This document discusses carbon sequestration in soil. It aims to reduce greenhouse gases in the air by capturing carbon in stable forms in soil. This improves soil structure and fertility, leading to increased crop yields. Methods of soil carbon sequestration include ocean storage, geological injection, and terrestrial sequestration. Case studies examine using models to predict global sequestration rates and the impact of tillage practices and cover crops on soil organic carbon levels. Implementing recommended land management practices can help sequester carbon in Indian agricultural and grassland soils.

2. Objectives Of Carbon Sequestration
in soil
 Developing technologies to reduce rate of
concentration of greenhouse gases in air.
 Reducing pollutants in air as well as improving
natural carbon content in soil .
 Improvement of soil structure and restoring
degraded soil leading to increase yield in crops
.

3. What is a greenhouse gas ?
A gas which absorbs and emits radiation is called
greenhouse gas (GHG)
Lists of GHG and their sources
GHG SOURCES
Carbon dioxide Burning fossil fuels
Methane Wetlands , landfills, rice
fields
Nitrous oxide vehicular emission,
industry
CFC’s Refrigerators, aerosol
spray
Ozone Nox , Voc, heat & sunlight

4. One proposed method to reduce this carbon dioxide
in air is by storing/capturing the carbon by
converting the carbon into stable form this process is
called CARBON SEQUESTRATION.
Methods to sequester carbon :
 Oceanic sequestration
 Geological injection
 Mineral carbonation
 Terrestrial sequestration

5. CASE STUDY 1 (Rolf Sommer et al.,2014 international
center for tropical agriculture, kenya)
 It discusses about the sequestration of carbon in soil
at global level according to SRES-A2(special report on
environment scenario).
 This type of dynamics can be used for predicting
sequestration rate for both agricultural crop(arable
land) and grass land areas (meadows).

6. SOC SEQUESTERED OVER THE
YEARS(Rolf Sommer., et al2014)

7. Determination of Soil organic carbon
SOC = SOCo + ( ( a / (1+ e^(t - to/b) )
a & b are empirical constants, SOCo is initial
organic content in soil, t & to are time
expressed in years .

8. CASE STUDY 2 (R lal ,.2007carbon management
& sequestration ,USA)
 It states that carbon sequestration implies to
transfer of CO2 into other long lived carbon
pools.
Some of the carbon pools are:
 scrubbing & mineral carbonation
 Bio fuels(Himmel et al.,2007)
 Biotic sequestration

9. CASE STUDY 3(Kenneth r et al,.2014 Treatment to
determine SOC)
In this paper they discuss about land management
practices need to be done for a better sequestration of
carbon into soil , some of the methods are :
 Conventional tillage
 Crop rotation
 Mulch tillage
 Carbon farming

10. Conventional tillage Mulch tillage

11. Futuristic implications
 As mentioned in SRES-A2 (IPCC,2007)
agricultural and grassland areas can be used
to sequester carbon into soil in INDIA.
 Recommended management practices can
be implemented
 Cover crops help in reducing soil erosion
 Dead sugar plant can be use in generating
bio fuels .
