2. INTRODUCTION
 In pre-industrial times, every million molecules of air
contained about 280 molecules of carbon dioxide.
Today that proportion exceeds 380 molecules per
million.
 If carbon dioxide levels continue upward, further
warming could have dire consequences, resulting
from rising sea levels, agriculture disruptions, and
stronger storms (e.g. hurricanes) striking more often.
 Fossil fuels, which provide about 85 percent of the
world’s energy, are made of hydrocarbons, and
burning them releases huge quantities of carbon
dioxide.

4. WHAT IS CARBON
SEQUESTRATION ?
 Carbon sequestration is capturing the carbon dioxide
produced by burning fossil fuels and storing it safely
away from the atmosphere.

5. HOW DO WE CAPTURE CO2 ?
 There are several processes that captures CO2 some of
them are:
 Commercial Carbonization in beverage industries , dry
ice manufacturing.
Crystal structure of dry iceCarbonated water

TECHNIQUES TO ENHANCE CARBON SEQUESTRATION IN
SOILS
Crop rotation

7. Why Tillage
 Eliminate soil compaction
 Control weeds
 Eliminate residue
 Harbor insects and diseases
 Tie up fertilizer N
 Barrier for herbicide
 What hard working
people do
 Sense of accomplishment
 Cleansing operation
 Why not?
Because it causes soil erosion and reduces soil organic matter

9. Potential cost of soil
sequestration of soil
 Nitrogen fertilizer
Nitrogen fertilizer can increase soil
organic matter because nitrogen is
often limited in agro ecosystems.
 Growing plants on semi-arid
lands
Growing plants on semiarid lands
has been suggested as a way to
increase carbon storage in soils.

10.  Burning coal with pure
oxygen rather than
atmospheric air.
 Replacing smoke stacks with absorption tower

11. CONCLUSION
 Carbon sequestration can be done to
reduce the carbon content in
atmosphere but not totally.
 Apart from reducing the global CO2
levels, soils carbon sequestration is a
strategy to achieve food security
through improvement in soil quality.
 Carbon sequestration will enable us
increase and maintain retention time
of CO2 in soils, water bodies etc.
