Public Member Functions
virtual void	reset (MoBiLE_Plant *)=0
	Resets rooting depth, fine root mass and fine root distribution of a plant.
virtual void	set_rooting_depth (unsigned int &, MoBiLE_Plant *, double, double _max_rooting_depth=invalid_dbl)=0
	Sets the rooting depth (bounded by a maximum or ZRTMC) and the number of rooted layers.
virtual void	update_root_fraction_sigmoid (double, unsigned int, double, double, double, double, MoBiLE_Plant *)=0
	Updates the fine root distribution with the sigmoid shape (Sigmoid root distribution).
virtual void	update_root_fraction_exponential (double, unsigned int, double, MoBiLE_Plant *)=0
	Updates the fine root distribution with the exponential shape (Exponential root distribution).
virtual void	update_roots_static (const double, unsigned int &, MoBiLE_Plant *, ldndc::growable_array< BaseRootSystemDNDC *, 1000, 1 > &, double)=0
	Root growth of one time step, static approach (Static root growth model).

Detailed Description

Interface of the fine root system of a plant: rooting depth, distribution of fine root mass and length across soil layers, root growth restrictions and nitrogen uptake (see Root system).

Throughout, the "number of rooted soil layers" is the index of the first soil layer without roots; the layer containing the root tip counts as rooted.
