Studies on the influence of nutrition on the susceptibility of plants to SO 2 . The mineral nutrition of plants is of great importance for their susceptibility to air pollutants. Substrate media with ammonia as nitrogen source, deficiency of potassium and low pH‐values reduce the buffer capacity and the cation contents. Buffer capacity and cation contents play important roles for the detoxification of SO 2 ‐borne products. Low cation contents and a reduced buffer capacity produce a severe increase of the SO 2 ‐effects. Decreased sulfur nutrition results in a considerable delay of the beginning of the SO 2 ‐injuries.
