Comparison of Density in Two Plantation Types of Atriplex canescens for Carbon Sequestration (Case study: Nodehak, Qazvin)

Growth of human population and increase in using of fossil fuel, cause to increase of greenhouse gases concentration such as atmospheric carbon dioxide over recent decades. In this study, the role of Atriplex canescens in carbon sequestration of experimental rangeland station of Nodehak in Qazvin province was investigated. The main treatment applied in a split plot design using the randomized completely blocks including two densities of 2×2 m and 4×4 m. In each treatment, four pruning heights consisting of without pruning (control treatment), completely pruning, pruning in 20 cm and 40 cm above ground. The carbon amount was measured for above and underground biomass and pruning heights, separately. The results showed that mean carbon amount in above and underground biomass per area unit in 2×2 m
