Özet:

 Soil respiration is an important source of carbon dioxide CO2 released into the atmosphere and is an important ecosystem process in terms of global warming. Forestry practices can significantly affect this process. In this study; the effects of different thinning intensities and seasons on microbial biomass carbon C, basal respiration and soil respiration were investigated in the oriental beech Fagus orientalis L. plantation area in Trabzon. For this purpose, a total of nine plots were established with three replications at two different thinning intensities 25 and 40 and control. Measurements made for one year. As a result of the study, the mean soil microbial biomass C contents; It was found to be 469.57 gg in the 25 thinning plots, 478.73 gg in the control plots and 541.06 gg in the 40 thinning plots. ANOVA results show that soil microbial biomass C content in 40 thinning plots was significantly higher than control and 25 thinning plots. Microbial biomass C contents were significantly higher in summer than in the other seasons. There was no significant difference between the control and the soils of thinned plots in terms of microbial respiration and soil respiration values. On the other hand, basal respiration and soil respiration showed significant changes according to the seasons. Since there was no water deficit in the study area, it was thought that the changes were determined by soil temperature rather than soil moisture limitation. In terms of carbon management, 25 thinning intensity was not at a level to make a significant difference in carbon emissions from the soil. When we look at the CO2 release in the 40 thinning, it has been determined that the intervention promoted microbial biomass positively, but did not significantly change the CO2 release in the soil. Therefore, it was concluded that these thinning intensities in beech plantations in this region did not cause significant carbon emissions and were beneficial for soil health as they enhanced microbial biomass.

 Toprak solunumu atmosfere verilen karbondioksitin CO2 önemli bir kaynağı olup küresel ısınma bakımından önemli bir ekosistem sürecidir. Yapılan ormancılık uygulamaları bu süreci önemli derecede etkileyebilmektedir. Bu çalışmada; Trabzonda Doğu kayını Fagus orientalis L. ağaçlandırma alanında farklı aralama derecelerinin ve mevsimlerin, mikrobiyal biyokütle karbon, bazal solunum ve toprak solunumuna etkileri araştırılmıştır. Bu amaçla iki farklı aralama şiddetinde 25 ve 40 ve kontrolde, üç tekerrür ile toplam dokuz deneme alanı oluşturulmuştur. Ölçümlere bir yıl boyunca devam edilmiştir. Sonuçlar tek yönlü varyans analizi ANOVA ile değerlendirilmiştir. Çalışma sonucunda ortalama toprak mikrobiyal biyokütle C içerikleri; 25 aralama yapılan parselde 469,57 gg, kontrol parselinde 478,73 gg ve 40 aralama yapılan parselde 541,06 gg olarak bulunmuştur. ANOVA sonuçları 40 aralama parsellerindeki mikrobiyal biyokütle C içeriklerinin kontrol ve 25 aralama yapılan parsellerden anlamlı oranda yüksek olduğunu göstermektedir. Mikrobiyal biyokütle C içerikleri yaz mevsiminde diğer mevsimlerden anlamlı oranda yüksektir. Kontrol ile aralama yapılan topraklar arasında bazal solunum ve toprak solunumu değerleri bakımından anlamlı bir fark belirlenememiştir. Buna karşılık bazal solunum ve toprak solunumu mevsimlere göre anlamlı oranda değişim göstermiştir. Çalışma alanında su açığı olmadığı için değişimlerin nem yetersizliğinden çok, sıcaklık tarafından belirlendiği düşünülmektedir. Yapılan 25 aralama şiddeti karbon yönetimi açısından bakıldığında topraktaki karbon salımında anlamlı fark yaratacak düzeyde değildir. 40 oranında yapılan aralamada da CO2 salınımı yönünden yapılan müdahalenin mikrobiyal biyokütleyi olumlu yönde teşvik ettiği, topraktaki CO2 salımını ise anlamlı düzeyde değiştirmediği tespit edilmiştir. Dolayısıyla bu yörede kayın plantasyonlarında yapılan bu aralama çalışmalarının önemli ölçüde karbon salımına neden olmadığı, mikrobiyal biyoması teşvik ettiği için toprak sağlığı açısından yararlı olabileceği sonucuna varılmıştır.
