  1. Data presented as dry weight normalised shoot ionomics data obtained by inductively coupled plasma optical emission spectroscopy (ICP-OES) as per [19, 20] on 5 week old Col-0 shoots grown in soil (the PiiMS database: soil-grown plants fed ½-strength MS media; n=125 plants) and our hydroponics system (n=12 plants). Ratio compares ionome of hydroponics plants to soil-grown plants showing lines are similar in nutrient content for most elements, excluding Zinc, in the shoot. Detection limit shown for Cr, Co, Ni, Se and Cd, n.d.: not determined as one or both readings were given as a detection limit (note in all these cases the ranges overlap).
