Summary
Çevresel faktörlerden sıcaklık ve nem toprakta organik karbonu ayrışmasını kontrol eden önemli faktörlerdir. Farklı kullanımlar altındaki toprakların sıcaklık ve neme karşı duyarlılıkları farklılık gösterebilir. Bu çalışmanın amacı farklı kullanımlar altındaki (tarım, mera ve orman) toprakların farklı sıcaklık (20 oC and 35 oC) ve nem koşullarında (tarla kapasitesi (TK) % 30 ve % 60) mineralize C içeriğindeki değişimin belirlenmesi. Bu çalışma Tokat ili Almus ilçesindeki tarım, orman ve mera arazilerinde yürütülmüştür. Çalışmada toprak örnekleri 0-5, 5-15 ve 15-30 cm derinliklerden el burgusu yardımıyla alınmıştır. Alınan örnekler analize hazırlandıktan sonra toprakların tekstür, pH, kireç, organik madde, toplam C, organik C, mikrobiyal biyokütle C ve mineralize C değerleri belirlenmiştir. Mineralize C miktarı tarla kapasitesi % 30 ve % 60 nem düzeyine getirilmiş örneklerin 20 oC ve 30 oC sıcaklıklarda inkübasyonuyla belirlenmiştir. Topraklar genel olarak killi tekstür sınıfında bulunmuştur. Organik karbon arazi kullanımına göre en yüksek orman toprağında bulunmuştur. Mikrobiyal biyokütle C arazi kullanımına bağlı olarak önemli değişiklik göstermiştir. Farklı kullanımlar altındaki toprakların 20 °C sıcaklık ve iki farklı nem koşulunda inkübasyonunda kullanımlar arasında fark yalnızca TK % 60 nem düzeyinde görülmüştür. Bezer durum 35 oC sıcaklıkta da görülmüştür. Yüksek nem koşullarında kullanımlar arasında önemli farklılık oluşmuştur. Nem miktarındaki artış tarım toprağında mineralize C miktarını önemli düzeyde artırırken, orman toprağında sıcaklıktaki artış önemli olmuştur. Bu durum orman toprağında mineralize C miktarının sıcaklığa daha duyarlı olduğunu ortaya koyarken, tarım toprağının nem miktarındaki artışa daha duyarlı olduğunu ortaya koymaktadır.

Abstract
Temperature and humidity are the important environmental factors that control the decomposition of organic carbon in the soil. The sensitivity of the soils to temperature and moisture may vary. The aim of this study is to determine the change in mineralized C content of different soils (agriculture, pasture and forest) at different temperature (20 oC and 35 oC) and humidity conditions (30% and 60% of field capacity). This study was carried out in agriculture, forest and pasture lands in Almus district of Tokat province. In the study, soil samples were taken from 0-5, 5-15 and 15-30 cm depths by hand probe. Particle distribution, pH, lime, organic matter, total C, organic C, microbial biomass C and mineralize C were determined in the samples. Mineralize C content was determined by incubation of 30% and 60% of field capacity at 20 oC and 30 oC. Soils were generally classified as clay texture. The highest organic C was found in forest soil. Microbial biomass C showed significant change depending on land use. The difference between the land uses at 20 °C incubation was only observed at 60% of field capacity. The similar trend was also seen at 35 °C temperature. Significant differences have been observed between uses at high humidity conditions. While the increase in the amount of moisture significantly increased the amount of mineralize C in agricultural soil, the increase in temperature in forest soil was significant. This result indicates that the amount of mineralize C in the forest soil is more sensitive to temperature, while agricultural soil is more sensitive to the increase in moisture content.
