| description | Purpose
A study was carried out to understand the carbon sequestration potential of the coastal acid sulfate soils of wetland agroecosystems
Kari
and
Kayal
of
Kuttanad
, Kerala.
Methods
Soil profiles excavated in these lands were studied for their physico-chemical and morphological properties and classified according to USDA based soil taxonomy.
Results
The soils were very deep with moderately deep (97 cm) and moderately shallow (75 cm) solum thickness and both the soils were acidic,sulfuric and/or sulfidic and saline.The BaCl
2
acidity,exchangeable Al,total exchangeable bases and cation exchange capacity were higher in
Kari
soils.Both the soils recorded high sulfate S,which was higher in
Kari
soils.Based on the USDA soil taxonomy,
Kari
soils were classified to
ferrihumic, euic, isohyperthermic, Typic Sulfohemists
and
Kayal
soils to
loamy, mixed, super-active, isohyperthermic, Salidic Sulfaquepts
at the family level.
Conclusion
The organic carbon stock was higher in the sub-surface layer (30-100 cm) which recorded 2769.63 and 645.45 Mgha
− 1
in
Kari
and
Kayal
lands respectively. The soil carbon sequestration potential was higher in
Kari
soils and the highest rate of C sequestration was at the depth 30–60 cm(656.09 kgm
− 3
) and soil layer was proved to have the capacity to hold 20.40 TgC with a total of 58.86 TgC in 11,250 ha of
Kari
lands for a thickness of 150 cm, while
Kayal
soils recorded the maximum at the depth 60-90 cm (163.43 kgm
− 3
) with a capacity to hold 3.29 TgC with a total of 21.02 TgC in 13,000 ha of
Kayal
lands for a thickness of 150 cm in 13,000 ha of
Kayal
lands. |
