farmingpy.apsim.SoilOptimizer

class SoilOptimizer(model, params, obs_yield, obs_lai, harvest_date, zone_names=None, multithread=True)

Optimize soil paramters.

__init__(model, params, obs_yield, obs_lai, harvest_date, zone_names=None, multithread=True)

Optimize model parameters

Parameters:

• model – APSIMX object

• params – Dictionary of soil parameters to optimize with allowed ranges. The range indicates difference to original values. e.g. {"ll15" : (-0.01, 0.05), "dul" : (0.0, -0.05)}. Supported parameters are: ll15, dul, no3, nh4, urea. The same change is applied to all soil layers.

• obs_yield – Dataframe with observed yield for each zone.

• obs_lai – Dataframe with observed LAI for each zone.

• harvest_date – Harvest date as datetime

• zone_names – Name of zones to optimize.

• optional – Name of zones to optimize.

• multithread – Allow APSIM to use multiple threads, by default True

• optional – Allow APSIM to use multiple threads, by default True
