Investigation of some microbiological properties of Gaziantep / Araban agricultural soils

The aim of this study is to investigate some microbiological properties of Gaziantep/Araban agricultural soils. Microbial biomass is an important element that increases soil fertility with the removal of nutrients from soil by plants. In this study, the contents of organic nitrogen, organic carbon, microbial carbon, microbial nitrogen, phospholipid fatty acids and alkaline phosphatase enzyme activities (PLFA, Corg-Norg, Cmic, Nmic) of agricultural soils of Gaziantep/Araban were determined. Four stations were identified in the study area. The soils of the study area showed sandy silt, light sandy shore, light clay, and silt textured with alkaline properties. Also, the amount of organic matter was found to be between 0.82 and 4.50%. alkaline phosphatase enzyme activity was found to be between 285.49-442,14 μg/g, microbial Nitrogen, and microbial Carbon contents were found to be between 199,92-225,95 and 16,60-29,85 respectively. Sixteen different fatty acids were detected in agricultural soil samples taken from Araban, they were as follows: 14:0, 15:0, 16:0, 17:0, 18:0, a15:0, i15:0, i16:0, i17:0, cy17:0, cy19:0, 16:1⍵7t, 18:1⍵9c, 18:1⍵9t, 18:2⍵6, 20:0. As a result of this study, the microbiological characteristics of Araban agricultural soils have been determined. As a result, it is necessary to increase the productivity and quality of the region by making more informed agricultural practices.
