Abstract

High concentrations of phosphate in plants cause a typical iron deficiency chlorosis with characteristic mineral and biochemical patterns. Studies show that organic acids in leaves are involved in the absorption and distribution of minerals, particularly calcium and potassium, and that their behavior is controlled by an iron-phosphate balance.
