...	Currently not used
moisture	Numeric vector of moisture contents in \% w/w
field_moisture	Numeric vector of moisture contents at field capacity -(pF2) in \% w/w
temperature	Numeric vector of temperatures in °C
Q10	The Q10 value used for temperature normalisation
walker	The Walker exponent used for moisture normalisation
