  • 1. Forests Can They Save Us from Ourselves?

2. Carbon Sequestration in Radish PlantsPlants use CO2 from the atmosphere for twoprimary purposes:1. To make sugar to burn for energy (respiration)2. To use in creating other carbon compounds (i.e. proteins, carbohydrates, fats etc.) for building their structures. These carbon compounds stored in these structures are sequestered. 3. Misconception! Many people think that trees will soak-up all the extra carbon being put into the atmosphere Plants especially forests- are able tosequester large amounts of carbon.But. Soil fertility (micro-organisms and nutrients)limit carbon sequestration rates as does age oftrees. 4. Put seeds in container on wet towels.Cover with more wet towels. 5. Cut below the curve of bottle top 6. Insert upper section into lower + secure with a tabof duct tape. Can use coffee filters or handiwipes 7. Fill reservoirs Use filtered H20 8. Label bottles and fill with vermiculite perlite mixture1:1 You now have a hydroponic set-up ---no soil! 9. Growth of a Radish Plant http://www.youtube.com/watch?v=d26AhcKeEbE 10. Cotyledons provide both nutrients and photosynthesize.When true leaves develop, they take over photosynthesizing =feeding the plants. Cotyledons drop off 11. CalCarb A Foliar Spray designed to deliver moreCO2 to stomata. Spray on underside of leaves 12. Start spraying CalCarb solution 2x/week under the cotyledonsand then under true leaves. Make sure CalCarb solution iswell mixed before spraying. 13. Will not see important differences between control and no fertilize plants until true leaves have taken over.True leaves may not form. Yellowing will occur. 14. CO2 Enhanced vs ControlCut off radishes at node between stem and root. Mass out 1-3 of the most robust plants. 15. Control vs No fertilizer 16. Alternatives- Grow in Trays. Kids can then snip off plants fromthe trays and measure. Can use corn but may have toeliminate Calcarb. 17. SOIL, MICROBES and ROT! 18. Soil Respiration Test Using Limewater CO2 + Ca(OH)2 ---> CaCO3 + H2O
