Türkiye’de Tarımsal Kaynaklı Yeraltı Suyu Nitrat Kirliliği

Abstract

Nitrate contamination of groundwater has become an important Nitrate (NO3-) is the most important species of nitrogen found in the
groundwater. Besides NO3- leaching from agricultural areas due to improper use of fertilizers and irrigation water, considerable amount
of NO3- originated from industrial and municipal areas move through the vadoze zone and reaches to groundwater. It is more difficult to
detect NO3- originated from large agricultural areas and to evaluate its impacts on groundwater compared to industrial and municipal
sources. Studies showed that NO3- concentration is progressively increasing in Turkish groundwaters due to intensified fertilizers and
irrigation water use and coming from industrial and municipal sources. In this study, we summarized the groundwater contamination of
NO3- from agricultural activities and measures taken to lessen its impact on groundwater in Turkey.
