Lettuce(Lactuca sativaL.)collected from eleven trials with different rates of application of ammonium nitrate limestone was analysed for bromide. Nitrogen application (0–2.6 kg N/100 m2) decreased the bromide content of the lettuce in most trials. This decrease varied from 0 to 50%, with 27% as the average. A correlation was found between the bromide content of the crop and that of the soil extract at the conclusion of the trials. The correlation could be improved by calculating a multiple regression equation which included the nitrate content of the soil extract.
