Summary Fixed doses of K and increasing doses of Ca and Mg in different proportions were added to a senile latosol. The resulting cationic nutrient potentials were correlated with the uptake of these cations by tomato and with the cationic ratios in the plant material. Highly significant correlations were found between the nutrient potentials pK-0.5pCa, pK-0.5pMg, pK-0.5p(Ca + Mg) and pCa-pMg on one hand and the respective logarithms of K/Ca, K/Mg, K/Ca + Mg, and Ca/Mg in the plant material, on the other hand. Soil samples taken before planting showed higher correlation coefficients than did samples taken after harvesting. The valuesΔpCa andΔpMg, being the differences in nutrient potential between soil samples taken before and after the growth period, correlated significantly with the corresponding totals of absorbed ions.
