Miscalculated Kc on cycle ovelapping 2 civil years
On the following example:
crop_params <- CropWat::get_crop_params("FAO-GRAPES-W")
crop_params$sowing_date <- "10-01"
meteo <- ZH_3_clim[ZH_3_clim$Date >= as.Date("2010-01-01") &
ZH_3_clim$Date <= as.Date("2014-12-31"), ]
cw_input <- CropWat::CW_create_input(cp = crop_params,
DatesR = meteo$Date,
ETo = meteo$ETP,
P = meteo$Ptot,
soil_depth = 1,
AWC = 100)
plot(cw_input)
We obtainsomething like this:
The value of Kc is invariant at 0.3 whereas it should vary between 0.3 and 0.7 depending on the crop period.
