A comparison of uptake and concentration of iron (Fe) in wheat (Triticum aestivum L.) plant using ordinary and nano iron oxides

Comparison of uptake and concentration of iron (Fe) in wheat (Triticum aestivum L.) plant using ordinary and nano iron oxides of Folade Mobarake Esfehan wastes in soil was carried out in a factorial completely randomized design with three replications. Ordinary iron oxide (0. 02-0. 06 mm) and nano iron oxide (25-250 nm) were used at (0، 0. 05، 0. 1، 0. 5، and1. 0 % w/w) and two levels of urban solid waste compost coated with sulfur (0 and 2% w/w). Results showed that the uptake and concentrations of Fe in wheat increased significantly by using nano iron oxide more than that of ordinary iron oxide. Also، with increasing both iron oxides levels the uptake and concentrations of Fe in wheat increased significantly. Urban solid waste compost coated with sulfur increased the uptake and concentrations of Fe in wheat significantly. Application of both iron oxides along with urban solid waste compost coated with sulfur resulted in a significant increase in the uptake and concentrations of Fe in wheat. This increase was much more in treatment of nano iron oxide with urban solid waste compost coated with sulfur than that of ordinary iron oxide with urban solid waste compost coated with sulfur.
