Abstract:

 As a reservoir of organic carbon, soil is under threat due to various factors. Along with soil degradation and erosion, carbon stocks are also decreasing. This study was conducted to reveal the changes in organic carbon content under different land use types. The research was carried out within the Alaçam district in Samsun province. 32 soil samples were collected during fieldwork, half obtained from agricultural lands and the other half from pasture areas. The collected samples were subjected to preliminary processing and then analyzed for specific physical and chemical properties such as texture and organic matter. The results were geostatistically analyzed and mapped using ArcGIS 10.2.2 software. Descriptive statistical analyses were performed using the SPSS 17.0 package. According to the results, although no statistically significant difference was found, organic carbon values in agricultural lands were lower than in pasture areas. It was determined that approximately 8 of the districts land area exhibited low carbon values ranging from 1.09 to 1.92 tonsha. In the southern parts, where pastures and forested areas are more concentrated, carbon content reaches 3.70 tonsha. The study results indicate that the low carbon content in agricultural lands suggests that the agricultural land-use pattern and practices reduce soil carbon stocks.

 Organik karbon deposu olan toprak, çeşitli sebeplerle tehdit altındadır. Arazi bozulumu ve erozyonla zarar gören toprakla birlikte, karbon depoları da azalmaktadır. Bu araştırma farklı arazi kullanımları altında organik karbon miktarının değişimini ortaya koymak amacıyla gerçekleştirilmiştir. Araştırma Samsun ili, Alaçam ilçesi sınırlarında gerçekleştirilmiştir. Arazi çalışmaları ile 32 adet toprak örneği alınmıştır. Örneklerin yarısı tarım alanlarından yarısı ise mera arazilerinden alınmıştır. Toplanan örnekler önişlemlerle analize hazır hale getirilmiş, toprak organik madde gibi fiziksel ve kimyasal bazı analizlere tabi tutulmuşlardır. Sonuçlar ArcGİS 10.2.2 programı ile jeoistatistik yapılarak uygun yöntemle haritalandırılmıştır. Tanımsal istatistikler ise SPSS 17.0 paket programı ile gerçekleştirilmiştir. Elde edilen sonuçlara göre istatistiksel olarak anlamlı fark bulunmamakla birlikte tarım alanlarında organik karbonun mera arazilerine göre daha düşük değerler gösterdiği tespit edilmiştir. İlçe arazilerinin yaklaşık 8inde karbon değerlerinin 1.09-1.92 tonha gibi düşük değerler gösterdiği belirlenmiştir. Mera arazilerine ve orman alanlarının daha fazla bulunduğu güney kesimlerde ise karbon içeriği 3.70 tonh kadar çıkmaktadır. Araştırma sonucuna göre, tarım alanlarında karbon miktarının düşük olması sahanın tarımsal arazi deseni ve arazi kullanımının toprak karbonunu azalttığını göstermektedir.
