Abstract:

 In forested wetlands, which constitute 60 of wetlands and are responsible for 35 of the earths soil organic carbon stock, macro and micro nutrient stocks are also important in terms of the development and sustainability of these ecosystems. Aim of the study was to determine the carbon, macro and micro-nutrient concentrations and stocks in the litter and soil of ash tree stands at the floodplain and terrestrial sites in Bursa Karacabey. Litter C, N, P, K, Ca, Mg and S stocks in the floodplain were 1522, 52, 62, 123, 915, 211 and 110 kgha respectively, while except for N, those values were significantly lower in the terrestrial as 829, 61, 51, 88, 538, 129 and 61 kgha, respectively. Litter micronutrient stocks were also higher in the floodplain sites. Soil C and macronutrient stocks were also higher in the floodplain. While soil C, N, P, K, Ca, Mg and S stocks in the floodplain were 246, 27, 6, 85, 104, 188 and 6 tonha respectively, these values were found as 233, 24, 5, 77, 177 and 6 tonha in the terrestrial. Soil micronutrient stocks were also higher in the floodplain sites. In addition, it was noted that litter carbon and macro and micro nutrient stocks decreased with the stand age, while soil stocks increased. It was also seen that soil C and N were mainly stored in the topsoil 0-30 cm 71 and 61, respectively, whereas the stocks of other soil macro and micronutrients in the subsoil 30-100 cm were higher compared to the topsoil. The results has provided numerical information whşch are useful for understanding and modeling the carbon and nutrient cycling and stocks of forested wetland ecosystems, which have an important role in reducing climate change due to their capacity to capture and store atmospheric CO2 and N.

 Sulak alanların 60ını oluşturan ve yeryüzü toprak organik karbon stokunun 35inden sorumlu olan subasar orman ekosistemlerinde, makro ve mikro besin stokları bu ekosistemlerin gelişmesi ve sürdürülebilirliği açısından önem kazanmaktadır. Çalışmada, Bursa Karacabey subasar ormanlarında, subasar ve karasal ortamdaki dişbudak meşcerelerinin, ölü örtü ve topraklarının C yoğunluğu, makro ve mikro besin yoğunluğunu ve stoklarını toprak derinlik kademeleri de dikkate alarak belirlemektir. Ölü örtü C, N, P, K, Ca, Mg ve S stoku sırasıyla 1522, 52, 62, 123, 915, 211 ve 110 kgha olarak subasar ortamda belirlenirken, karasal ortamda bu değerler N hariç önemli derecede daha düşük olup, sırasıyla 829, 61, 51, 88, 538, 129 ve 61 kgha olarak belirlenmiştir. Ölü örtü mikro besin stoklarıda subasar ortamda karasal ortama göre daha yüksek bulunmuştur. Toprak C ve makro besin stoklarıda N dahil subasar ortamda daha yüksek bulunmuştur. Topraktaki C, N, P, K, Ca, Mg ve S stoku sırasıyla 246, 27, 6, 85, 104, 188 ve 6 tonha olarak subasar ortamda belirlenirken, karasal ortamda bu değerler sırasıyla 233, 24, 5, 77, 177 ve 6 tonha olarak belirlenmiştir. Toprak mikro besin Fe, Mn, Na, Cu, Zn, Cl, Ni ve Co stoklarıda subasar ortamda karasal ortama göre daha yüksek bulunmuştur. Ek olarak, ölü örtü karbon ile makro ve mikro besin stoklarının meşcere yaşına bağlı olarak azaldığı, topraktaki stoklarının ise artış gösterdiği tespit edilmiştir. C ve Nun en fazla üst topraklarda 0-30 cm stoklandığı sırasıyla 71 ve 61, diğer makro ve mikro besinlerin ise alt topraklardaki 30-100 cm stoklarının, üst topraklardan daha fazla olduğu belirlenmiştir. Sonuçlar, atmosferik karbondioksiti ve azotu tutma ve depolama kapasiteleri nedeniyle iklim değişikliğinin azaltılmasında önemli bir role sahip, subasar orman ekosistemlerinin karbon ve besin döngülerini ve stoklarını anlamaya ve modellemeye faydalı sayısal bilgiler sağlaması açısından önemlidir.
