FIGURE 22. NUTRIENT APPLICATION PER USABLE HECTARE – GREENHOUSE GAS EMISSIONS - Participant farms in the North emitted an average of 15.4 t CO2-e/t MS in 2016-17 which was higher than 13.3 t CO2-e/t MS in 2015-16. Methane was the main greenhouse gas emitted from fertiliser, effluent management systems and animal wastes participant farms in the North accounting for 10.4 t CO2-e/t accounted for 0.9 t CO2-e/t MS. The balance of 0.7 t CO2-e/t MS, 68% of the average total greenhouse emissions. MS came from ammonia and nitrate loss in soils as indirect Methane produced from ruminant digestion contributed 9.1 t sources.

When seasonal conditions improved, good soil moisture levels allowed large amounts of pasture to be grown and increase stored fodder reserves on farm.
