Soil characteristics																				
remarks:	Data from T. Persson (2000a); method:  T Persson et al (2000)																			
	Sampling date 14-15 August 1994; number of samplings is 4. CEC and BS are determined from NH4OAc extractions at pH=7																			
	Al is extracted with 1M KCl and assumed to be Al3+

Actual soil moisture content																
remarks:	data from JH Jussy (1998) 	
	To get the data for the whole soil (fine earth + gravel) humidity was related to the mean % of fine earth 	
	(that is 60%); within the soil volume fine; earth density 0.56; gravel density 2.4	
	g/g: water weight/dry fine earth
