Öz

Farklı arazi kullanımı altındaki toprakların kontrol konusu, sürekli donma ve iki kez donma uygulamaları altında bazı fiziksel özelliklerindeki değişim bu araştırma kapsamında ele alınmıştır. Aynı toprak serisinde yer alan kumlukillitın bünyeli orman, mera ve tarım arazilerinden alınan yüzey (0-20 cm) toprak örnekleri kontrol konusu, sürekli donma ve iki kez donma uygulamalarına maruz bırakılmıştır. Toprakların makro ve mikro agregat yüzdeleri ile dispersiyon oranı değerleri, araştırma uygulamalarına bağlı olarak istatistiksel önemde bir değişim göstermemiştir. Mera topraklarında, sürekli donma uygulamasında, makro agregat stabilitesi ve agregat stabilitesi değerleri artmıştır.

Anahtar Kelimeler

Agregat stabilitesi, donma-çözülme, dispersiyon oranı, farklı arazi kullanımı
