Nick Ritar from Milkwood Permaculture explained the opportunity presented by this Australian land managment technique, at the Carbon Farming Conference & Expo at Orange NSW Australia November 2009
20. 1. Plow to 2” below new root depth 2. Remove stock for 4-6 weeks 3. Just at onset of flowering: Planned graze to 3 leaf stage Existing Condition: Shallow, Compacted, Drought-Prone Topsoil 1. Soil Test – Mineral/Soil Food Web 2. Plow to 2” below hard pan 3. Remove stock for 4-6 weeks 4. Just at onset of flowering: Planned graze to 3 leaf stage 1. Plow to 2” below new root depth: Max out at 12-15” 2. Remove stock for 4-6 weeks 3. Just at onset of flowering: Planned graze to 3 leaf stage Yeomans Keyline Plow – Plowing for Rapid & Cheap Soil Development (Pasture) And Another Thing: 1% increase in Organic Matter = 57 tonne/ha capture in Atmospheric CO2 ! (That’s twice your total annual emissions)
34. CO 2 Sequestration - Trees or Soil or Both? Zone 4 TREES CONS: Expensive & Slow ($2000/ha & 15+ years to sequester 200 tonnes/ha CO 2 ) Locks up land from production PROS: Climate/Landscape stabiliser/modifier High values where harvested More Effective SeqC in Tropics SOILS CONS: Measuring? Maybe PROS: Cheap & Fast ($20/ha & 1 year to sequester 57 tonnes/ha CO 2 ) Requires production to develop Organic by default More Effective in Temperates/Drylands TREES & SOILS Stable & productive integrated system!

Editor's Notes
“ Wetlands can capture carbon at a tremendous rate,” says UC Davis soil biogeochemist William Horwath. An acre can grow about 15 tons of plant material per year, which contains about 8 tons of carbon. Of that, 90% is lost to bacterial decomposition and the rest is captured in soil. The Delta is particularly well suited to carbon-capture farming. “It's one of the most productive ecosystems on the planet,” says Horwath, who is also the UC Sustainable Agriculture Farming Systems (SAFS) project leader. “There are lots of nutrients and the climate is ideal.”
