Abstract

In this study was conducted to investigate mineralization potentials of different land uses in the area of Genya Mountain-Artvin in 2011. For these purposes, soil samples were taken from surface 0-15 cm depth in young spruce stands, old spruce stands and spruce stand with Rhododendron understory, and adjacent grassland sites with similar parent material, slope and aspect. Samples were subjected to standard incubation technique in laboratory conditions (60% MSK and 25°C). Mineralization rate differed significantly among sites. Nitrification rates were significantly higher in grassland sites compared to other sites (174.61 N ha 21 day-1). There was a strong positive correlation between nitrate production rate and soil organic matter content (r2=0.70) and total N contents of soils (r2=0.80). There was also a negative correlation between nitrification rate and C/N content (r2=-0.48). Although soil organic matter contents of soils were relatively high, N mineralization rate wasn’t as high as expected. It was argued that the reason behind these lower rates was relatively high acidity in soils of the sites.

Özet

Bu çalışma 2011 yılında Artvin-Genya Dağı yöresinde farklı bitki örtüsü altındaki toprakların mineralleşme potansiyelini araştırmak için yapılmıştır. Bu maksatla aynı anakaya, aynı bakı grubunda (kuzey ve gölgeli bakı) ve ortalama olarak aynı eğim grubundaki, orman bitki örtüsünün ve çayır bitki örtüsünün bulunduğu alanlardan 0-15 cm toprak derinliğinden toprak örnekleri alınmış ve laboratuar koşullarında (%60 MSK ve 25°C) standart inkübasyon yöntemi kullanılarak azot mineralleşme potansiyeli araştırılmıştır. Orman bitki örtüsünün bulunduğu örnek alanlar genç ladin meşceresi (15-20 yaşında a3 çağı tam kapalı), yaşlı ladin meşceresi (100-120 yaşında d çağında d2 kapalıkta) ve altında ormangülü bulunan ladin (100-120 yaşında d çağında d2 kapalıkta) karışık meşceresinden seçilmiştir. Toplulukların topraklarında azot mineralleşme oranlarının farklı olduğu tespit edilmiştir. Nitrifikasyonun çayırlık alan topraklarında (174,61 kg N ha1 /21 gün-1) diğer alanlara göre daha yüksek olduğu, nitrat verimi ile organik madde (kg/ha) (r2= 0,70) ve toplam azot (kg/ha) (r2= 0,80) arasında kuvvetli pozitif ilişki bulunduğu belirlenmiştir. C/N oranı ile negatif korelasyon tespit edilmiştir (r2=-0,48). Araştırma alanlarında organik madde miktarının nispeten yüksek olmasına karşın azot mineralleşmesi çok yüksek tespit edilememiştir. Bunun nedeninin alanların topraklarında görülen asidik karakter olduğu sanılmaktadır.
