ABSORPTION OF MAGNESIUM BY McINTOSH APPLE LEAVES AS INFLUENCED BY SPRAY COMPOSITION AND WEATHER CONDITIONS
Year: 1973
Type: article
Abstract: Addition of Ca(NO3)2 to sprays of MgSO4 increased absorption of Mg by McIntosh apple leaves. Addition of urea had no effect. Absorption of Mg over 24 h from MgSO4 varied from − 2.5 to 19.4% of initial spray deposit and was significant in only one of five sprays. Absorption from Mg(NO3)2 varied from 18.3 to 50.2% and was significant in all sprays. Most of the variation in absorption could be explained by humidity and temperature conditions during the period of absorption.
