Abstract

The aim of this study was to determine high inorganic nitrogen concentration of eutrophic West Pond which supplies water to the Sakaryabasi Fish Culture and Research Station was originated whether from sediment or not. In the West Pond sediment, inorganic nitrogen (ammonium-nitrate) flux was estimated in the months (April, July, October, January) that represent the seasons. Negative ammonium and nitrate flux (retention) values were changed between 809.48 and 2069.52 μg.$m^ {-2}$.da$y^ {-1}$, from 2053.77 to 7718.10 μg. $m^ {-1}$.da$y^ {-1}$, respectively. The minimum and maximum inorganic nitrogen (ammonium-nitrate) flux values were estimated in July and January, respectively. During the decomposition or decay of macrophytes in autumn-winter period, the overlying water's high ammonium values (3.16 - 5.04 mg$L^ {-1}$) showed that macrophytes play an important role in preventing or suppressing the release of mineralized dissolved nitrogen from sediment to the overlying water. The other possible factors on the continuity of the pond eutrophication and the hindered nitrogen flux were no significant differerence at water temperature (18.53 - 21.28°C), no occurrence of anoxic condition in the pond (dissolved oxygen; 5.85 - 7.28 mg$L^ {-1}$) and not a suitable range of pH (7.09 - 7.62) for the nitrification process.

Özet

Bu araştırma ile Sakaryabaşı (Çifteler-Eskişehir) Balık Üretim ve Araştırma İstasyonu'na su sağlayan ötrofik Batı Göleti suyundaki yüksek inorganik azot düzeyinin sediment kaynaklı olup olmadığının belirlenmesi amaçlanmıştır. Gölet sedimentinde, örneklemenin yapıldığı mevsimleri temsil eden aylarda (Nisan, Temmuz, Ekim, Ocak) negatif yönde inorganik azot (amonyum-nitrat) salınımı (tutulumu) tahmin edilmiş; amonyum ve nitrat tutulum değerleri sırasıyla, 809,48 - 2069,52 μg/$m^ 2$.gün ve 2053,77 - 7718,10 μg/$m^ 2$.gün arasında değişmiştir. En düşük inorganik azot (amonyum-nitrat) tutulum değerleri temmuz ayında, en yüksek değerler ise ocak ayında tespit edilmiştir. Makrofitlerin çürüdüğü veya öldüğü sonbahar kış döneminde, sediment üstü suda amonyumun yüksek bulunması (3,16 - 5,04 mg/L) sucul bitkilerin, sedimentten sediment üstü suya mineralize olmuş çözünmüş inorganik azotun salınımını baskılamada veya önlemede önemli rol oynadığını göstermiştir. Gölet ötrofikasyonun sürekliliğinde ve sedimentten azot salınımının engellenmesinde; su sıcaklığının çok değişim göstermemesi (18,53 - 21,28°C), gölette anoksik koşulların ortaya çıkmaması (çözünmüş oksijen; 5,85 - 7,28 mg/L) ve pH aralığının (7,09 - 7,62) nitrifikasyon süreci için uygun olmasının da olası unsurlar olduğu saptanmıştır.
