N Input Root:Shoot Adjustment Factors

Adjustment factors for root-to-shoot ratios based on nitrogen input levels. Higher N availability reduces root allocation (functional equilibrium theory).

Format

A data frame with columns:

N_input_class

N application category name.

N_input_min

Lower bound of N rate (kg N/ha/yr).

N_input_max

Upper bound of N rate (kg N/ha/yr).

RS_adjustment

Multiplicative factor on default RS ratio.
