N mineralization potential under different land uses in Tutunculer in Artvin,Turkey

This study was conducted to investigate mineralization potensial of different land uses in the area of Tutunculer in Artvin in 2011. For this purposes, soil samples were taken from surface 0-15 cm depth in young scothpine stands, scothpine and spruce stand and adjacent grassland sites with similar parent material, slope and aspect. Samples were subjected to standard incubition technique in labratory conditions (60% MSK and 25 0C). Mineralization rate different significantly among sites. Nitrification rate higher in grassland sites compared to other sides (149.46 N kg/ha 63 day-1)
