Title of the paper: Basal Area Increment in Different Stem-Heights of Norway-Spruce Stands Following Fertilization. 30 stem-analyses of variously fertilized sample plots show the reaction in basal area increment in supper stem-heights for periods of 3,6 and 12 years. Fig. 1 to 4 show single trees (fertilized and unfertilized) , Fig. 5 to 8 means of 2 quickly growing and 2 slowly growing groups of trees. Fig. 9 to 12 indicate the difference of periodical increment (means of 5 trees per plot) as compared to the untreated plot, gif. 13 to 22 the differences between the period before and after the treatment (periods of 3 and 12 years).
