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 Jussy (1998)															
 	To get the data for the whole soil (fine earth + gravel) humidity was related to the mean % of fine earth 															
	(that is 55%); within the soil volume fine earth density =0.7 gravel density 2.4
