EFFECT OF VARIED SOIL Ca/Mg RATIOS ON Ca AND Mg CONCENTRATIONS IN LEAF SAMPLES OF TWO APPLE CULTIVARS
View through CrossRef
A range of soil Ca/Mg ratios was established to a depth of 1 m on 3 × 3-m sandy loam tree sites before planting 2-yr-old Macspur McIntosh/M.26 and Northern Spy/M.26 spring 1980. Leaf Ca increased and leaf Mg decreased with increase in soil Ca/Mg in each of the years 1980–1982. Leaf composition (leaf Mg, leaf Ca and leaf Ca/Mg) was highly correlated with soil composition (soil Mg, soil Ca, soil Ca/Mg) and log10 soil Ca/Mg). The relationship between leaf composition and soil Ca/Mg was logarithmic, i.e. the effect of unit increase in soil Ca/Mg on leaf composition decreased as the ratio increased. Soil Mg accounted for as much variation in leaf composition as did log10 soil Ca/Mg; up to 88% when leaf composition was expressed as a ratio. A decrease in soil Mg of 1 meg/100 g soil, accompanied by a similar increase in soil Ca, was associated with an increase in leaf Ca of 0.10% and a decrease in leaf Mg of 0.06%.Key words: Leaf calcium, soil calcium, leaf magnesium, soil magnesium, apple
