Root growth and nutrient uptake of Norway spruce container seedlings planted in mounded boreal forest soil
چکیده انگلیسی

The effects of mounding on root and shoot growth and nutrient uptake in 1- and 2-year-old Norway spruce (Picea abies (L.) Karst.) container seedlings were studied for 2 years after planting at a clear-cut forest site in Finland. Three different mounding treatments (spot mounding with and without mixing, and inverting) were compared with two unscarified treatments with or without a cardboard mulch. All of the mounding treatments that were used enhanced both the root and the shoot growth and also the nutrient uptake of the 1- and 2-year-old seedlings compared with the unscarified treatments. The foliar nitrogen concentration increased after planting, but the concentrations of other nutrients decreased. In particular, foliar boron decreased to a level of deficiency. The biomass growth of roots and shoots was greater in 2-year old than in 1-year-old seedlings. The results suggest that larger 2-year-old seedlings can utilize improved soil conditions after mounding slightly better than 1-year-old seedlings.
