19. Agriculture converts inert nitrogen into a range of
reactive compounds damaging to the environment

The greenhouse effect of N2O is approx. 300 x that of
CO2 and has the largest impact on total global
warming after CO2 and methane

20. What is the Eutrophication (EP) and Acidifcation
Potential (AP)?
 Eutrophication Potential (EP) is used to assess the results of the over-supply
of nutrients that reach water systems. The nutrient enrichment of soils through
agriculture can eventually lead to drinking water contamination and soil acidifcation.
 The main sources are nitrate (NO3-) and phosphate (PO43-) leaching into water and
ammonia (NH3) emissions into air. Both NO3- and NH3 emissions are associated with
broiler production.
 Acidifcation Potential (AP) is an indicator of potential reduction of soil pH
caused by ammonia emissions(NH3) and sulphur dioxide (SO2).
 When released into the atmosphere, SOx and NOx can mix with rainwater forming the
acids H2SO4 and HNO3.
 In poultry production, NH3 is released from poultry house litter as well as when it is
spread on felds.

phytase activity infeedstuffs1 (Eeckout and de Pape, 1994)
1 FTU corresponds to the amount of enzyme that liberates 1 mol inorganic orthophosphate
per minit from 0.0051 mol/L sodium phytate at pH 5.5 and 37°C

38. Poultry Operations, saving
energy and GHG

39. Poultry Operations
(Dunkley, 2011)
Propane Use:
• Broiler and pullet farms – 68% of
emissions
• Breeder farms – 3% of emissions
Reduce heat loss in houses
• Insulated curtains (houses without
walls)
• Insulate walls and ceilings

• Improve energy efficiency
• exhaust fans
• lighting
• Generators
• Install circulatory fans to
