Spruce site Sko: Soil organic matter data														

Carbon and nutrient pools - organically bound														
remarks:	data from Bergholm (2000)													
 	Sampled in Oct 1993; data Johann Bergholm. Dept of Ecology and Environmental Research. Swedish University of Agricultural Sciences. Box 7072. S-750 07 Uppsala													
	C and N are analysed by Carlo Erba element analyser. The other elements are first extracted with a mixture of HNO3 													
	and HClO4 at about 120 degrees. The  results from the mineral soil contain both organic bound elements and what 													
	could be desolved from mineral soil (indicated with d).
