“…3 and 4). Previous studies have also shown the positive effect of nutrient loading on growth in rich soils, but usually to a lesser degree than in poor soils (Timmer and Munson 1991, Idris et al 2004, Rikala et al 2004). This suggests that seedlings in rich soils are less dependent on the internal N stores than seedlings in poor soils Timmer 2001, 2003).…”

“…Instead, the mass of roots inside the root plug was greater in seedlings with the highest NLT than in the other NLTs. It may be the case that, despite autumn rains, a higher amount of nutrients, which have been dissolved with some delay in the root plugs of high NLT (Idris et al 2004), may have reduced the need of the roots to grow out of the root plugs. Nevertheless, NLT had only a small effect on the root growth.…”

In recent years increased fertilization provided to tree seedlings in the nursery in the previous autumn has been introduced in order to promote good outplanting performance. In this paper this nutrient loading has been studied in order to determine how the increased seedling nutrient status with unaffected seedling size affects both the growth and the nutrient concentration, content and uptake of two-year-old Norway spruce container seedlings (Picea abies (L.) Karsten) after outplanting. Seedling development was monitored for three years at two contrasting soil fertility levels on a sandy test field in two planting years and on one natural forest outplanting site in central Finland. Nutrient loading was shown to increase shoot and root growth in a poor fertility soil during the first growing season after planting, while, after the first growing season, nutrient loading was not found to affect seedling performance. However, although nutrient loading cannot compensate for the availability of nutrients to the seedlings from the soil, it may provide an additional input for fast plantation establishment on poorer sites during the first crucial growing season after outplanting.

“…For boreal sites with thick humus and dominated by ericaceous shrubs, the short-term results of our study show that the complete removal of organic matter through scalping supports the establishment and initial growth of conifer seedlings without significant differences from trenching. On the short term, the effects of scalping on seedling nutrition and growth can be however, masked by the residual effect of nutrients exported from the nursery in the peat root plug (Idris et al 2004). The independence between measured soil and needle nutrient concentrations ( Fig.…”

“…Idris et al (2004) and Heiskanen et al (2009) found that nutrient loading stimulates growth, especially in low fertility sites where the relative difference between loaded and unloaded seedlings was greater compared with seedlings grown in richer soil. Our results concerning nutrient loading and soil fertility are in line with their findings.…”

We studied the effects of late season nutrient loading (NLOAD) on the timing of bud burst, growth and changes in nitrogen (N) concentrations in the first growing season after seedlings were outplanted. Two-year-old Norway spruce (Picea abies (L.) Karst.) seedlings with three foliar nitrogen concentration levels (NLOAD levels 11.3, 22.5 and 27.5 g N kg -1 for L, M-and H-seedlings, respectively) were examined in the following three experiments: root growth capacity test (RGC), rooting experiment in the field and soil fertility experiment ('rich' or 'poor' soil) in the field. Bud burst in RGC was monitored daily and foliar N concentration (field experiments), height and root growth (rooting experiment) at monthly intervals. With respect to the RGC test, no differences in root growth were observed among the three NLOAD levels, but buds of H-seedlings burst 2-6 days earlier than others. In the rooting experiment, nutrient loading increased height and root growth but did not affect the timing of height growth. In the soil fertility experiment, foliar N of H-and M-seedlings decreased rapidly, but the decline was slower in rich soil. Current-year needles had more N in seedlings growing in rich soil and the N concentration declined until height growth ceased whereafter it increased until autumn. Improved growth from nutrient loading seems to last only for the first season after planting and the greatest benefits are enjoyed by seedlings planted in poor soils.
