Bu araştırma 2010 Ocak ayında İstanbul'un kuzeyinde yer alan Çatalca - Karacaköy Orman
İşletme Şefliği idaresindeki alanlarda yürütülmüştür. Çalışma kapsamında ince ağaçlık çağında bulunan
(1.30 m Ø ≈ 20 cm) meşe ormanından (Quercus frainetto Ten., Q. cerris L., Q. robur L. ve Q. petraea
(Mattuschka) Lieblein)), çalı (Cistus spp.), yeni terk edilmiş tarla (≈5 yıl YTT) ve eski terk edilmiş tarla
(≈20 yıl) (ETT) alanlarından alınan örneklerin deneylik koşullarında bekletilmesi ile net azot
mineralleşmesi miktarı belirlenmeye çalışılmıştır. Araziden alınan toprak örnekleri deneylik koşullarında
(21oC ve ağırlıkça %60 nemlendirilmiş) 29 gün bekletilerek net azot mineralleşme miktarları
belirlenmiştir. Elde edilen sonuçlara göre; bekletme öncesinde amonyum-N miktarları ETT, çalı ve orman
alanlarında YTT alanlarından p
