Calculates the contribution of an individual feed component to nitrous oxide (N2O) emissions from crop residues decomposition in feed production, using feed-specific emission factors weighted by the component's share in the ration.

Usage

calc_n2o_ration_crop_residues(feed_ration_fraction, n2o_feed_crop_residues)

Arguments

feed_ration_fraction

Numeric. Proportion of a specific feed component in the total ration, expressed as its fraction of diet dry matter intake (fraction). Within each herd_id and cohort, proportions should sum to 1.

n2o_feed_crop_residues

Numeric. Nitrous oxide (N2O) emission factor of a feed component, representing N2O emissions from crop residues decomposition in feed production, expressed per kg of dry matter intake (g N2O/kg DM).

Value

Numeric. Contribution of an individual feed component to the diet-level average nitrous oxide (N2O) emission factor from crop residues decomposition in feed production (g N2O/kg DM).

Details

The contribution is computed as:

$$diet\_n2o\_feed\_crop\_residues = feed\_ration\_fraction \times n2o\_feed\_crop\_residues$$
