Abstract
A field experiment was conducted to evaluate the effect of iron (Fe) chlorosis on the mineral composition of lemon tree leaves cultivated in calcareous soil in the region of Murcia, Spain. A Fe‐polyflavonoid was employed as fertilizer to control Fe deficiency. The evolution of the leaf content in Fe, potassium (K), sodium (Na), magnesium (Mg), calcium (Ca), phosphorus (P), manganese (Mn), and zinc (Zn) was monitored during all the sampling cycle. A high correspondence between total Fe and chlorophyll content could be appreciated. A multivariance analysis was performed with the data obtained, showing that Fe was correlated with P, Mn, and K.
