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

The subject of this study is to determine the belowground plant biomass and annual belowground net primary production of lowland meadows in the Central Black Sea region. In this study, the annual average amount of belowground plant biomass, its seasonal distribution, annual primary production, and turnover values in the ungrazed and grazed meadow stands were calculated. Belowground plant biomass, belowground 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.
