Recent developments in production of chloride‐free fertilisers prompted a test of effects of chloride on seed germination in soil. NPK nutrient salt mixtures, based on KCl or KNO 3 , were tested at 5 rates, in soil at 0.1 or 1.0 bar water tension at 10°C; other experiments on wheat and maize also used 2 and 3 bar tension and 20°C. Salt and chloride sensitivity varied widely; lettuce, cauliflower and sugar beet were most sensitive to chloride, but wheat and maize were also sensitive at high rates, high temperatures and in dry soil. Germination was never better with chloride‐based than nitrate‐based mixtures.
