Calcium-magnesium ratios in the root medium as related to magnesium uptake by citrus seedlings

Plant and Soil Aims and scope Submit manuscript

Summary

A pot experiment was carried out in the greenhouse, on sweet-lime (Citrus aurantifolia) seedlings grown in soils with three Mg/Ca ratios: 0.33, 0.11, and 0.05. Leaf analyses showed positive correlations between Mg/Ca ratios in the medium and magnesium contents, and Mg/Ca ratios in the leaves. Using a split-root technique it has been shown that impaired magnesium uptake at the Mg/Ca ratio of 0.05 in the medium, is not due to its low magnesium contents, but rather to an excess of calcium.
