Soil Fertilization and Nitrate Accumulation in Vegetables¹

Five different rates of nitrogen were applied to plots upon which were grown several different varieties of vegetables. Nitrogen fertilization caused significant increases in nitrate content in red radishes, kale, mustard, and turnip roots and tops. The maximum accumulation of nitrates appeared to vary with species, but differences in harvest dates between species precluded valid statistical tests of the differential accumulations. No significant differences in nitrate accumulation were found between varieties of the same species. Early maturing vegetables tended to accumulate more nitrate than late maturing varieties at a given rate of fertilization. Differences in nitrate content were observed at different sampling dates. The absence of phosphorus, potassium, or lime, or the presence of trace elements in the fertilizer treatment had no significant influence on nitrate accumulation.
