Assessment of some soil properties and organic carbon and total nitrogen storage capacities of natural and plantation black pine forests in semi-arid regions

Abstract

This research was carried out to investigate some soil properties and carbon and nitrogen storage status in natural and plantation black pine forest establishments in Çankırı province, Eldivan District, Eldivan Mountain. Sample areas (400 m2) were taken from natural and artificial forest areas to determine stand parameters, soil and litter properties. Based on genetic horizon in soil pits and topsoil (0 - 15 cm) sampling in 50x50 m grid system was done in study areas. The physical and chemical properties of soils have been determined. The lowest (0.46 g.cm-3) bulk density has been measured in natural forest topsoil. The organic carbon amounts of the upper soils in hectare are between 30.36 – 66.73 t.ha-1in the natural forest and 20.33 – 53.14 t.ha-1 in the plantation forest. Total nitrogen amounts are between 3.53-6.78 ve 2.05-5.29 ton.ha-1 respectively. The average carbon amount of natural forest top soils in hectare is 47.3 t.ha-1, and 32.2 t.ha-1 of plantation forests, total nitrogen 4.9 ve 3.2 t.ha-1 respectively. According to the results of this research, plantation and natural forest soils showed similar characteristics. This situation has shown that afforestation is successful.
