Abstract :This study was carried out to determine the alkaline phosphatase insert ignore into journalissuearticles values(ALP); enzyme activity and the effects of some soil properties on ALP enzyme activity in the soils of agricultural production areas in Gaziantep province. In the study, soil samples were taken from 24 dry farming plots, 12 irrigated farming plots and 9 fallow farming plots. In addition to ALP enzyme activity in soil samples, soil pH, EC, SOM, lime, soil texture, phosphorus insert ignore into journalissuearticles values(P); and potassium insert ignore into journalissuearticles values(K); contents were determined. As a result of the study, it was determined that the soils were slightly alkaline, unsalted and very calcareous. These soils, which are deficient in organic matter insert ignore into journalissuearticles values(SOM); content, were found to be rich in P and K. However, the mean ALP enzyme activity was found to be 334.12 ± 123.83 µg p-NP.gr top-1.s. -one. As a result, the order of ALP enzyme activity according to land use was determined as fallow > irrigated agriculture > dry agriculture. There was no significant relationship between ALP enzyme activity and general soil properties. In this study, it was concluded that it is possible to increase the SOM content of soils only by using appropriate organic fertilizers.
