Long term carbon sequestration in soil had been advocated in almost
all the international forum to minimize the global warming. However,
the extent of carbon storage in soil will depend on the type of vegetation it
supports. The study examined different land use potentiality in sequestering
carbon in soil on the basis of extent of tree component. In addition it
was also investigated that how soil carbon is related with other physical
and chemical parameters of the soil in different land uses. Farmers will
adopt a particular land use system only if it fits in his socio-economic
frame work. Hence, bioeconomics of different land uses were also calculated
and compared. Extent of tree in the land use affected the physical
and chemical properties of soil. The pH of the soil decreased from 6.09
to 5.09 and bulk density from 1.55 to 1.21 g/cm3 as the tree component
increased. Available soil nitrogen increased from 97 to 143 kg/ha and organic
carbon from 0.39 to 1.77 per cent. Out of the four soil depths surface
soil had less pH, bulk density and moisture, however soil nitrogen and organic
carbon was higher. Physical characters of the soil were found to be
more related with organic carbon in land uses which are devoid of trees
or when their number was less. However, as the tree component increases
both physical and chemical component needs to be taken simultaneously to
get better estimate of carbon. Agroforestry systems (agrihorticulture) seems
to be better land use practices as they fulfill the needs of the farmers and
can also earn carbon-credits thus increasing their income by 21 per cent.
