Plant species compositions in the ecosystem and
soils developed under these species compositions cause nutrients to be fixed or
transport away from the site. The change of plant species compositions of
forest ecosystems in precipitation watersheds changes the quality of water
produced from these watershed. Especially, the fact that species such as Alder
with nitrogen fixation ability enter into plant species composition will be
effective on nutrient cycling. In this study, the effect of Alder on nitrogen transport
to surface waters and therefore the cation losses in the ecosystem in stands
where it is dominant was investigated. For this purpose, 36 surface water
samples from 3 sub-watersheds selected in Şimşirli stream watershed throughout
1 water year and 39 soil samples from 15 soil profiles opened in forest areas
were taken.
While water quality
parameters such as pH, EC, total nitrogen (TN), nitrate (NO3-N),
ammonium (NH4-N), Ca++, Mg++, K+
and Na+ were determined in surface waters, sand, silt, clay, pH, EC,
soil organic matter, total nitrogen and exchangeable cations (Ca++,
Mg++, K+ and Na+) were determined in soil
samples.
TN and NO3-N
concentrations in surface waters have increased along with the increase in the
rate of forest area in the lower watersheds. Increase of NO3-N
concentration in surface waters increased the basic cation (Ca++, Mg++
and K+) concentrations. This situation shows that leaching of
nitrate in the sub-watersheds increases the cation losses. Annual TN transport
in the sub-watersheds varied between 6.17 - 95.09 kg N Ha-1 and was
44.93 kg N Ha-1Year-1 on the average. Findings obtained
as a result of the study suggest that Alder might be an important species under
the control of the ecosystem and provide valuable information about the possible
eutrophication of Galyan-Atasu dam reservoir.

Ekosistemdeki bitki tür bileşimleri ve bu tür bileşimleri altında gelişen topraklar, besinlerin tutulmasına veya
ortamdan uzaklaşmasına sebep olurlar. Yağış havzalarındaki orman ekosistemlerinin bitki tür bileşimlerinin değişimi
bu havzalardan üretilen suyun kalitesini değiştirir. Özellikle azot bağlama yeteneğine sahip Kızılağaç gibi türlerin
bitki tür bileşimine girmesi besin döngüsü üzerinde etkili olacaktır. Bu çalışmada, hakim olduğu meşcerelerde Kızılağacın yüzey sularına azot taşınımı ve dolayısıyla ekosistemdeki katyon kayıplarına etkisi araştırılmıştır. Bu
amaçla, Şimşirli dere havzasında seçilen 3 alt havzadan 1 su yılı boyunca 36 adet yüzey suyu örneği ile orman
alanlarında açılan 15 toprak profilinden 39 adet toprak örneği alınmıştır. Yüzey sularında pH, EC, toplam azot (TN),
nitrat (NO3-N), amonyum (NH4N), Ca++, Mg++, K+ve Na+ gibi su kalite parametreleri, toprak örneklerinde kum, toz,
kil, pH, EC, organik madde, toplam azot ve değişebilir katyonlar (Ca++, Mg++, K+ ve Na+) belirlenmiştir. Alt
havzalardaki orman alanı oranının artmasıyla birlikte yüzey sularındaki TN ve NO3-N konsantrasyonları artmıştır.
Yüzey sularındaki NO3-N konsantrasyonunun artması bazik katyon (Ca++, Mg++ ve K+) konsantrasyonlarını
artırmıştır. Bu durum alt havzalardaki nitrat yıkanmasının katyon kayıplarını arttırdığını göstermektedir. Alt
havzalardaki yıllık TN taşınımı 6.17 - 95.09 kg N Ha-1 arasında değişmekte ve ortalama 44.93 kg N Ha-1Yıl-1'dır.
Çalışma sonucunda elde edilen bulgular, ekosistem kontrolünde Kızılağacın önemli bir tür olabileceği ve GalyanAtasu
barajı göletinin muhtemel ötrofikasyonu hakkında değerli bilgiler verebilir.
