Abstract
Band application of MgCl2·6H2O under the tree canopy of ‘Shamouti’ orange [Citrus sinensis (L.) Osbeck] trees significantly increased leaf Mg and Cl concentration. MgSO4 and MgO were not effective. Fertigation with MgCl2·6H2O was less efficient than band application and was not superior to foliar application of Mg(NO3)2·6H2O for increasing leaf Mg concentrations. In spite of high Cl concentration of the leaves, no visible toxicity symptoms were observed.
