Arguments

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
object

An object containing information used for the calculations

...

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

f_na

The factor to use for NA values. If set to NA, only factors +for complete cases will be returned.

study_moisture_ref_source

Source for the reference value +used to calculate the study moisture. If 'auto', preference is given +to a reference moisture given in the meta information, otherwise +the focus soil moisture for the soil class is used
