Abstract Nutrient culture studies frequently involve the use of balancing ions to equalize concentrations of essential nutrient elements. In a pot experiment in controlled environment with Lupinus angustifolius, growth and nodulation were assessed following calcium treatment (15 mM) using the acetate, chloride and sulphate salts in various combinations. Chloride depressed nodulation at levels higher than 20 mM; nodule mass and number were highest at the maximum sulphate concentration (13 mM). At the lowest sulphate level (2 mM), nodulation and root growth were depressed by 4 mM or higher acetate. Nodulation (dry weight and numbers of nodules) was maximized at 13 mM sulphate/4 mM chloride.
