The Effects of Several Amendments on Forms of Lead and Its Uptake by Two Cultivars of Brassica Chinensis in an Acid Red Soil
We conducted a greenhouse study to examine the effects of various amendments on forms and bioavailability of Pb in red soils, and the differences in responses of two cultivars of Brassica Chinensis with contrasting resistance to Pb. The results showed that red soils with Pb contamination could be remedied by the amendments, and the uptake of Pb in plants could be decreased. The growth of plants was affected by the bioavailable forms of Pb and soil pH. The two cultivars differed in responses to the treatments. The best treatment was calcium magnesium phosphate which immobilized Pb to more residual forms, and significantly reduced the uptake of Pb in plants.
