Field performance of outplanted Norway spruce: effects of organic matter amendments and site preparation
Norway spruce (Piceaabies (L.) Karst.) seedling survival and growth response to site preparation methods involving different utilization of humus (forest floor material from the F- and H-layers) and chipped slash were studied on a recently clear-felled spruce site in northern Sweden. Five mounding t...
