  1. ETS and the Arable industry Stuart Wright

  2. New Zealand’s Greenhouse Gas Inventory 1990–2010 • Agriculture (chapter 6) • 2010 • The agriculture sector was the largest source of emissions in 2010, contributing 33,748.4 Gg CO2-e (47.1 per cent) of total emissions. New Zealand has a unique emissions profile amongst developed countries. In most other developed countries, agricultural emissions are typically less than 10 per cent of total emissions. • The largest sources of emissions from the agriculture sector in 2010 were enteric fermentation from dairy cattle and sheep, and nitrous oxide emissions from agricultural soils.

  3. Yield trends in wheat UK and New Zealand

  4. Cultivation practice following grass Can we lower our crop establishment emissions without reducing our crop yields and margins?

  5. Spring barley yields Year 1 - 3 (t/ha) Wanganui 2009 - 2011 Yields based on plots receiving same of nitrogen as paddock approx 90 kg N/ha for the spring barley

  6. The Sirius Wheat Calculator software 2012 Wheat Calculator will be available from Rob Craigie at FAR from late July. Email: craigier@far.org.nz

  7. maximum 2000 seed yield 1500 Seed yield (kg/ha) 1000 Luxury uptake minimum plant N 500 for max yield 0 0 50 100 150 200 250 300 350 400 Total plant N [straw+seed+roots] (kg N/ha) Optimising ryegrass seed yields with less N input
