Micro-Structure of Iron in \textbf{\textit{Petroselinum crispum}} and its dependence with the chemical nature of the soil.*

The micro structure of the iron Iron in \textbf{\textit{Petroselinum crispum }} is investigated using synchrotron X-ray Absorption and Mossbauer spectroscopy. Plants were grown under controlled soil conditions with different pH, and iron concentrations. The correlation between the micro structure of the iron in \textbf{\textit{Petroselinum crispum}} plants and the soil conditions were studied. Most of the iron present in the plants has the form Fe$^{\mathrm{3+}}$ or electron density at the site of the iron nucleus similar to that of Fe$^{\mathrm{3+}}$. But the amount of iron absorbed by the plants depends on the soil conditions. These findings will help establish soil conditions necessary to increase Fe$^{\mathrm{2+}}$ intake by plants similar to the form of iron present in most supplements.
