Özet
The aim of this research conducted in the laboratory, is to determine the effect of ammonium sulfate application applied to twenty soil samples with different physical and chemical properties taken from Tekirdag region of Turkey on total mineral nitrogen and to determine the relations between ammonium sulfate transformation rate and soil properties. In the incubation test, 500 mg kg(-1) nitrogen in the form of ammonium sulfate solution has been treated to the soil and left to incubation for 28 days. The rate of transformation of ammonium sulfate in the soil samples taken on the 1(st) (D1), 7(th) (D7), 14(th) (D14) and 28(th) (D28) days of the incubation has been determined. A significant correlation has been determined between the nitrogen loss in soil samples and the lime, magnesium and potassium content of the soils. A positive correlation in the level of r=0.457** has been determined between ammonium sulfate transformation rate (ASTR) emerged in the 7(th) day of the test and the lime content of the soils. In the 28(th) day of the test, also a positive correlation in the level of r=0.338* has been determined between ammonium sulfate transformation rate (ASTR) and magnesium content of the soils while a negative correlation in the level of r=-0.360* has been identified between ammonium sulfate transformation rate (ASTR) and potassium content of the soils. It has not been detected any significant correlation in 1(st) and 14(th) days of the test.
