Root data										
remarks:	data H. Persson (2000); method: Stober et al (2000)									
 	Spruce stand 100S. In the stand coring was made close to five observation-windows representing 5 different trees.									
	At 4 distances from the tree 2 cores were taken and put together.									
	In the spruce stand LFH-layer was measured and calculated as a mean for 2 core samples.									
	In May96 LFH-layer was 3.81cm with std 2.18. In July LFH -layer was 3.16cm with std 2.35.In September it was not determed.									
	In Oktober  LFH-layer was 4.50cm with std 1.31. In May97 LFH -layer was 4.18cm with std 1.64. 									
	Roots >1mm were too skattered in their distribution to give reliable results.
