Abstract

The nitrogen mineralization rates in the soils of three coniferous forest communities (Pinus nigra subsp pallasiana, Abies cilicica subsp cilicica, Cedrus libani) in the middle Taurus Mountains (Turkey) were investigated. N mineralization was determined by the standard incubation method under laboratory conditions at 20ºC and 60 %WHC. Mineral nitrogen ($NH_4^+-N ve NO_3- _-N$) was analyzed in the beginning, $21^ {st}$ and $63^ {rd}$ days of incubation by micro-distillation. Net mineral nitrogen accumulations were calculated for the 63-days ($mg N_{min} $ / 100 g dry-soil / 63-days). Needle-leaf forest communities were crossexamined based on their mineral nitrogen and soil parameters. The relationships between the mineral nitrogen production and soil factors were analyzed by a simple correlation test. Mineral nitrogen production in the soils of these communities is strongly related to the total nitrogen rate. The highest total nitrogen mineralization rates were determined in the soils of the Abies cilicica community. The nitrogen mineralization in the soils of three closely related needle-leaf forest communities in the Eastern Mediterranean phyto-geography region were found to be different.

Özet

Orta Toros dağlarından üç iğne yapraklıorman ağacı(Pinus nigra subsp. pallasiana, Abies cilicica subsp cilicica, Cedrus libani) topluğunun topraklarında azot mineralleşme oranlarıaraştırılmıştır. N mineralleşmesi 20ºC ve %60 MSK laboratuar koşullarında standart inkübasyon yöntemiyle belirlenmiştir. Mineral azot ($NH_4^+-N ve NO_3- _-N$) inkübasyonun başlangıcı, 21ci günü ve 63cü gününde mikro-destilasyon yöntemiyle tayinF edilmiþtir. Net mineral azot birikimleri 63 gün için hesaplanmıştır ($mg N_{min} $/ 100 g kuru toprak / 63 gün). Ýðne yapraklıorman ağacıtopluluklarımineral azot ve toprak parametrelerine göre karşılaştırılmış, mineral azot üretimi ile toprak etmenleri arasındaki ilişkiler basit korelasyon testi ile analiz edilmiştir. Araştırılan toplulukların topraklarında mineral azot üretiminin toplam azot oranıyla kuvvetli ilişkili olduðu saptanmış, en yüksek toplam azot ve mineralleşme oranları Abies cilicica topluluğunun toprağında belirlenmiştir. Doğu Akdeniz bitki coğrafyası bölgesindeki birbiriyle ilişkili üç iğne yapraklıorman aðacıtopluluğunun toprağında azot mineralleşmesinin farklıolduğu belirlenmiştir.
