Survival and growth of Scots pine (<i>Pinus sylvestris)</i> seedlings in north Sweden: effects of planting position and arginine phosphate addition

Forest regeneration by tree planting on harvested sites in the boreal forests of northern Europe is frequently preceded site preparation to increase survival and growth seedlings. We studied whether a small addition arginine phosphate (AP treatment) at time would further enhance seedlings’ early performance. Following two seasons, we investigated Scots pine (Pinus sylvestris) seedlings 11 locations between latitudes 61.1°N 67.1°N forest Sweden. The positions were capped mounds bare mineral soil following mechanical preparation, non-prepared soil. found that seedling increased with AP treatment. On mounds, was more variable appeared dependent precipitation during first month after than positioned positive effect treatment differed pronounced longer growing seasons. had no significant planted soil, while higher fertility using this position.
