Accumulation of nitrates in vegetables having grown mainly within the limits of the Kremenchug district is exposed in the result of carried out researches. The average and maximum concentrations of nitrates in vegetables were analised. For most vegetables exceeded the MPC only maximum concentrations of nitrate, and the average value of concentration - in the normal range. Causes and factors of nitrate accumulation in crops: non-uniform application of fertilizers spreaders from the use of incomplete, inadequate transportation and storage technologies fertilizers and soil properties, meteorological conditions, morphological and physiological characteristics of individual plants, plant variety, and so on. The measures to reduce nitrate content in vegetable production: the use of slow acting polymeric forms of fertilizers, fertilizer granules coating protective film, capsules, local application of nitrogen fertilizers.
