- class RUFAS.biophysical.manure.storage.compost_bedded_pack_barn.CompostBeddedPackBarn(name: str, storage_time_period: int | None, surface_area: float = inf, cover: StorageCover = StorageCover.NO_COVER)#
Bases:
Storage- __init__(name: str, storage_time_period: int | None, surface_area: float = inf, cover: StorageCover = StorageCover.NO_COVER)#
Initializes a manure Storage.
- process_manure(current_day_conditions: CurrentDayConditions, time: RufasTime) dict[str, ManureStream]#
Processes manure in compost bedded pack.
Parameters#
- current_day_conditionsCurrentDayConditions
The current day conditions.
- timeRufasTime
The time of the simulation.
Returns#
- dict[str, ManureStream]
_The processed manure stream.
- _apply_dry_matter_loss(methane_emission: float, carbon_decomposition: float) None#
This function calculates and then applies the dry matter loss to the received manure in place.
Parameters#
- methane_emissionfloat
The methane emission on the current day, kg/day.
- carbon_decompositionfloat
The carbon decomposition on the current day, kg/day.
Raises#
- ValueError
If any of the dry matter loss calculations results in negative values for received-manure non-degradable volatile solids, degradable volatile solids, or total solids.
- _apply_nitrogen_losses(storage_nitrous_oxide_N: float, storage_ammonia_N: float, storage_N_loss_from_leaching: float) None#
This function applies the nitrogen losses to the received manure nitrogen and ammoniacal nitrogen in place.
Parameters#
- storage_nitrous_oxide_Nfloat
The nitrogen loss through nitrous oxide emissions on the current day, kg.
- storage_ammonia_Nfloat
The nitrogen loss through ammonia emissions on the current day, kg.
- storage_N_loss_from_leachingfloat
The nitrogen loss through leaching on the current day, kg.
Raises#
- ValueError
If the total nitrogen losses are greater than the total received manure nitrogen.
- static _calculate_cbpb_nitrous_oxide_emission(received_nitrogen: float, is_bedding_tilled: bool) float#
Calculate the nitrogen loss from nitrous oxide emission in a compost bedded pack barn.
Parameters#
- received_nitrogenfloat
The mass of nitrogen present in the manure excreted by animals (kg).
- is_bedding_tilledbool
Indicator for if the bedding is tilled for the current simulation day.
Returns#
- float
The nitrogen lost to nitrous oxide emissions in the compost bedded pack barn (kg).
Raises#
- ValueError
If the daily nitrogen input is negative.
- static _calculate_cbpb_ammonia_emission(received_nitrogen: float, is_bedding_tilled: bool) float#
Calculate the nitrogen loss from ammonia emission in the compost bedded pack barn.
Parameters#
- received_nitrogenfloat
The mass of nitrogen present in the manure excreted by animals (kg).
- is_bedding_tilledbool
Indicator for if the bedding is tilled for the current simulation day.
Returns#
- float
The nitrogen lost to ammonia emission in the compost bedded pack barn (kg).
Raises#
- ValueError
If the daily nitrogen input is negative.
