“…Vegetable uptake is believed to be a cost-effective way to improve human nutrition and to help reduce the incidence of IDD (Cao et al, 1994;Jopke et al, 1996;Jiang et al, 1997;Zhu et al, 2003;Dai et al, 2004b). However, the availability of iodine for plant uptake and its migration depend largely on its interactions with various soil components (Yoshida et al, 1992;Hu et al, 2005).…”

“…Supplementation of trace elements in the food chain through plant uptake is generally termed biofortification and is believed to be a cost-effective way to improve human nutrition (3). Iodine supplementation in the food chain has been attempted recently in Xinjiang-for example, by the irrigation of paddy soil with iodized water to reduce iodine deficiency (4).…”

A greenhouse pot experiment was conducted to select vegetables for iodine uptake. The residual effect of iodate fertilization on the growth of and iodine uptake by spinach plants were also investigated. Results showed that the concentrations of iodate in soil had significant effect on the biomass of edible parts of pakchoi and spinach (p<0.01), whereas the concentrations of iodate in soil had no significant effect on that of carrots, water spinach, celery, and onion. Iodine concentrations in edible parts of vegetables and the transfer factors (TF edible parts ) of soil-to-edible parts of vegetables significantly increased with increasing iodine concentrations in soil (p<0.001), and iodine concentrations in edible parts and TF edible parts of spinach were much higher than those of other vegetables at any treatment. Both transfer coefficients for edible parts (TC edible parts ) and for aerial parts (TC aerial parts ) of vegetables changed differently with increasing iodine concentrations in the soil, and TC edible parts and TC aerial parts of spinach were higher than those of other vegetables. Therefore, spinach (leafy vegetable) was considered as an efficient vegetable for iodine biofortification. Further experiment showed that there is considerable residual effect of soil fertilization with iodate.

“…Animals and plants in the food chain ultimately depend upon soil, water and rock in the environment for the provision of essential minerals to meet the human need. Therefore supplementation of iodine in food chains through plant uptake is believed to be a cost-effective way to improve human nutrition and help to reduce the worldwide incidence of IDD (Jopke et al 1996).…”

Availability of iodide and iodate to spinach (Spinacia oleracea L.) in relation to total iodine in soil solution

et al. 2006

A greenhouse pot experiment was carried out to investigate the availability of iodide and iodate to soil-grown spinach (Spinacia oleracea L.) in relation to total iodine concentration in soil solution. Four iodine concentrations (0, 0.5, 1, 2 mg kg -1 ) for iodide (I -) and iodate (IO 3 -) were used. Results showed that the biomass productions of spinach were not significantly affected by the addition of iodate and iodide to the soil, and that iodine concentrations in spinach plants on the basis of fresh weights increased with increasing addition of iodine. Iodine concentrations in tissues were much greater for plants grown with iodate than with iodide. In contrast to the iodide treatments, in iodate treatment leaves accounted for a larger fraction of the total plant iodine. The soil-to-leaf transfer factors (TF leaf ) for plants grown with iodate were about tenfold higher than those grown with iodide. Iodine concentrations in soil solution increased with increasing iodine additions to the soil irrespective of iodine species. However, total iodine in soil solution was generally higher for iodate treatments than iodide both in pots with and without spinach. According to these results, iodate can be considered as potential iodine fertilizer to increase iodine content in vegetables.
