RUFAS.biophysical.manure.storage.open_lot module#

class RUFAS.biophysical.manure.storage.open_lot.OpenLot(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 open lot.

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_open_lot_ammonia_emissions(received_nitrogen: float) → float#

Parameters#

received_nitrogenfloat: The amount of nitrogen present in the manure excreted by animals (kg).

Returns#

float: The amount of nitrogen lost to ammonia emission (kg).

Raises#

ValueError: If the daily nitrogen input is negative.
