AbstractThe effect of periphyton propagation in paddy fields on phosphorus biogeochemical cycling has received little attention. In this phytotron study, inorganic phosphorus (P-i) accumulation by periphyton was investigated for varying inputs of calcium[Ca(II)] or ferrous iron [Fe(II)], and lighting conditions. Results indicated that additions of Ca(II) or Fe(II) enhanced abiotic accumulation of P-i by up to 16 times, and decreased solution P-i concentration by up to 50%, especially under light condition. The enhanced P-i accumulation into periphyton intensified with increasing P-i concentration, and P-i accumulation showed a positive linear relationship with Ca or Fe accumulation. Abiotic accumulation of P-i induced by Ca(II) was mainly through Ca-phosphate precipitation, and co-precipitation of P with carbonates at pH > 8. Accumulation with added Fe(II) was mainly considered to be through Fe(III) phosphate precipitation coupled with adsorption of P-i by ferric hydroxides. Moreover, Fe(II) was more effective than Ca(II) in promoting abiotic accumulation of P-i by periphyton. Our results indicate the potential for controlling environmental factors to enhance the role of periphyton in biogeochemical cycling and P-use efficiency in paddy rice fields and to reduce P discharged to neighboring water bodies.
