Özet:

 Background and aims There are different approaches for genetic and quantitative soil classification, which can be defined as evaluating soils according to their formation and development processes. In Türkiye, the soil taxonomy system developed by the USDA was used for classifying agricultural soils for many years. For forest soils, the Central European Soil Classification System was used. Until today, the World Reference Base for Soil Resources WRB classification system was used in a few studies in Türkiye and almost all of these have been done on agricultural lands. Due to the lack of surveys according to WRB on forest soils, the Atatürk Arboretum Management Unit, a natural extension of Belgrade Forest Istanbul, is selected as the research area. Methods Soil samples are taken from 48 plots with a soil probe on a 250x250 m systematic grid, and the locations where different horizon developments exist are determined. The plots with common horizon developments are grouped, thus 13 representative soil profile pits were excavated for further evaluation. Results As a result of the study, these soils are classified in line with the WRB guidelines, and 4 different Reference Soil Groups are determined with their prefixes and suffixes. The identified soil groups in the Atatürk Arboretum Management Unit are Stagnosol, Cambisol, Alisol, and Acrisol. Conclusions The lack of expertise in forest soil classification with WRB is visible and this shortage needs to be overcome through scientific studies and training. It is thought that this study constitutes a suitable example for soil classification practices to be carried out in the future using the WRB classification system in forests.

 Giriş ve Hedefler Toprakların oluşum ve gelişim süreçlerine göre değerlendirilmesi olarak tanımlanabilen toprak sınıflandırmasında farklı yaklaşımlar bulunmaktadır. Uzun yıllardan bu yana Türkiyede tarım topraklarının sınıflandırmasında USDA tarafından geliştirilen Toprak Taksonomisi, orman topraklarının sınıflandırmasında ise Orta Avrupa toprak sınıflandırma sistemi kullanılmaktadır. Bunlara nazaran yeni bir sistem olan Toprak Kaynakları İçin Dünya Referans Temeli DRT isimli sistem ise ülkemizde oldukça az çalışmada kullanılmış ve bu çalışmaların neredeyse tamamı tarım topraklarında gerçekleştirilmiştir. Bu sınıflandırma sisteminin orman topraklarında uygulanması konusundaki eksiklik sebebi ile Belgrad Ormanının İstanbul doğal bir uzantısı olan Atatürk Arboretumu Şefliği araştırma alanı olarak seçilmiş ve DRT sınıflandırma sistemine göre Referans Toprak Gruplarının ayrıntılı bir biçimde belirlenmesi amaçlanmıştır. Yöntemler Yapılan çalışmada öncelikle 250x 250 mlik sistematik bir ağ üzerinde toprak sondası ile 48 noktadan örnekler alınmış ve farklı horizon gelişimlerinin olduğu yerler belirlenmiştir. Ortak horizon gelişimlerinin olduğu noktalar gruplandırılmış ve ardından bu grupları temsilen ait 13 noktada toprak profil çukuru kazılarak rapor ve örneklemeler yapılmıştır. Bulgular Çalışmanın sonucunda DRT el kitabı doğrultusunda bu topraklar sınıflandırılarak 4 adet farklı Referans Toprak Grubu, ön ek ve son ekleri ile belirlenmiştir. Atatürk Arboretumu Şefliğinde gözlemlenen bu gruplar rastlanma sırasına göre Stagnosol, Cambisol, Alisol ve Acrisoldür. Sonuçlar Özellikle ormancılık disiplininde DRT sınıflandırma sistemi ile referans toprak gruplarını belirleyebilecek uzman eksikliği bulunmaktadır. Bu uzman eksikliğinin yapılacak bilimsel çalışmalarla ve eğitimler ile arttırılması gerekmektedir. Çalışmanın, orman topraklarında DRT sınıflandırma sisteminin kullanılacağı çalışmalara uygun bir örnek teşkil ettiği düşünülmektedir.
