The subject of this study is to determine the below-ground plant biomass and annual below-ground net primary production of lowland meadows in the Central Black Sea region. This study calculated the annual average amount of below-ground plant biomass, its seasonal distribution, annual primary production, and turnover values in the ungrazed and grazed meadow stands. Below-ground plant biomass, below-ground net primary production, and turnover of grazed stands were higher than in ungrazed stands. This turnover value shows that root biomass is renewed faster in grazed areas. Grazing, annual rainfall, and soil characteristics may have led to these different results.

Türkiye'nin Orta Karadeniz Bölgesi Ova Çayır Vejetasyonunda Hayvan Otlatılan Bir Alan ve Hayvan Otlatılmayan Korunmuş Bir Komşu Arazinin Yeraltı Biyokütlesi ve Verimliliği

Öz

Bu çalışmanın konusu, Orta Karadeniz bölgesindeki ova çayırlarının yer altı bitki biyokütlesini ve yıllık yer altı net birincil üretimini belirlemektir. Bu çalışmada, hayvan otlatılmayan ve otlatılan çayır topluluklarında yıllık ortalama yer altı bitki biyokütle miktarı ve mevsimsel dağılımı, yıllık birincil üretim ve devir hızı (turnover) değerleri hesaplanmıştır. Hayvan otlatılan meşcerelerin yer altı bitki biyokütlesi, yer altı net birincil üretimi ve devir hızı, hayvan otlatılmamış alanlara göre daha yüksektir. Bu devir hızı değeri hayvan otlatılan alanlarda kök biyokütlesinin daha hızlı yenilendiğini göstermektedir. Otlatma süresi/miktarı, yıllık yağış miktarı ve toprak özellikleri bu farklı sonuçlara yol açmış olabilir.
