  • Animal stocks (Number of animals per category: non-dairy cattle; dairy cattle; pigs; sheep and goats; poultry., type: model (from/to model))
  • Feed crop requirement (Total amount of feed required for the production of animal products. Grass and fodder species are consumed by grazing animals only (dairy and non-dairy cattle, sheep and goats), while pigs and poultry are fed feed crops and other feedstuffs., type: model (from/to model))
  • Grass requirement (Grass requirement; ruminants (nondairy cattle, dairy cattle, sheep and goats) are grazing animals, and part (in mixed systems) or most (pastoral systems) of their feed is grass, hay or other roughage; this grass requirement is calculated as a fraction of the total energy (feed) requirement., type: model (from/to model))
  • N and P discharge to surface water - grid (N and P discharge to surface water., type: model (from/to model))
  • N and P in wastewater discharge - grid (Discharge of N and P to surface water from wastewater., type: model (end-indicator))
  • NH3 emissions - grid (Ammonia emissions from applied nitrogen fertiliser and manure., type: model (end-indicator))
  • Soil N budget - grid (N budget in the soil, used to calculate fate of nitrogen in the soil-hydrology system and for determining emissions to the atmosphere., type: model (end-indicator))
  • Soil P budget - grid (P budget in the soil, used to calculate fate of nitrogen in the soil-hydrology system (residual soil P or surface runoff)., type: model (end-indicator))
