification on lead (Pb), cadmium (Cd), and zinc (Zn) extractive ability ofTithonia diversifoliain alkaline soil. Application of both amendments increased the solubility of the metals. Sulfur (S) addition was more effective at reducing the soil pH compared with the addition of urea. Lead and cadmium uptake by the plant was significantly higher in the urea treatments compared with sulfur treated soils. Generally, the addition of urea resulted in a higher amount of lead and cadmium in the plant parts. The acidification effect due to S addition was too high for the plant to perform optimally. The addition of S increased the uptake of Zn by the plant compared with the effect of adding urea. The complimentary effect of N addition with the soil acidification enhanced metal uptake.Tithonia diversifoliawas classified as a hyper accumulator of metals. [ABSTRACT FROM AUTHOR] |
