Use fertilizer
A controlled study in temperate montane forest in 1995-1998 in Switzerland (2) found no effect of fertilizing on the growth rate of Norway spruce Picea abies. Annual increase in height (unfertilized: 11-12 mm; nitrogen addition: 15-16 mm) and diameter (unfertilized: 5 mm; nitrogen addition: 3 mm) was similar between treatments. Monitoring was in 1996-1998 on four trees inside a 1,500 m2 plot with nitrogen fertilizer added (30 kg N/ha/year starting in 1995) and on five trees in the unfertilized surroundings.
