Here is the call graph for this function:

update_rooting_depth()

elemental subroutine, public rooting_depth__fao56::update_rooting_depth	(	real (c_float), intent(inout)	zr_i,
		real (c_float), intent(in)	zr_max,
		integer (c_int), intent(in)	landuse_index,
		real (c_float), intent(in)	kcb )

Calculate the effective root zone depth.

Calculate the effective root zone depth given the current stage of plant growth, the soil type, and the crop type.

Parameters

[in,out]	Zr_i	Daily rooting depth estimate.
[in]	Zr_max	The maximum rooting depth for this crop.
[in]	landuse_index	Index corresponding to the line number of the table that holds data for a particular landuse.
[in]	Kcb	current crop coefficient value for a cell.

Note

Implemented as equation 8-1 (Annex 8), FAO-56, Allen and others.
