INVESTIGATION OF TOTAL CARBON AND NITROGEN CONTENT OF GAZİANTEP AGRICULTURAL SOILS

Abstract

Microbial biomass is a very important feature for plants to take nutrients from the soil and increase their yield. In addition to soil pollution by using unnecessary chemical fertilizers, groundwater is also polluted and reappears as an environmental problem. Microbial biomass, which is very effective in preventing soil erosion, is significantly damaged by these chemical fertilizers. In this study, the Cmic and Nmic contents of agricultural soils in Gaziantep province were determined and the relationship between microbial carbon and nitrogen contents and organic carbon and organic nitrogen contents in the samples was determined. Approximately 40 soil samples were taken from the agricultural areas where the study was conducted and some physical and chemical properties of the soil as well as Cmic and Nmic contents, which play a role as bio-indicators in soil health and fertility, were determined. As a result of the analyzes, it was determined that the microbial carbon and microbial nitrogen contents of the soils were not sufficient and organic fertilization was urgently needed. In addition, it was determined that there is a statistical relationship between the microbial carbon and nitrogen contents and the organic carbon and nitrogen contents of the soils.
