Nitrogen, phosphorus and carbon dynamics of hornbeam leaf litter (Case study: District one, Shastkalate forest, Gorgan)
The aim of this study was investigation of Carbon, Nitrogen and Phosphorus dynamics in Carpinus betulus L. leaf litter in organic layer of a broad-leaved mixed forest in Gorgan. Fresh litters were collected from five plots in district one, Shastkalate forest and were placed into some litterbags with...
