  1. Managing carbon and nutrients for sustainable agriculture systems in Washington State Climate Friendly FarmingTM Chad Kruger BIOAg Educator Ctr. For Sustaining Ag & Natural Resources WSU Sustainability Week October 23, 2006

  2. The Mission of CSANR is to . . . develop and foster agriculture and natural resource management that is • economically viable • environmentally sound, and • socially acceptable through interdisciplinary relationships between WSU, growers, industry, environmental groups, agencies, and the people of Washington.

  3. Climate Friendly FarmingTM:Moving from Source to Sink Washington State University helping farmers develop and implement agricultural systems and practices that mitigate global climate change.

  5. Global Carbon Pools / Annual Flux Atmosphere, 750 Gt Fossil fuels, 4000 Gt Terrestrial, 2000 Gt Soil 1550 Gt Biota 450 Gt Oceans 38,000 Gt Lal et al. (1995)

  6. Global Environmental Degradation

  7. Agriculture as a source of GHG’s • Ag emits approximately 7% of US greenhouse gas emissions, the third largest source after the energy and transportation sectors (EPA 2004); ~20% of global emissions. • 65% of methane emissions are from agriculture (methane is 21 X’s as potent of GHG as CO2). • 40% of N2O emissions are due to agriculture (nitrous oxide is 310 X’s as potent of GHG as CO2).

  8. Carbon Sequestration: Tillage, Crop Rotation Impact of crop rotation on soil carbon storage

  9. N2O Fluxes – Quincy Sand (Patterson)

  10. Site-Specific N Management Soil Organic Carbon (0-10 cm, g/kg) Nitrogen Use Efficiency: Managing variability in the landscape 10 – 20% reduction in N applied without yield/quality consequence

  11. Rapeseed Crambe Safflower Mustard Soybean Flax Sunflowers Biomass Energy and Products from Agriculture

  12. Home Grown Energy: Biomass Crops Blue-bunch wheat grass switchgrass Reed canary grass Hybrid poplar

  13. Wang, 2005
