Effect of synthetic fertilizers and atmospheric precipitation on nitrogen enrichment in surface waters

Effect of synthetic fertilizers and atmospheric precipitation on nitrogen enrichment in surface... The increase of the nitrate concentration in surface waters used as water supply resources has been investigated with a view to the effects of agricultural activities and atmospheric precipitation. The nitrate concentration increased beyond the acceptable limit for infants after 1975, when due to the permanent augmentation of the synthetic fertilizer rates the organic humus quantities decreased to a minimum. The variability of nitrate concentrations in atmospheric precipitation is dependent on the magnitude of precipitation and the intensity of industry in the given region. At an average value of atmospheric precipitation the nitrogen value in agricultural regions varies within 6 to 12 kg · ha−1 · a−1, in regions with extended industries up to 24 kg · ha−1 · a−1. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acta hydrochimica et hydrobiologica Wiley

Abstract

The increase of the nitrate concentration in surface waters used as water supply resources has been investigated with a view to the effects of agricultural activities and atmospheric precipitation. The nitrate concentration increased beyond the acceptable limit for infants after 1975, when due to the permanent augmentation of the synthetic fertilizer rates the organic humus quantities decreased to a minimum. The variability of nitrate concentrations in atmospheric precipitation is dependent on the magnitude of precipitation and the intensity of industry in the given region. At an average value of atmospheric precipitation the nitrogen value in agricultural regions varies within 6 to 12 kg · ha−1 · a−1, in regions with extended industries up to 24 kg · ha−1 · a−1.
