The change of the
physico-chemical properties of soils caused by fires can be considered as one
of the leading factor for land degradation, especially in a Mediterranean type
ecosystems. The study sites is located in a Mediterranean ecosystem dominated
by Pinus brutia southern Marmara, Turkey (Akbas, Canakkale). Soil samples were
collected from the surface layer (0-5 cm depth) of the burnt and unburnt areas,
1 month, 1, 2 and 3 years after the wildfire. Texture, aggregate stability, pH,
electrical conductivity (EC), lime (CaCO3), organic matter and available
element contents (P, K, Ca, and Mg) were analyzed in the soil samples.
Differences were not observed in clay, silt and sand contents of burnt and
unburnt soils in research site. Although aggregate stability and pH contents of
burnt soils were higher than unburnt soils in Akbas, no statistically
significant difference was found. EC, organic matter, P, K, Ca, and Mg contents
of burnt soils compared to unburnt soils increased. CaCO3 contents of unburnt
sections of Akbas were respectively 1.65 times higher than burnt sections

Çanakkale (Eceabat, Akbaş Şehitliği) orman yangınıyla bazı fiziksel ve kimyasal toprak özelliklerinin zamansal değişiminin belirlenmesi

Öz

Özellikle
Akdeniz tipi ekosistemlerde yangınların neden olduğu toprakların
fiziko-kimyasal özelliklerinin değişmesi arazi bozulmasına neden olan
faktörlerden biri olarak düşünülmektedir. Araştırma alanı Güney Marmara
Bölgesi’ndeki Çanakkale’ nin Akbaş Şehitliği’nde Pinus bruita’nın baskın olduğu
Akdeniz ekosisteminde yer almaktadır. 
Yangından 1 ay, 1 yıl, 2 yıl ve 3 yıl sonra yanan ve yanmayan alanlardan
0-5 cm derinlikten toprak örnekleri alınmıştır. Toprak örneklerinde bünye,
agregat stabilitesi, pH, elektriksel iletkenlik (EC), kireç (CaCO3), organik
madde ve yarayışlı element (P, K, Ca ve Mg) analizleri yapılmıştır. Araştırma
alanındaki yanan ve yanmayan toprakların kil, silt, kum yüzdeleri farklılık
göstermemiştir. Akbaş’taki orman yangınında toprakların agregat stabilitesi ve
pH’sı yanmayan alana göre yanan alanda daha yüksek olmasına rağmen istatistik
olarak önemli fark bulunmamıştır. Çalışma alanında yanmayan topraklara göre
yanan toprakların EC, organik madde, P, K, Ca ve Mg içerikleri artış göstermiştir.
Akbaş’taki yanmayan alanlarda CaCO3 1.65 kat daha fazla saptanmıştır.
