Abstract

Abstract: The increased accumulation of lead (Pb) in tea is widely concerned. The study on the factors influencing Pb concentration in tea is necessary for the production of high quality tea. In this study, soils of two tea gardens (Yellowish red soil and Red soil) were collected and incubated by adding acid and organic manure for studying the effects of acidification and organic matter accumulation on Pb bio-availability of tea garden soils. Water-soluble Pb, NH₄OAc extractable Pb and chemical forms of Pb in the incubated soils were characterized. The results showed that soil acidification promoted transformation of other forms of Pb into exchangeable Pb, and thus increased water solubility and bio-availability of Pb in the soils. Accumulation of organic matter could activate Pb in soils with pH>4, whereas accumulation of organic matter decreased Pb bio-availability in lower pH soils (pH<4). The effects of pH and organic matter on Pb bio-availability were more significant in sandy soil than that in clayey soil.

Key words: Soil in tea garden, Acidification, Pb, Organic matter accumulation, Bio-availability
