Nitrate has been accumulated in natural sources and soil and water have been contaminated as a result of uncontrolled applications conducted in the stages of storage of manure, processing and spreading it on the farms in stockbreeding enterprises. The purpose of the study is to search the effect of manure obtained from stockbreeding enterprises on the shallow ground water and emphasize the possible damages caused by this influence. Water samples were taken from the ground water observation wells and regular nitrate analysis were made in the experiments conducted in two different enterprises in one of which dairy farming is done and in the other livestock farming is conducted. In Farm I, the highest nitrate value was measured as 54,63 mg/L in January and the lowest nitrate value was measured as 1.13 mg/L in July. In Farm 2, the highest nitrate value was measured as 52.24 mg/L again in January and the lowest value was measured as 1.35 mg/L in July. The accumulation of their waste on the soil causes the increase of nitrate concentration in shallow ground water. It has been detected that the increase in these concentrations exceeds the standard values especially after the rainy days and this issue has become a serious contamination factor for water resources.
