\usage{
f_time_norm_focus(object, ...)

\method{f_time_norm_focus}{numeric}(
  object,
  moisture = NA,
  field_moisture = NA,
  temperature = object,
  Q10 = 2.58,
  walker = 0.7,
  f_na = NA,
  ...
)

\method{f_time_norm_focus}{mkindsg}(object, Q10 = 2.58, walker = 0.7, f_na = NA, ...)
}
\arguments{
\item{object}{An object containing information used for the calculations}

\item{\dots}{Currently not used}

\item{moisture}{Numeric vector of moisture contents in \\\% w/w}

\item{field_moisture}{Numeric vector of moisture contents at field capacity
(pF2) in \\\% w/w}

\item{temperature}{Numeric vector of temperatures in °C}

\item{Q10}{The Q10 value used for temperature normalisation}

\item{walker}{The Walker exponent used for moisture normalisation}

\item{f_na}{The factor to use for NA values. If set to NA, only factors
for complete cases will be returned.}

\description{
Time step normalisation factors for aerobic soil degradation as described
in Appendix 8 to the FOCUS kinetics guidance (FOCUS 2014, p. 369).

\examples{
f_time_norm_focus(25, 20, 25) # 1.37, compare p. 184

D24_2014$meta
# No moisture normalisation in the first dataset, so we use f_na = 1 to get
# Temperature only normalisation as in the EU evaluation
f_time_norm_focus(D24_2014, f_na = 1)
# Moisture normalisation for the other four soils is one, as soil moisture
# is higher than the approximate field capacity derived from the USDA soil
# type
