Aluminium solubility in the presence of citric acid

The present study points to an important role of citric acid in limiting toxicity of aluminium ions for pea plants which was confirmed by the plants’ growth, development and yield. Excess of aluminium influenced plant nutrition with Ca, P, Mg, and K as this toxic element did not only gather in the roots of the studied plants but also in their above-ground parts. Limitation of aluminium toxicity by its complexing with citric acid clearly influenced a increase in the Fe uptake by plants and an decrease in the Mn uptake which was statistically proved.
